Does Hong Kong recommend scaling every six months? Quadrant-based fees, eight subsidy schemes and a rule that never existed, 2026

TL;DR There is no such rule. What the Department of Health publishes is not a scaling interval but an oral check-up interval, and for most people it is once a year; every 6 months or more often is written only for 5 categories of people at high risk or with special needs. Nor can the fees be compared directly: on one and the same price list, scaling at $980 is charged per visit while deep scaling at $4,250 is charged per quadrant of the mouth, and the mouth has four quadrants.

#"Scaling every six months" — Hong Kong has no such rule

The biggest misconception: no Hong Kong authority has ever published a "scaling interval". What it publishes is an oral check-up interval, and for most people that is once a year.

The Chinese version of the Oral Health Education Division's "frequency of oral check-up" page states that a dentist will advise on how often to have an oral check-up according to the individual's oral condition; for most people, an oral check-up once a year will do; every 6 months or more often is written for those at high risk or with special needs [Note 1].

⚠️ The Chinese and English versions are not identical, and the difference is itself useful. The opening sentence of the Chinese version — that a dentist will advise on the frequency according to the individual's oral condition — has no counterpart in the English. In other words, the principle that the interval varies from person to person and is settled by a dentist is written out, in Hong Kong's official texts, only in the Chinese.

The page's list of people at high risk or with special needs, complete, runs to five categories: people with disabilities; people who have had radiotherapy to the head and neck; smokers; people with severe oral disease; and people with systemic disease.

The same body repeats the same interval on its gum disease prevention page: an oral check-up at least once a year, with scaling done at that same visit.

So the accurate statement is: the official recommendation is at least one oral check-up a year, with scaling at that visit if there is calculus; every 6 months or more often is written only for the five categories above. No Hong Kong official document says "scaling every six months".

#A subsidy cycle is not a clinical recommendation

Several numbers in Hong Kong look like an "official scaling interval" and are not:

⚠️ All three are funding cycles or quota cycles, not clinical recommendations. The question they answer is how often the government will subsidise you, not how often you should have your teeth scaled.

Reading a funding cycle as a clinical recommendation is a serious misreading — and most of all in the other direction: if you are in a high-risk group, a subsidy once every 365 days does not mean your clinical need is once every 365 days.

#What is done internationally? NICE says in terms that it exists to abolish the six-month regimen

Paragraph 1.1.1 of the United Kingdom's NICE clinical guideline CG19 (published 27 October 2004) states that the recommended interval between oral health reviews should be determined specifically for each patient on the basis of an assessment of disease levels and risk [Note 2].

The boundaries given at paragraph 1.1.5 are: a shortest interval of 3 months; a longest of 12 months for patients under 18; and a longest of 24 months for patients aged 18 and over.

⚠️ And paragraph 1.1.8 of CG19 refers to "as is the case with the current 6-month recall regimen" — that is, NICE calls the six-month regimen the current practice, and it exists precisely to replace it. Six months is not a clinical finding; it is a convention.

The National Health Service's patient page puts it more plainly still: you may assume you should have a check-up every 6 months, but some people may not need to go so often and others may need more frequent checks; the interval can vary from 3 months to 2 years [Note 3].

⚠️ Two statements at different levels must not be run together. What the Department of Health, NICE and the NHS say above is all about the oral check-up interval. There is a separate statement about how often to have teeth scaled, from a statement of the American Dental Association dated 10 June 2013 — a professional association, not a national body — which cites research indicating that high-risk patients would likely benefit from more frequent visits while low-risk patients may see the same benefits from one cleaning a year, and whose position sentence is that regular dental visits are recommended at intervals determined by a dentist [Note 4].

The three accounts have exactly one thing in common: the interval is set by a dentist for the individual. None of them supports "every six months for everyone".

#Why do quotes differ so much? "One price" is not a comparable number at all

The same word, scaling, is charged in at least four different ways across Hong Kong's published first-hand price lists: per course of treatment, per visit, per quadrant of the mouth, and by who performs it. Compare without first fixing the unit and you will compare wrongly.

St Paul's Hospital Dental Centre's adult price list (printed on the page: Effective on 1/4/2026) states its own basis of charge [Note 5]: consultation fee (general practitioner) $550; scaling $980; deep scaling (per quadrant) (the mouth is divided into four quadrants) $4,250; periodontal examination $750; oral X-ray $300.

⚠️ "Per quadrant" and "the mouth is divided into four quadrants" are the basis of charge printed on the price list itself, not this article's inference.

Do the arithmetic once (using that centre's own published prices):

• One ordinary scaling visit: scaling $980 plus the consultation fee $550 equals $1,530. The consultation fee is a separate line, so "$980 for scaling" is not "$980 a visit".
• Full-mouth deep scaling: $4,250 × 4 equals $17,000. Add the periodontal examination that decides whether you need it at $750 and the consultation fee $550 and you reach $18,300, before the X-ray at $300.
• A check on consistency of units: $980 is "per visit" and $4,250 is "per quadrant". Set $980 against $4,250 and the gap looks like a factor of 4.3; set $1,530 against $18,300 and it is about a factor of 12. The difference comes not from one being dearer than the other but from the unit.

That centre's children's price list has no deep scaling line at all. The note the price list itself prints is that patients are welcome to ask the dentist about treatment costs and related details before examination or treatment.

Prince Philip Dental Hospital's teaching patient fee schedule (self-dated "fees effective from 1 March 2026"): consultation fee (per day of attendance) $50, but expressly excluding dental hygiene care and orthodontic treatment; dental hygiene care treatment (all diagnosis and treatment within the same course) $100 [Note 6].

Read two things carefully: $100 is for "all diagnosis and treatment within the same course", that is, the whole course — not per visit and not per quadrant; and the consultation fee is expressly not added. So a course of dental hygiene care as a teaching patient has a published fee of $100.

⚠️ But read it together with the hospital's own threshold: the hospital does not provide public dental services; you must go through a screening process assessing your suitability for the designated teaching purposes; waiting times vary from several weeks to several years, and a full course of treatment usually requires more visits than treatment from a private dental practitioner [Note 7]. The Department of Health's own FAQ page says the same thing: the hospital does accept a small number of patients, but their oral condition must suit teaching needs.

In one sentence: the cheapest route is not the fastest, and whether you get in is not up to you — it is up to whether your oral condition suits teaching needs.

The same hospital's private patient fee schedule (self-dated "Price Range w.e.f. 1 August 2016", so the version still online is ten years old) has no line for scaling at all; the closest periodontics line is Non-surgical Periodontal Therapy (per quadrant) $3,000–$8,000 — per quadrant again.

The Chinese University of Hong Kong's University Medical Service is the only published price list that charges by who performs the work (eligibility limit: it applies only to CUHK staff, their families and students, and is not a public price list; it is used here only to show the charging structure). The price list (self-dated "Effective from 1 September 2021"): scaling by a dental hygienist, Terms A 144; scaling or root planing by a dental surgeon, Terms A 288 [Note 8].

The same item, done by a dental hygienist, is half the price of the same item done by a dental surgeon.

The government has itself said that prices vary: the charges of private dentists are not standardised. The same page carries the government's own advice on asking about price: you may first compare prices before deciding whether to accept treatment, and in weighing the charge you should also consider other factors such as the treatment method and the quality of service.

⚠️ And one more thing is itself the answer: most NGO dental clinics do not publish their fees. A number of NGO and charitable dental services in Hong Kong list scaling on their own websites without publishing a fee schedule; the page for Pok Oi Hospital's Kwai Shing Dental Clinic simply says "Fees & Charges: For enquiries, please call us at 3619 0042." This article therefore lists no NGO clinic prices.

#Scaling, deep scaling, oral check-up: which is which

Of these three pairs, it is the third — an oral check-up is not scaling treatment — that most affects how you read the official recommendation.

Plaque is not calculus. Plaque is soft and can be dealt with by brushing and flossing. The Department of Health sets out the relation between the two: plaque is also calcified by saliva to form calculus, and because the surface of calculus is very rough it leads to more plaque accumulating, keeping the gums inflamed and possibly worsening into severe gum disease. The same body's gum disease prevention page says why brushing is not enough: because brushing cannot remove calculus, you have to see a dentist regularly for check-ups and scaling to remove it [Note 9].

Scaling is not deep scaling. Scaling deals with the tooth surface; deep scaling deals with the root surface inside the periodontal pocket, below the gum line.

