Last updated 9 October 2026 — by Adrian Tan, SDM. Marketing guidance, not legal advice. Section and clause numbers refer to the Dental Registration Act 1999 and the Healthcare Services (Advertisement) Regulations 2021 as shown on Singapore Statutes Online, and to the Singapore Dental Council’s Ethical Code and Ethical Guidelines (2018 edition, updated 2019), as at October 2026. Check with the SDC, MOH or a lawyer before relying on any point.
Dental marketing in Singapore looks, at first glance, like any other local-services category. Patients search “dentist near me”, compare Google reviews, scroll Instagram for smile makeovers and click on “invisible braces” ads. Clinics want to compete on all of those channels, and many hand the job to agencies used to selling gyms, salons and restaurants.
That is where problems start. A dental clinic’s advertising is governed by two rulebooks at once: the Healthcare Services (Advertisement) Regulations 2021, which bind every licensed healthcare provider, and the Singapore Dental Council’s Ethical Code and Ethical Guidelines (ECEG), which bind every dentist personally and are in several places stricter. Behind both sits the Dental Registration Act, which controls who may call themselves a dentist or a specialist at all.
This guide is written for clinic owners and the marketers who work with them. It sets out the dental-specific rules, where the two rulebooks differ, and how they apply to the things dental marketing actually runs on: specialist titles, whitening and aligner promotions, reviews, before-and-after photos and price ads. For the general healthcare advertising rules that apply to all clinics, see our guide to digital marketing for healthcare providers in Singapore.
The rules at a glance
| Common dental ad | Allowed? | Rule |
|---|---|---|
| “Our orthodontist” for a dentist not on the specialist register | No | Dental Registration Act s 39(1); discipline under s 50 |
| Before-and-after smile photos on the website or social media | No | HCS (Advertisement) Regs reg 5(1)(d); ECEG 5.4.6(b) |
| “Instant whitening” or “straight teeth in 2 weeks” | No | Soliciting under reg 5(1)(g), per MOH’s own examples |
| “Free consultation”, “50% off scaling”, “promo ends Sunday” | No | Reg 15; reg 5(1)(g); ECEG 5.4.6(e) |
| Patient testimonials in ads or SEO review packages | No | ECEG 5.4.6(f) and the SDC’s 2020 advisory |
| Exact final price for a named procedure | Yes | MOH Q&A: exact price only, no “from” or “was/now” |
| Factual list of services, qualifications and location | Yes | ECEG 5.4.6(a); reg 5(1)(a) |
Who may call themselves a dentist, and a specialist
The protected titles
Under section 33(1) of the Dental Registration Act 1999, only a registered dentist with a practising certificate may use the titles “dentist”, “dental surgeon”, “registered dentist”, “qualified dentist”, “doctor of dental surgery”, “professor of dentistry” or “surgeon dentist”, or any title implying the person is qualified to treat dental disorders. Practising dentistry without registration is a separate offence under s 29. Both are punishable under s 35 with a fine of up to S$25,000, rising to S$50,000 and/or six months’ jail for a repeat conviction. Employers and partners can be liable too (s 30), and a dentist who lets an unregistered person practise on premises they control commits an offence under s 31.
Section 2 defines dentistry broadly, including “the performance of any procedure