Gingivitis is not periodontal disease (periodontitis) — but the two are not unrelated diseases either. Both the Chinese and English pages of the Department of Health treat "gum disease" as the umbrella term, with gingivitis as mild gum disease and periodontitis as severe gum disease. The American Academy of Periodontology says the same: gingivitis is the mildest form of periodontal disease.

An oral check-up is not scaling treatment. The annual recommendation the Department of Health publishes is a frequency for the check-up, not for scaling; scaling is listed as one of the "preventive treatments" and is carried out as needed at the same visit as the check-up.

⚠️ If you think "I brush very well, do I really need scaling": brushing and scaling deal with two different things, one with soft plaque and one with calculus that has already hardened.

---

#The difference between the two, and why severe cases need both

The official position is not that deep scaling replaces scaling, but that a severe case "needs to receive scaling and root planing" [Note 10].

⚠️ So putting "scaling $980" and "deep scaling $4,250" side by side as two options is already comparing the wrong things — one is the premise of the other, not a substitute for it.

When is scaling alone enough, and when is deep scaling added? The Department of Health sets out how each of the three grades — mild, moderate and severe — is handled [Note 11]. Mild: daily brushing and flossing to remove plaque, with a dentist scaling away any calculus. Moderate: seek treatment promptly for scaling, removing calculus and the plaque inside the periodontal pocket. Severe: scaling to remove calculus, root planing or periodontal surgery, and antibiotics prescribed as the case requires.

The American Dental Association states the criterion behind the judgement: if gum disease is caught early and has not damaged the structures below the gum line, a professional cleaning should do; but if the pockets between gums and teeth are too deep, deep scaling may be needed [Note 12].

So the criterion is pocket depth, not what you would prefer or which quote is cheaper. And measuring pocket depth is itself an examination that has to be done (the Department of Health specifies a periodontal probe and X-ray), which on St Paul's Hospital Dental Centre's published price list is a separate line.

This is how the disease progresses: untreated gingivitis can advance to periodontitis — plaque spreads below the gum line, toxins from the bacteria trigger a chronic inflammatory response, and the tissues and bone supporting the teeth are broken down and destroyed; the gums separate from the teeth, forming pockets that can become infected, the pockets deepen, more tissue and bone are destroyed, and eventually teeth can loosen and may fall out or need to be removed [Note 13].

Who is especially at risk? The Department of Health's list of risk factors, complete: plaque accumulation, inadequate cleaning of dentures, calculus accumulation, crooked teeth, smoking, stress, hormonal changes in pregnancy, systemic disease (diabetes, leukaemia, AIDS), and medication (antihypertensives and anti-epileptics). The same body also gives the multiple for smoking: smokers can be five times or more as likely to suffer from gum disease as non-smokers.

And one professional body says the consumer term "scale and polish" is itself wrong. The British Society of Periodontology writes on its clinical guideline explanatory page that this does not mean what was done before was wrong or unreasonable, and does not change what is used in practice; but it does mean the death of the term "scale and polish", which can be misleading to a patient with periodontitis — much more than that is being done [Note 14].

The same page carries another sentence very useful to consumers: a non-engaging patient could be held at step one and not move to step two until they are demonstrating that they can improve their plaque control — but that is only true if the patient has been educated on the importance of oral hygiene and shown how to do it.

⚠️ Deep scaling is not a service you can simply buy by paying for it — clinically a dentist may decline to escalate, but that is not an unconditional professional discretion either.

Incidentally, in the official definition polishing is the second step of scaling, not an extra service. The Department of Health's scaling procedure has two steps: first removing firmly attached calculus with dental instruments or an ultrasonic scaler, then polishing or air-abrasion to remove stains and keep the tooth surface smooth. The Department's own Chinese and English pages are inconsistent on this point: in the list of services excluded from the general public dental sessions, the English writes "dental scaling and polishing" while the Chinese writes only 「洗牙」 — the Chinese version treats polishing as part of scaling, consistent with the procedure description.

#What it can do, and what it cannot

What the guidelines can support is that deep scaling has a moderate benefit for chronic periodontitis and is the initial treatment — none of the sources cited here provides an effect figure with a denominator and a control group for either scaling or deep scaling. That gap is itself worth knowing.

What it can do:

• The benefit rating for deep scaling is "moderate". The American Dental Association's 2015 guideline: for patients with chronic periodontitis, scaling and root planing showed a moderate benefit, and the benefits were judged to outweigh potential adverse effects; the panel voted in favour of it as the initial non-surgical treatment for chronic periodontitis [Note 15]. Note the words "initial treatment" — it is the first step of a course, not the end of one.
• The gingivitis stage can be reversed. With professional treatment and good home care, gingivitis is reversible; the Department of Health says the same of mild gum disease.
• Short-term reactions after scaling. The Department of Health: a gum disease patient may feel mild oral discomfort and have bleeding gums for a few days after scaling, which will gradually disappear if oral hygiene is maintained.

What it cannot do:

• It cannot replace daily cleaning. The Department of Health states that root planing must be accompanied by good oral hygiene care, and that a smoker must give up smoking, because smoking makes gum disease hard to heal.
• It is not a one-off. Many patients do not require additional treatment after deep scaling, but the majority of patients will require ongoing maintenance therapy to sustain periodontal health. On Prince Philip Dental Hospital's private patient fee schedule, supportive periodontal care is its own line at $500–$1,500.
• No source says the bone loss of periodontitis is reversible. The American Academy of Periodontology uses "reversible" expressly of gingivitis, but neither it nor the Department of Health says the same of periodontitis.
• It does not guarantee you will have no further problems. Paragraph 1.1.8 of NICE CG19 says so itself: there is no guarantee that new disease will not develop between recall visits.

⚠️ One epidemiological figure to read carefully. The American Dental Association's page cites research from July 2015 in writing that chronic periodontitis affects 47.2% of adults over 30 in the United States. That is a United States figure, and its denominator is the United States adult population over 30. None of the Hong Kong official or academic sources cited here gives a prevalence of gum disease for Hong Kong, so this figure cannot be carried across and applied to Hong Kong.

#How much does government dentistry help? First, a premise most people get wrong

Hong Kong has no public dental service for the ordinary adult member of the public — government dental clinics are mainly for civil servants and their eligible persons, with only about 2% of capacity set aside for general public sessions, and those sessions offer only pain relief and extraction.

Chapter 2 of the Director of Audit's Report No. 82 (published 24 April 2024) puts it most plainly: as of February 2024 the Department of Health operated 43 government dental clinics; those 43 clinics are not for the provision of comprehensive dental services for the general public; and since 1947 the government has used a small fraction, around 2%, of the clinics' service capacity to provide a limited scope of supplementary emergency dental services to the public [Note 16].

What the general public sessions do and do not provide. The Department of Health's general public dental session page (page self-dated 30 July 2026): the emergency services provided include relief of pain or tooth extraction, but not fillings, scaling, dentures, removal of bridges and the like, and extraction before orthodontic treatment is also outside the scope [Note 17].

⚠️ The English version of the same passage carries a restriction the Chinese does not: one tooth per visit. That restriction is independently corroborated by the press release launching the CDSP.

How large is it? The clinic list page names 11 clinics with general public sessions, all of them in the morning, of which the two at Tai O and Cheung Chau run once a month.

But turning up is no longer how you get a place — the way of obtaining a disc has changed. The online registration system for general public dental sessions came into service on 30 December 2024, and the "preliminary registration" arrangement stopped the same day, so the public no longer have to queue at a clinic for a disc; online registration for the ballot runs from 6 o'clock to half past 11 in the morning [Note 18].

The same page sets out two allocation rules: half the quota is reserved for a priority ballot for people aged 65 and over; and a compassionate mechanism — 5 per cent of the first-round ballot quota goes to people who have registered repeatedly within the past 30 days without being allocated a place.

The charges changed on 1 January 2026, and another government page still says "free". The Department of Health's page: from 1 January 2026 the general public dental session service is free for eligible persons; the consultation fee for a person who is not eligible is HK$850, with prescribed medication at $90 an item for up to four weeks.

⚠️ Two government pages contradict each other, and this article follows the newer. The Oral Health Education Division's FAQ page (no date shown on the page) still says the service is free. The Department of Health's dental services page of 30 July 2026 governs.

How tight is supply? The Audit Commission's quota series: from 2014-15 to 2018-19 the number of discs for allocation at the 11 government dental clinics was about 40,000 a year; from 2018-19 to 2022-23 the disc quotas fell from 40,322 to 20,337 while the disc allocation rate rose from 92.3% to 99.2% [Note 19].

The two figures have to be read together: the quota halved, but competition for it intensified. Attendances fell over the same period too: 37,027 in 2018-19, 34,313 in 2019-20, 23,317 in 2020-21, 27,067 in 2021-22 and 20,035 in 2022-23 (11,229 in 2023-24 up to October 2023).

Government press release of 26 June 2025: since the online registration system was introduced, the average utilisation rate of the general public sessions has been as high as 99%, and the quota was increased by close to 30 per cent from June of that year.

⚠️ If you assume that "if I don't want to pay I'll get my teeth scaled at a government dental clinic": the general public sessions expressly do not provide scaling.

#Eight schemes — which ones really subsidise scaling?

Of the eight schemes, six say expressly that they subsidise scaling, and every one of them has an eligibility gate based on who you are.

As for the dentist's assessment, not every scheme states one: the scheme pages for the CDSP, the Outreach Dental Care Programme for the Elderly (ODCP) and PDS2 each state an assessment expressly; the pages for the Primary Dental Co-care Pilot Scheme for Adolescents (PDCC) and Handy Tooth Care (HTC) do not write an assessment as a gate before service [Note 20].

⚠️ The "oral health risk assessment" that appears on the PDCC page is a service item listed within the subsidised scope, not a gate deciding whether you are eligible to receive service — the two must be kept apart. So "every scheme requires a dentist's assessment" does not hold; what holds is that of the five therapeutic subsidy schemes, three state that assessment on their pages.

Two further points must be made clear.

The ODCP and HTC are the only schemes examined here that list "gum disease treatment" as a separate item. The CDSP does not, the PDCC does not, and the general public dental sessions do not. That is, for the overwhelming majority of people, deep scaling falls within no government subsidy at all.

The PDCC's $200 is a "recommended" co-payment, not a fixed price, actually settled by the dentist on joining the scheme.

⚠️ There are two versions of the School Dental Care Service's scope. The Department of Health's FAQ page says the scope includes scaling, filling and extraction, but the five items the service's own website lists contain none of those words. This article records both, and takes the service's own website as the source for its scope.

---

#The Community Dental Support Programme: scaling was only added on 1 January 2026

First a chronology, because it explains why older information does not apply.

The CDSP launched on 26 May 2025, and its subsidised scope at launch covered only oral examination, medication to relieve toothache, X-ray examination, and filling or extraction — no scaling. The press release of 17 December 2025: from the first of January the following year the scope would be expanded to add scaling, root canal treatment, removal of bridges and crowns, and the fitting of removable dentures, and it stated that each participant may receive one scaling service every 365 days [Note 21].

So the effective date of the CDSP's scaling subsidy, as stated by the issuing body, is 1 January 2026.

Three things are easily misread.

First, Category A is not "everything free" — dentures cost $500 a set, and for everything else the government fully subsidises the administrative fee.

Second, Category B is not "$50 to $1,000 across the board" — oral examination, X-ray examination and medication for pain are free for Category B too. What has to be paid for is filling or extraction at $50, removal of a bridge at $100, removal of a crown at $50, scaling at $50, root canal treatment at $50, and dentures at $1,000.

Third, behind every price is a quantity cap that the scheme page prints itself — a unit price does not mean "as many as you like". Every 180 days, at most three "filling or extraction quotas", and one bridge or two crowns; every 365 days, scaling or root canal treatment on one tooth; every 5 years or more, removable dentures at most twice [Note 22].

⚠️ So within one cycle at most three teeth are subsidised for filling or extraction, and from the fourth tooth on you fall outside the subsidy, into what becomes "a private arrangement between the participant and the NGO dental clinic", to be paid for in full. The FAQ adds a time limit: all treatment must be completed within 180 days.

How is a "set" of dentures counted? On the footnote to the Chinese page: the co-payment is counted per set of dentures, meaning the upper or the lower jaw, and fitting removable dentures for both upper and lower jaws counts as two sets. There is a further condition: a participant is provided with the subsidy only if fewer than twenty teeth remain and a dentist assesses that they have difficulty eating or chewing which fitting removable dentures would effectively restore.

⚠️ The FAQ page words the same rule slightly differently: "if a participant has fewer than twenty natural teeth remaining" — with the word "natural" added, so the two pages differ on whether the threshold counts natural teeth or counts dentures as well. This article has no information with which to judge which is right; before counting how many teeth you have left, read both pages.

Do you qualify for the CDSP? Three conditions must hold together: holding a valid Hong Kong identity card or Certificate of Exemption; being a current beneficiary or recipient of one of the Old Age Living Allowance, the Community Care Service Voucher for the Elderly (co-payment level two), the Integrated Home Care Services for frail elderly persons or Home Support Services (level one or level two), medical fee waivers from the Hospital Authority (full or partial), or being a homeless person applying with the help of a social worker at a designated NGO; and being registered with eHealth [Note 23].

There is no age limit. The other rules: unused quota cannot be carried over to the next cycle; quota cannot be shared with anyone else; within one cycle service may be received at only one chosen NGO dental clinic; and Health Care Vouchers may be used to pay the administrative fee or the co-payment.

Scale: the Legislative Council written reply of 21 January 2026 — 32 NGOs are currently participating, providing over 80 service points; and as at 31 December last year, over 5 700 participants had used the service.

#Pilot Dental Scheme Phase Two for civil servants: the government pays for that one time only

The Department of Health's Chinese page (page self-dated 28 July 2026): the service period of Phase Two of the pilot scheme will be extended to 28 February 2027; with the extension, it is expected that a total of about 200 000 civil servants and eligible persons can be arranged to receive one scaling service at a private dental clinic; and the government will subsidise one scaling service only, and will not bear the cost of any other treatment agreed between a participant and a dental organisation [Note 24].

Invitations are issued by the Department of Health in batches by SMS (#DH-CLINICS).

Two sentences are worth noting. First, even once invited, scaling is not automatic: the dentist at the private dental organisation will also make an assessment on the day of scaling to decide whether the invited person is suitable to receive the service. Second, the scheme carries an anti-selling clause of its own: staff of the private dental clinic should not take the initiative to sell their organisation's dental courses or services to an invited person while providing the scaling service.

Time limits: an appointment must be made by telephone with a designated private dental clinic within one month of receiving the invitation SMS, and the scaling service must be completed within three months from the day the SMS is received.

⚠️ The rest of the two footnotes must be read as well. Besides the 12-month rule, footnote 1 first states who gets invited: generally, only civil servants and eligible persons aged 13 or above will be invited. Footnote 2 states a practical consequence of the scheme's narrowness: because Phase Two offers scaling only, anyone who knows they need special care before dental treatment (the example the scheme page gives is antibiotic prophylaxis before scaling) is advised by the scheme page to wait instead for scaling at a government dental clinic.

That is: being invited does not mean the designated private clinic is the right route for you.

⚠️ The number of participating organisations changes, so do not treat this article's figures as live. This article originally gave 17 private dental organisations and 101 clinic entries; a re-check on 2026-08-09 found that they no longer matched — the list page itself had been updated (its latest update record is 6 August 2026), and counting line by line now gives 16 organisations and 95 clinic entries. The 18 district headings, the absence of any clinic entry under Kowloon City, and the 17 districts that actually have clinics all still hold. For the current figures, go to the official page.

---

#The remaining schemes and the CSSA allowance

The age gap is real. The School Dental Care Service ends with Primary Six; the PDCC covers ages 13–17 and states expressly that "anyone who has attained the age of 18 will no longer be eligible". After 18, if you are not an elderly person, not a person with a disability, not on CSSA, not a civil servant or eligible person, not a beneficiary of a Hospital Authority medical fee waiver, and not a user of the designated Social Welfare Department services or the designated homeless services listed above, not one of the government schemes examined here subsidises your scaling.

But the other way round, the CDSP has no age limit. A person of 25 holding a Hospital Authority medical fee waiver (partial) does qualify for the CDSP, with a scaling co-payment of $50 (Category B); if their waiver is a full one they fall into Category A, and the administrative fee for scaling is fully subsidised by the government.

Two further items can be used together: CSSA and the CDSP can be used together (FAQ question 9); and the general public dental sessions and the CDSP can also be used at the same time (question 19).

⚠️ If you are 22, working, drawing no allowance and not a Hospital Authority fee waiver beneficiary: you qualify for none of the eight schemes above. Your real choice is to pay privately, or to queue as a teaching patient at Prince Philip Dental Hospital. This is not an oversight; it is how the system was designed.

#How does the United Kingdom do it? There, the same thing sits in the cheapest charge band

The National Health Service puts scaling in Band 1 — the same price as a routine check-up; but the page states that Band 1 covers the "simple" kind of gum treatment, and that extensive or complex work moves up to Band 2. Hong Kong has nothing corresponding.

The band headings on the NHS dental charges page (page self-dated as reviewed 2025-03-13): Band 1: £27.90, Band 2: £76.60, Band 3: £332.10. The six items of Band 1, complete: examination, assessment and advice; X-rays if clinically needed; fluoride on the surface of the teeth; simple management of gum disease, such as scaling, if clinically needed; moulds of the teeth; and minimal adjustments to dentures or orthodontic appliances [Note 25].

Add the two rules on that page: a mix of treatments from different bands is charged at the highest band; and a mix of treatments from the same band is charged the band fee once. So in the United Kingdom, a check-up plus scaling plus X-rays is charged once, at £27.90.

⚠️ But Band 1 only holds the "simple" kind. The scaling passage on the same page states that scaling is usually included in Band 1, but that extensive treatment, or treatment for complex gum problems, may be charged as a Band 2 treatment; and Band 2's own item list includes "extensive management of gum disease". So the deep scaling described above probably sits in Band 2 in the United Kingdom rather than in the £27.90 cell. Setting Hong Kong's "$17,000 for full-mouth deep scaling" against £27.90 compares the wrong bands.

⚠️ The same NHS page contradicts itself, and this article does not correct it. The band headings say £27.90 / £76.60 / £332.10, but the scaling passage on the same page says "Band 1 (£27.40)" and "Band 2 (£75.30)". Both sets of figures were present on the page on 1 August 2026. This article quotes the band charges in the headings and records the other set from the passage; it does not average them and does not choose between them.

But the United Kingdom is not "ask and receive" either. The last sentence of the same passage: if the dentist says scaling is not clinically necessary, you will have to pay for it privately.

A comparison between the two places has to be put accurately. The NHS expressly places scaling behind a clinical judgement; on the Hong Kong side, three of the five therapeutic subsidy schemes state a dentist's assessment on their pages. So "both places have a clinical gate" holds, on the Hong Kong side, only for three of the schemes.

The real difference is not the gate but whether there is a system behind it for all adults: the United Kingdom has a three-band charging system with scaling in Band 1; Hong Kong has no corresponding system, only a few target schemes drawn by who you are, while the general public dental sessions expressly exclude scaling.

#Why is Hong Kong like this? Three documents give the answer

It is not as simple as "the government will not pay". Historical design, policy direction and workforce supply are all written down in official documents.

One, historical design. The Director of Audit's Report No. 82: government dental clinics "are not for provision of comprehensive dental services for the general public", and since 1947 about 2% of capacity has gone to supplementary emergency services. The absence of a public dental service for the ordinary adult member of the public is not a recent cut but seventy-odd years of system design.

Two, the policy direction expressly chose not to go universal. The final report of the Working Group on Oral Health and Dental Care and the Oral Health Action Plan were published on 6 December 2024. The press release states that the government has been substantially increasing the resources for directly provided or subsidised dental services over the years, with relevant expenditure approaching $1.3 billion in 2023/24, but with the use of resources skewed towards curative treatment instead of prevention; and that the working group recommended shifting the focus from the prevailing treatment-oriented tendency to an approach targeting prevention, early identification and timely intervention [Note 26].

The strategy has a name, from the Director of Health's remarks in the press release of 12 January 2026: the government has adopted the strategy of 「做闊做淺、做窄做深」 — going broad and shallow, and narrow and deep; and the "narrow and deep" half focuses on disadvantaged groups who find dental services harder to obtain, including people in financial difficulty, people with disabilities or special needs, and high-risk groups.

In one sentence: broad and shallow prevention for everyone, narrow and deep subsidy for the disadvantaged — that is an expressly stated strategic choice, and it is not a public dental service for the whole population.

⚠️ There were relevant figures before the strategy was announced, but mind their time span. The Department of Health's press release of 12 January 2026 cites the oral health survey report: the edentulous rate among non-institutionalised elderly people aged 65 to 74 fell markedly from 5.6% in 2011 to 0.9% in 2021, while over the same period the number of teeth rose from 19.3 to 22.8; the same survey also states that more than half of elderly people aged 65 or above using long-term care services have untreated dental caries.

One survey, showing marked improvement over a decade on one side and more than half of one group with untreated caries on the other — the two figures have to be read together; but both belong to a survey period running from 2011 to 2021, which ended before the strategy was announced, and should not be treated as the strategy's effect.

Three, the workforce is the real bottleneck. Department of Health press release of 13 May 2025: more than 65 dentists have newly joined, and the filled proportion of the dentist establishment rose from 69% (on the first of September 2024) to 81%; with the improvement in workforce supply, the Department would from the following month increase the overall disc quota for general public dental sessions by about 30 per cent [Note 27].

The Department of Health's own dentist establishment was only 69% filled in September 2024; recruitment lifted it to 81%; and only then could the general public session quota rise by 30 per cent. How many places there are is not purely a matter of policy stance but of workforce supply.

At specialist level it is tighter still. The Dental Council of Hong Kong's specialist register in periodontology held 52 names as at 28 July 2026 (the other specialties on the same date: orthodontics 75, oral and maxillofacial surgery 73, paediatric dentistry 44, prosthodontics 39, endodontics 23, family dentistry 14, community dentistry 12). For comparison, the Council's 2022 annual report records 47 in periodontology as at 31 December 2022.

Supply-side measures are on the record too: the Legislative Council reply of 21 January 2026 — training places for dental care personnel more than doubled from 95 in the 2023/24 academic year to 220 in 2025/26; and as at the end of 2025 there were 682 registered dental hygienists, with 238 dental therapists working in the Department of Health.

⚠️ If you want to know how long the wait is, remember that the bottleneck is not only money but people. Hong Kong's specialist register in periodontology holds only 52 names, and the Department of Health's own dentist establishment was only 69% filled two years ago.

#What to do next

1. Do not plan around "every six months". The official recommendation is at least one oral check-up a year, with the actual interval set by a dentist according to your oral condition.
2. Do not read a funding cycle as a clinical recommendation. 365 days and 12 months are funding or quota cycles.
3. Before asking the price, ask the unit. Per visit, per quadrant or per course — this is the largest source of price differences.
4. Ask separately about the consultation fee, the periodontal examination and the X-ray. All three are separate lines on the published price lists.
5. If you are quoted for deep scaling, ask about pocket depth. That is the clinical criterion; and the official position on a severe case is that both scaling and root planing are needed.
6. Run through the eight schemes once against your own position. Every one has an eligibility gate; deep scaling is listed as a separate item by only the ODCP and HTC.
7. Do not go to a general public dental session for scaling. The scope expressly excludes it.

Ask these six questions before booking; each corresponds to one of the known sources of price difference above:

1. Is the quote per visit, per quadrant, or per course?
2. Is the consultation fee charged separately?
3. Is the periodontal examination charged separately?
4. Is the X-ray charged separately?
5. Who does it — a dental hygienist or a dental surgeon?
6. Is polishing included? (The point is not to haggle but to see how the other side defines "scaling".)

The government has a related reminder of its own: ask the enrolled healthcare service provider about the service and charging items beforehand; using vouchers or not should not affect the service fees charged.

#Frequently asked questions

Does Hong Kong officially tell people to have their teeth scaled every six months?

No. What the Department of Health publishes is an oral check-up interval, not a scaling interval; for most people it is "an oral check-up once a year will do", and every 6 months or more often is written only for 5 categories of people at high risk or with special needs. The actual frequency is advised by a dentist according to the individual's oral condition.

Does the CDSP's "once every 365 days" mean I should have my teeth scaled once a year?

No. The 365 days is a subsidy cycle, not a clinical recommendation; the PDCC's once a year and PDS2's 12 months are likewise funding or quota cycles. The clinical interval is settled by a dentist according to your oral condition.

Can I have my teeth scaled at a government general public dental session?

No. The scope expressly excludes scaling, offering only relief of pain or extraction, and the English version adds one tooth per visit. There are 11 clinics with general public sessions, all in the morning only; since 30 December 2024 the arrangement has been an online registration ballot, with half the quota reserved for people aged 65 and over.

Is deep scaling subsidised by the government?

Among the schemes examined here, only the Outreach Dental Care Programme for the Elderly (ODCP) and Handy Tooth Care (HTC) list "gum disease treatment" as a separate subsidised item; the CDSP, the PDCC and the general public dental sessions do not. And the Department of Health's position is that a patient with severe gum disease "needs to receive scaling and root planing treatment" — the two are not either/or.

Why are "scaling $980" and "deep scaling $4,250" so far apart?

Because the units differ: the first is per visit and the second is per quadrant of the mouth, and the mouth has four quadrants. Full-mouth deep scaling is $4,250 × 4 = $17,000, plus the periodontal examination at $750 and the consultation fee at $550 = $18,300, before the X-ray at $300.

Can Elderly Health Care Vouchers be used for scaling?

Yes. Dentists are one of the 14 enrolled professional categories for vouchers; question 41 of the voucher FAQ lists "dental check-up, scaling, extraction, filling and so on" as examples of dental services. There is no sub-limit for dental use (the only sub-limit in the whole FAQ is $2,000 every two years for optometry). Vouchers may also be used to pay the CDSP's administrative fee or co-payment.

Prince Philip Dental Hospital charges $100 a course — is that the best value?

The published fee is indeed $100, and the consultation fee is expressly not added. But read it with the hospital's own threshold: it does not provide public dental services; you must go through a screening process assessing your suitability for the designated teaching purposes; waiting times vary from several weeks to several years, and a full course usually requires more visits than treatment from a private dentist. The cheapest route is not the fastest, and whether you get in turns on whether your oral condition suits teaching needs.

I am 22, working and drawing no allowance — is there any subsidy for me?

You qualify for none of the eight schemes — every one has an eligibility gate based on who you are. Your real choice is to pay privately, or to queue as a teaching patient at Prince Philip Dental Hospital. This is how the system was designed: Hong Kong has no public dental service for the ordinary adult member of the public, government dental clinics have since 1947 given only about 2% of capacity to general public sessions, and those sessions exclude scaling.

#Matters on which this article makes no statement

• The clinical position of any Hong Kong professional body. The Hong Kong Dental Association's website carries no publicly available first-hand clinical position document, so this article cannot include any Hong Kong professional body's position on scaling, deep scaling or recall intervals; that source category is unmet. The professional positions in this article come from the British Society of Periodontology, the American Dental Association and the American Academy of Periodontology.
• Effect figures for scaling or deep scaling. None of the sources cited here provides effect data with a denominator and a control group; the highest level that can be cited is the "moderate benefit" rating in the American Dental Association's 2015 guideline. This article therefore gives no figure of the "scaling reduces X%" kind.
• The prevalence of gum disease in Hong Kong. None of the Hong Kong official or academic sources cited here gives a prevalence figure for gum disease or gingivitis in Hong Kong. The 47.2% that appears here is a United States figure whose denominator is United States adults over 30, and it does not apply to Hong Kong.
• An official Hong Kong "scaling interval". There is none. What the Department of Health publishes is only an oral check-up interval. The 365-day and 12-month cycles cited here are all subsidy or quota cycles.
• Absolute figures for general public dental session quotas and attendances after 2024. The Audit Commission's series stops at 2023-24 (up to October 2023); later government documents express the position only in percentages, and this article could find no government document carrying absolute figures, so it makes no estimate.
• The maximum amounts for each item of the CSSA dental treatment expenses allowance. The Social Welfare Department's Comprehensive Social Security Assistance Scheme Guide says only "the maximum amount set by this Department for the dental treatment item concerned", and publishes no figure. The version cited here is that of October 2023; whether a later version exists could not be established, so it is not presented as "2026".
• The fees of Hong Kong NGO dental clinics. A number of NGO and charitable dental bodies that list scaling on their own websites publish no fee schedule, so this article lists no NGO clinic prices.
• Dental fees at the University of Hong Kong Faculty of Dentistry's Institute of Advanced Dentistry multi-specialty clinic and at Tsuen Wan Adventist Hospital. Neither publishes dental fees in readable text, so this article gives no figures for them and does not substitute a paraphrase.
• The ratio of dentists to population. This article does not calculate one; the Dental Council publishes no such ratio, and the "as at" dates of its registers differ. The figure the government itself cites is 0.37 registered dentists per 1,000 people at the end of 2023.
• End dates for the schemes. Except where the issuing body states one (Handy Tooth Care to the end of March 2027; PDS2 to 28 February 2027; the Elderly Health Care Voucher pilot reward scheme for three years, that is 2024 to 2026), this article gives no end date for any scheme.
• The internal contradiction in the NHS charge bands. Not resolved here; both sets of figures are reproduced.
• How many visits periodontal treatment takes. The Department of Health writes "multiple follow-up visits" and the American Dental Association writes "more than one visit"; neither gives a number, and neither does this article.
• The current status of the American Dental Association's 2013 statement. That statement is a press release of 10 June 2013 and is no longer on the association's website. It is identified throughout as the 2013 statement.
• This article recommends no scaling interval or treatment plan for any individual case, and does not compare clinics.

#Notes: the official texts

Where a Chinese source has no English version, the rendering is this site's own, for understanding only, and is not an official version.

[Note 1] Department of Health, Oral Health Education Division, "frequency of oral check-up" page. The Chinese original:

A dentist will advise on how often to have an oral check-up according to the individual's oral condition. For most people, an oral check-up once a year will do, and the following people at high risk or with special needs should have an oral check-up every 6 months or more often: (our translation from the Chinese original)

Chinese original:

「牙科醫生會按個別人士的口腔情況建議檢查口腔的頻率。對一般人來說，可每年檢查口腔一次，而下列高危或有特殊需要的人士就要每6個月檢查口腔一次或更頻密地檢查：」

The English version of the same page:

"For most people, a dental check-up per year is adequate. However, for those with high risk or special needs, a dental check-up every six months or at shorter interval may be necessary."

The opening sentence of the Chinese version has no counterpart in the English. The page's list of people at high risk or with special needs, complete, runs to five categories: people with disabilities; people who have had radiotherapy to the head and neck; smokers; people with severe oral disease; and people with systemic disease.

[Note 2] NICE CG19, "Dental checks: intervals between oral health reviews" (published 27 October 2004):

"1.1.1 The recommended interval between oral health reviews should be determined specifically for each patient and tailored to meet his or her needs, on the basis of an assessment of disease levels and risk of or from dental disease."

"1.1.5 ... The shortest interval between oral health reviews for all patients should be 3 months. ... The longest interval between oral health reviews for patients younger than 18 years should be 12 months. ... The longest interval ... for patients aged 18 years and older should be 24 months."

Paragraph 1.1.8 refers to "as is the case with the current 6-month recall regimen" and states that "there is no guarantee that new disease will not develop between recall visits".

[Note 3] NHS patient page (self-dated "Page last reviewed: 1 April 2025"):

"You may assume you should have a dental check-up every 6 months, but some people may not need to go so often and others may need more frequent checks."

"The time between check-ups can vary from 3 months to 2 years, depending on how healthy your teeth and gums are and your risk of future problems."

[Note 4] American Dental Association statement of 10 June 2013:

"high-risk patients would likely benefit from more frequent dental visits, while low-risk patients may see the same benefits from only one cleaning per year"

"the American Dental Association (ADA) recommends regular dental visits, at intervals determined by a dentist"

[Note 5] St Paul's Hospital Dental Centre adult price list (printed on the page: Effective on 1/4/2026):

Consultation fee (general practitioner) $550 / Scaling $980 / Deep scaling (per quadrant) (the mouth is divided into four quadrants) $4,250 / Periodontal examination $750 / Oral X-ray $300 (our translation from the Chinese original)

Chinese original:

「診金 (全科醫生) $550」 「洗牙 $980」 「深層洗牙(每區域) (口腔分為四區域) $4,250」 「牙周病檢查 $750」 「口腔 X 光片 $300」

The note the price list itself prints:

Note: patients are welcome to ask the dentist about treatment costs and related details before receiving an examination or treatment. (our translation from the Chinese original)

Chinese original:

「備註: 病人在接受檢查或治療前, 歡迎向牙科醫生查詢有關治療費用及相關詳情。」

[Note 6] Prince Philip Dental Hospital teaching patient fee schedule (page self-dated "fees effective from 1 March 2026"):

Consultation fee (per day of attendance) (excluding dental hygiene care and orthodontic treatment) — 50 / Dental hygiene care treatment (all diagnosis and treatment within the same course) — 100 (our translation from the Chinese original)

Chinese original:

「診症費(每日到診計)(接受牙科衞生護理及矯齒治療除外) — 50」 「牙科衞生護理治療(同一療程之所有診斷／治療) — 100」

The private patient fee schedule (page self-dated "Price Range w.e.f. 1 August 2016") has no line for scaling; the closest periodontics line is "Non-surgical Periodontal Therapy (per quadrant) — $3,000 – $8,000", and there is also "Supportive Periodontal Care" $500–$1,500.

[Note 7] Prince Philip Dental Hospital, registration information for teaching patients:

"The Hospital does not provide public dental services."

"You will need to go through a screening process... for assessing your suitability for the designated purposes of teaching..."

"...waiting time... will vary from several weeks to several years... a full course of treatment is likely to be time-consuming and will usually require more visits than if you were to seek treatment from a private dental practitioner."

Department of Health FAQ page: "Prince Philip Dental Hospital does accept a small number of patients for treatment but their oral condition must suit teaching needs."

[Note 8] Chinese University of Hong Kong University Medical Service price list (self-dated "Effective from 1 September 2021"; applicable only to CUHK staff, their families and students):

"Dental Scaling by Dental Hygienist 洗牙(牙齒衛生員) — Terms A 144 / Terms B 96 / Terms C 48 / Student 48" "Dental Scaling / Root Planning by Dental Surgeon 洗牙/牙根整平(牙科醫生) — Terms A 288 / Terms B 192 / Terms C 96 / Student 96"

The spelling "Planning" in the original appears on that price list. "Dental check-up" on the same table is its own line (72 / 48 / 24 / 24). The Department of Health's FAQ page on price differences: "Charges of private dentists are not standardized." The Chinese version: 「這些私家診所的牙科醫生之學歷和專長，與及診所設備和收費都各有不同。」 — the qualifications and areas of expertise of the dentists at these private clinics, and the clinics' equipment and charges, all differ (our translation from the Chinese original). The advice on the same page about asking the price: "You may first compare their prices before making the decision to receive treatment. ... When you are considering the price charged, you should also consider other factors such as treatment method, quality of service etc."

[Note 9] Department of Health, Oral Health Education Division:

Plaque is also calcified by saliva to form calculus. Because the surface of calculus is very rough, it leads to more plaque accumulating, keeping the gums inflamed and possibly worsening into severe gum disease. (our translation from the Chinese original)

Chinese original:

「牙菌膜亦會被唾液（口水）鈣化，形成牙石。由於牙石的表面十分粗糙，因此導致更多牙菌膜積聚，使牙齦持續發炎，甚至有機會惡化成嚴重的牙周病。」

Because brushing cannot remove calculus, you have to see a dentist regularly for check-ups and for scaling to remove it. (our translation from the Chinese original)

Chinese original:

「由於刷牙是不能清除牙石的，因此須定期往見牙科醫生作定期檢查並接受洗牙以去除牙石。」

The definition and procedure of scaling:

Scaling is the removal of plaque, calculus and stains adhering to the tooth surface, restoring the teeth to a clean and smooth state. (our translation from the Chinese original)

Chinese original:

「洗牙是清除黏附在牙齒表面的牙菌膜、牙石和牙漬，使牙齒回復乾淨和平滑。」

The procedure states first the removal of firmly attached calculus with dental instruments or an ultrasonic scaler, then polishing or air-abrasion to remove stains and keep the tooth surface smooth. The American Academy of Periodontology: "Gingivitis is the mildest form of periodontal disease."

[Note 10] Department of Health on root planing:

Root planing is a method of treating severe gum disease… through root planing, the plaque and calculus on the root surface inside the periodontal pocket can be thoroughly cleaned away. (our translation from the Chinese original)

Chinese original:

「牙根刮治是治療嚴重牙周病的一種方法……透過牙根刮治，可以徹底清潔牙周袋內牙根表面的牙菌膜及牙石。」

A patient with severe gum disease needs to receive scaling and root planing treatment. Before treatment, the dentist will establish the state of the gum disease using a periodontal probe, X-ray examination and the like. To reduce the patient's discomfort, the dentist will first inject an anaesthetic at the site concerned, and then thoroughly clean the root surface with dental instruments or an ultrasonic scaler. (our translation from the Chinese original)

Chinese original:

「嚴重牙周病患者需要接受洗牙及牙根刮治的治療。治療前，牙科醫生會利用牙周探針及X-光檢查等確定牙周病的情況。為減輕患者不適，牙科醫生會先在相關位置注射麻醉劑，然後用牙科工具或超聲波洗牙機徹底清潔牙根表面。」

Generally, a full course of treatment for periodontitis includes multiple follow-up visits and regular oral check-ups, and the patient must keep to the appointments so as not to affect progress towards recovery. (our translation from the Chinese original)

Chinese original:

「一般來說，整個治療牙周炎的療程包括多次覆診及定期口腔檢查，患者要切記依期覆診，以免影響康復進展。」

The American Dental Association: "Scaling and root planing may take more than one visit to complete and may require a local anesthetic."

[Note 11] The Department of Health's three grades of management. The Chinese page's wording for the mild grade is 「這樣，輕微牙周病是可以自然痊癒的！」 — in that way, mild gum disease can heal by itself (our translation from the Chinese original); the same passage on the English page reads "Then, the area with mild gum diseasee will heal by itself.", confining healing to "the area", a qualification the Chinese page does not carry, and this article follows the Chinese page. The spelling "diseasee" appears on the official English page. The severe grade:

Scaling to remove calculus; root planing or periodontal surgery to remove the plaque and calculus inside the periodontal pocket and on the root surface; and the dentist will prescribe antibiotics for the patient as the case requires. (our translation from the Chinese original)

Chinese original:

「洗牙以清除牙石；進行牙根刮治或牙周手術以清除牙周袋內及牙根表面的牙菌膜和牙石；牙科醫生會視乎情況處方抗生素供患者服用。」

[Note 12] American Dental Association patient page:

"If gum disease is caught early and hasn't damaged the structures below the gum line, a professional cleaning should do. If the pockets between your gums and teeth are too deep, however, scaling and root planing may be needed."

[Note 13] American Academy of Periodontology on the course of the disease:

"Untreated gingivitis can advance to periodontitis. With time, plaque can spread and grow below the gum line. Toxins produced by the bacteria in plaque irritate the gums and stimulate a chronic inflammatory response in which the body essentially turns on itself, and the tissues and bone that support the teeth are broken down and destroyed. Gums separate from the teeth, forming pockets between the teeth and gums that can become infected. As the disease progresses, the pockets deepen and more gum tissue and bone are destroyed. Eventually, teeth can become loose and may fall out or need to be removed."

The same body on reversibility: "gingivitis is reversible with professional treatment and good at-home oral care"; and on maintenance therapy: "Many patients do not require additional treatment after scaling and root planing. However, the majority of patients will require ongoing maintenance therapy to sustain periodontal health." On the multiple for smoking: "Smokers/smokers can be up to five times or more likely to suffer from gum disease than non smokers."

[Note 14] British Society of Periodontology, clinical guideline explanatory page:

"PMPR stands for 'Professional Mechanical Plaque Removal' and it can be supragingival or subgingival... Subgingival PMPR is an umbrella term and replaces root surface debridement or root planing. It does not mean that what we did before was wrong or unreasonable and it does not change what we use practically. It does mean the death of the term 'scale and polish' which can be misleading to a patient with periodontitis. We are doing much more than just that!"

"A non-engaging patient could be held at step 1 and not move to step 2 until they are demonstrating that they can improve their plaque control. Of course, this is only true if we have educated our patients on the importance of oral hygiene and demonstrated how to do it."

[Note 15] American Dental Association, Nonsurgical Treatment of Chronic Periodontitis Clinical Practice Guideline (2015):

"For patients with chronic periodontitis, SRP showed a moderate benefit, and the benefits were judged to outweigh potential adverse effects. The authors voted in favor of SRP as the initial nonsurgical treatment for chronic periodontitis."

The Department of Health on reactions after scaling:

A gum disease patient may feel mild oral discomfort and have bleeding gums for a few days after scaling; as long as oral hygiene continues to be attended to, the discomfort and bleeding will gradually disappear and the gums will return to health. (our translation from the Chinese original)

Chinese original:

「牙周病患者於洗牙後的幾天內可能感到口腔輕微不適及有牙齦出血的現象，只要繼續注意口腔衛生，口腔不適及牙齦出血的現象就會逐漸消失，牙齦亦會回復健康。」

On home care:

Root planing must be accompanied by good oral hygiene care for a good result… a person who smokes must give up smoking, because smoking makes gum disease hard to heal. (our translation from the Chinese original)

Chinese original:

「牙根刮治必須配合良好的口腔衛生護理，才能達至良好效果……有吸煙習慣的人士必須戒煙，因為吸煙會使牙周病難以痊癒。」

The American Dental Association's MouthHealthy page cites research of July 2015 in the Journal of the American Dental Association: "Chronic periodontitis affects 47.2% of adults over 30 in the United States."

[Note 16] Chapter 2 of the Director of Audit's Report No. 82 (published 24 April 2024):

"As of February 2024, the Department of Health operated 43 government dental clinics. These 43 government dental clinics are not for provision of comprehensive dental services for the general public. However, since 1947, the Government uses a small fraction (around 2%) of the service capacity of the dental clinics to provide a limited scope of supplementary emergency dental services to the general public."

[Note 17] Department of Health, general public dental session page (page self-dated 30 July 2026):

The emergency services provided at general public dental sessions include relief of pain or tooth extraction, but not fillings, scaling, dentures, removal of bridges and the like; extraction before orthodontic treatment is also outside the scope of service. (our translation from the Chinese original)

Chinese original:

「牙科街症提供的緊急服務包括止痛或脫牙，但不包括 補牙、洗牙、鑲牙、拆除牙橋 等服務，此外箍牙前的脫牙也不在服務範圍內。」

The English version of the same passage reads "relief of pain and tooth extraction (one tooth per visit)", adding the limit of one tooth per visit. The charges:

From 1 January 2026, the general public dental session service is free for eligible persons; the consultation fee for a person who is not eligible (including extraction and other emergency oral surgery) is HK$850 (our translation from the Chinese original)

Chinese original:

「由2026年1月1日起，為符合資格人士提供的牙科街症服務為免費；非符合資格人士之診症費用 (包括拔牙及其他緊急的口腔手術) 為港幣$850元」

The three limbs of the definition of "eligible person": a person holding a Hong Kong identity card issued under the Registration of Persons Ordinance (Cap. 177) (other than one issued on the strength of an expired or invalid permission to land or remain); a child under 11 who is a Hong Kong resident; or another person recognised by the Director of Health. The clinic list page (page self-dated the first of May 2025) names 11 clinics with general public sessions.

[Note 18] The same page on how a disc is obtained:

The online registration system for general public dental sessions came into service on 30 December 2024. On the same day the "preliminary registration" arrangement for general public dental session services stopped, and members of the public no longer have to queue at the dental clinic concerned for a disc. Online registration for the ballot runs from 6 o'clock to half past 11 in the morning, so as to make registration convenient for members of the public in need of emergency dental services. If the following day is a Saturday or a public holiday, the registration system will not accept registration. (our translation from the Chinese original)

Chinese original:

「牙科街症網上登記系統（登記系統）已於二零二四年十二月三十日投入服務。同日，牙科街症服務的「初步登記」安排已停止，市民無須再前往有關牙科診所排隊取籌。網上登記抽籤時間，由早上六時至上午十一時三十分，以便利有需要獲取緊急牙科服務的市民登記。如翌日為星期六或公眾假期，登記系統將不接受登記。」

The two allocation rules:

To give particular care to elderly people in need, half the quota is reserved for a priority ballot for those aged 65 or above. The Department of Health sets aside 5 per cent of the first-round ballot quota for people who have registered repeatedly for a general public dental session within the past 30 days without successfully being allocated a service place. (our translation from the Chinese original)

Chinese original:

「為了特別照顧有需要的長者，一半的名額會預留給65歲或以上的長者優先抽籤」 「衞生署劃出百分之五的首輪抽籤名額，分配予過去30日內多次登記牙科街症但未能成功獲發服務名額的人士」

Anyone needing help to register may attend in person between half past 8 and half past 11 in the morning at a dental clinic with general public sessions, where staff on site will assist.

[Note 19] The Audit Commission report's quota series (source: Department of Health records):

"From 2014-15 to 2018-19, the number of discs for allocation (i.e. disc quota) of the 11 government dental clinics was about 40,000 a year. From 2018-19 to 2022-23, while the disc quotas decreased from 40,322 to 20,337, the disc allocation rate (i.e. the percentage of disc quota allocated) increased from 92.3% to 99.2%."

Government press release of 26 June 2025: "the average utilisation rate of the GP sessions is as high as 99 per cent".

[Note 20] The assessment wording on the three scheme pages. The CDSP:

After assessment by the attending registered dentist of the NGO selected by the government, a participant may, if the case is suitable, receive the following services: (our translation from the Chinese original)

Chinese original:

「經政府選定的非政府組織主診註冊牙科醫生評估後如情況合適，計劃參加者可獲以下服務：」

The heading of the fee table also reads 「資助服務範圍 (經牙科醫生評估)」 — subsidised scope of service (after assessment by a dentist) (our translation from the Chinese original). The ODCP:

If the outreach team's dentist assesses that an elderly person has a dental treatment need, they will provide treatment on site or arrange a referral to a designated dental clinic for further treatment. (our translation from the Chinese original)

Chinese original:

「若外展隊牙醫評估後認為長者有牙科治療需要，他們會為長者提供實地治療或安排轉介至指定的牙科診所作進一步治療。」

PDS2:

The dentist at the private dental organisation will also make an assessment on the day of scaling to decide whether the invited person is suitable to receive the scaling service. (our translation from the Chinese original)

Chinese original:

「私營牙科醫療機構的牙醫也會在洗牙當日作出評估，決定獲邀人士是否適合接受洗牙服務。」

The PDCC's subsidised scope is a list of six items and the HTC's a list of nine; neither list is preceded or followed by any gate-like sentence.

[Note 21] The CDSP's subsidised scope at launch (press release of 26 May 2025):

Oral examination; medication to relieve toothache (if needed); X-ray examination; filling or extraction, with each tooth counting as one "filling or extraction quota". (our translation from the Chinese original)

Chinese original:

「口腔檢查；緩解牙齒疼痛的藥物（如需要）；X光檢查；補牙或拔牙，以每一顆牙齒為一個「補牙或拔牙配額」。」

The press release of 17 December 2025:

From the first of January next year, the Community Dental Support Programme will expand its scope of service, adding scaling, root canal treatment, removal of bridges and crowns, and the fitting of removable dentures (our translation from the Chinese original)

Chinese original:

「明年一月一日起，『社區牙科支援計劃』（支援計劃）會擴大服務範圍，新增洗牙、根管治療（杜牙根）、移除牙橋和牙冠及鑲配活動假牙項目」

It also states:

Each participant may receive one scaling service every 365 days. (our translation from the Chinese original)

Chinese original:

「每名計劃參加者每365日可獲一次洗牙服務」

[Note 22] The CDSP scheme page's subsidised scope:

Every 180 days: oral examination / medication to relieve toothache (if needed) / X-ray examination / filling or extraction, each tooth counting as one "filling or extraction quota" (up to three "filling or extraction quotas") / removal of bridges and crowns (one bridge or two crowns) (our translation from the Chinese original)

Chinese original:

「每180日：口腔檢查／緩解牙齒疼痛的藥物（如需要）／X光檢查／補牙或拔牙，以每一顆牙齒計算為一個『補牙或拔牙配額』（最多可獲三個『補牙或拔牙配額』）／移除牙橋和牙冠（一條牙橋或兩個牙冠）」

Every 365 days: scaling / root canal treatment (one tooth) (our translation from the Chinese original)

Chinese original:

「每365日：洗牙／根管治療（杜牙根）（一顆牙齒）」

Every 5 years or more: fitting of removable dentures (each participant may receive the service at most twice, with at least 5 years between them) (our translation from the Chinese original)

Chinese original:

「每5年或以上：鑲配活動假牙（每名計劃參加者可接受最多兩次服務，每次須相隔5年或以上）」

FAQ question 14:

At this stage, an eligible person may complete all treatment at one visit or over several visits as needed, and all treatment must be completed within 180 days. (our translation from the Chinese original)

Chinese original:

「現階段，合資格人士可一次或按需要分多次完成所有治療，而所有治療須於180天內完成。」

The way sets of dentures are counted, in the footnote to the Chinese page:

The co-payment is counted per set of dentures (meaning the upper or the lower jaw). Fitting removable dentures for both the upper and the lower jaw counts as two sets. (our translation from the Chinese original)

Chinese original:

「共付額以每副假牙（指上顎或下顎）計算。同時鑲配上及下顎活動假牙視為兩副。」

FAQ question 26 confirms the same method of counting. The condition on the introduction page:

A participant will be provided with the subsidised service of fitting removable dentures only if fewer than twenty teeth remain and a dentist assesses that they have difficulty eating or chewing which the fitting of removable dentures would effectively restore. (our translation from the Chinese original)

Chinese original:

「如計劃參加者剩餘少於二十顆牙齒，並獲牙醫評定有進食或咀嚼困難且能透過鑲配活動假牙而有效修復進食或咀嚼功能，才會獲提供鑲配活動假牙的資助服務。」

The FAQ page words the same rule as 「如計劃參加者剩餘少於二十顆真牙齒……」 — if a participant has fewer than twenty natural teeth remaining (our translation from the Chinese original) — so the two pages differ, and this article has no information with which to judge which is right. (The English version of that page has a footnote inconsistent with the figures in its table, and this article does not cite the English footnote.)

[Note 23] The three limbs of CDSP eligibility, from the scheme page: holding a valid Hong Kong identity card or Certificate of Exemption; and being a current beneficiary or recipient of any one of — the Social Welfare Department's Old Age Living Allowance; the Department's Community Care Service Voucher Scheme for the Elderly (co-payment level two); the Department's Integrated Home Care Services for frail elderly persons or Home Support Services (fee level one or two, co-payment level one or two); being a Hospital Authority patient granted a medical fee waiver (full or partial); or being a homeless person applying with the help of a social worker at a designated NGO (who must be a user of one of four Social Welfare Department services: an urban hostel for single persons, a temporary shelter, an integrated service team for street sleepers, or support services for the marginalised, street sleepers only); and being registered with eHealth. FAQ question 4:

No. A person of any age may apply to join the scheme so long as they meet the eligibility criteria. (our translation from the Chinese original)

Chinese original:

「沒有。任何年齡人士，只要符合資格便可申請參加計劃。」

Legislative Council written reply of 21 January 2026: "Currently, 32 NGOs are participating in the CDSP, providing over 80 service points... As at December 31 last year, over 5 700 participants had used the service."

[Note 24] Department of Health PDS2 Chinese page (page self-dated 28 July 2026):

The service period of Phase Two of the pilot scheme will be extended to 28 February 2027. (our translation from the Chinese original)

Chinese original:

「先導計劃第二期的服務期會延長至2027年2月28日。」

Phase Two of the pilot scheme continues to run on a public-private partnership model, with booking arrangements similar to those of Phase One; with the extended service period, it is expected that a total of about 200 000 civil servants and eligible persons can be arranged to receive one scaling service at a private dental clinic. (our translation from the Chinese original)

Chinese original:

「先導計劃第二期繼續以公私營協作模式進行，預約安排與先導計劃第一期相若，延長服務期後，預計可為合共約20萬名公務員及合資格人士安排於私營牙科診所提供一次洗牙服務。」

Under Phase Two of the pilot scheme, the government will subsidise eligible participants to receive one scaling service at a private dental clinic only, and will not bear the cost of any other treatment agreed between a participant and a dental organisation or clinic. (our translation from the Chinese original)

Chinese original:

「在先導計劃第二期下，政府只會資助合資格參與計劃的人士接受私營牙科診所提供一次洗牙服務，不會承擔參與計劃人士與牙科機構／診所之間協定的任何其他治療費用。」

The anti-selling clause:

Staff of the private dental clinic should not take the initiative to sell their organisation's dental courses or services to an invited person while providing the scaling service. (our translation from the Chinese original)

Chinese original:

「私營牙科診所的人員不應在提供洗牙服務時主動向獲邀人士推銷其機構的牙科療程或服務。」

The time limits: an invited person 「須於收到邀請電話短訊後一個月內，致電先導計劃第二期下的任何一間指定私營牙科診所預約洗牙服務」 — must telephone any designated private dental clinic under Phase Two within one month of receiving the invitation SMS to book the scaling service — and 「洗牙服務必須於收到邀請電話短訊當天起計三個月內完成」 — the scaling service must be completed within three months from the day the invitation SMS is received (our translation from the Chinese original). Footnote 1:

A person who has received a scaling service at a government dental clinic, or under any pilot scheme for civil servants and eligible persons, within the past 12 months will be invited in a later batch only after those 12 months have expired. (our translation from the Chinese original)

Chinese original:

「過去12個月內曾接受政府牙科診所或任何為公務員及合資格人士提供的先導計劃下洗牙服務的人士，需待其接受服務12個月屆滿後才會分批獲邀。」

[Note 25] NHS dental charges page (self-dated "Page last reviewed: 13 March 2025"), the six items of Band 1 in full:

"examination, assessment and advice (a routine dental appointment) / X-rays, if clinically needed / putting fluoride on the surface of your teeth / simple management of gum disease, such as scaling (a thorough clean of your teeth and gums), if clinically needed / moulds of your teeth, for example to see how your teeth bite together / minimal adjustments to false teeth (dentures) or orthodontic appliances, such as braces – for example, smoothing rough parts or tightening clasps"

The two rules: "If you need a mix of treatments from different bands, you'll pay for the cost of the highest band of treatment you're having." and "If you need a mix of treatments from the same band, you'll only pay the band charge once." The scaling passage: "Scaling is usually included in Band 1 (£27.40), but extensive treatment, or treatment for complex gum problems may be charged as a Band 2 (£75.30) treatment." — the £27.40 and £75.30 in that passage are inconsistent with the £27.90 and £76.60 of the page's band headings, and both sets were present on the page on 1 August 2026; this article reproduces both and does not choose between them. The last sentence of the same passage:

"If the dentist says scaling is not clinically necessary, you'll have to pay for it privately."

[Note 26] Press release announcing the Oral Health Action Plan (6 December 2024):

"the Government has been substantially increasing the amount of resources for directly provided or subsidised dental services over the years, with relevant expenditure approaching $1.3 billion in 2023/24, but the utilisation of resources has skewed towards curative treatment instead of prevention."

The working group recommended "shifting the focus... from the prevailing treatment-oriented tendency to an approach targeting prevention, early identification, and timely intervention". The Director of Health's remarks of 12 January 2026:

In December 2024 the government published the final report of the Working Group on Oral Health and Dental Care together with an action plan, adopting the strategy of "going broad and shallow, and narrow and deep" in developing the oral health and dental care service system. Within it, "narrow and deep" focuses on disadvantaged groups who find dental services harder to obtain, including people in financial difficulty, people with disabilities or special needs, and high-risk groups, providing them on a public or subsidised model with the dental services they need, both preventive and therapeutic oral health and dental care. (our translation from the Chinese original)

Chinese original:

「政府在二○二四年十二月公布口腔健康及牙科護理工作小組總結報告及行動計劃，採納『做闊做淺、做窄做深』的策略發展口腔健康及牙科護理服務體系。當中，『做窄做深』聚焦為較難獲得牙科服務的弱勢社群，包括有經濟困難人士、有殘疾或特殊需要人士及高風險群組，以公營或資助模式提供必需的牙科服務，包括預防性和治療性的口腔健康及牙科護理服務。」

The same words are split into two sentences in the press release of 20 March 2026, using ordinary 「」 rather than the white corner brackets 『』. The press release of 12 January also cites the oral health survey report:

The edentulous rate among non-institutionalised elderly people aged 65 to 74 fell markedly from 5.6% in 2011 to 0.9% in 2021, while over the same period the number of teeth rose from 19.3 to 22.8. (our translation from the Chinese original)

Chinese original:

「65至74歲非居於院舍長者的無牙比率從二○一一年的5.6%顯著下跌至二○二一年的0.9%，同期，牙齒數目則由19.3顆上升至22.8顆。」

[Note 27] Department of Health press release of 13 May 2025:

Progress has also been made in the Department of Health's recruitment of dentists, with more than 65 dentists newly joining… the filled proportion of the serving dentist establishment has risen from 69% (on the first of September 2024) to 81% at present. With the improvement in workforce supply, the Department of Health will from next month increase the overall disc quota for general public dental sessions by about 30 per cent. (our translation from the Chinese original)

Chinese original:

「衞生署的牙醫招聘工作亦取得進展，新入職的牙醫人數超過65名……在職牙醫的實際人手比例由69%（二○二四年九月一日）提升至現時的81%。在人手供應有所提升的情況下，衞生署將由下月起增加牙科街症服務整體派籌名額約三成。」

The Dental Council of Hong Kong's specialist registers as at 28 July 2026: periodontology 52, orthodontics 75, oral and maxillofacial surgery 73, paediatric dentistry 44, prosthodontics 39, endodontics 23, family dentistry 14, community dentistry 12; the Council's 2022 annual report records 47 in periodontology as at 31 December 2022. Legislative Council reply of 21 January 2026: training places "more than doubled from 95 in 2023/24 academic year to 220 in 2025/26 academic year"; and as at the end of 2025 there were 682 registered dental hygienists, with 238 dental therapists working in the Department of Health. The reminder on the Elderly Health Care Voucher use page:

"Ask the enrolled healthcare service provider about the service and charging items beforehand. Using vouchers or not should not affect the service fees charged."
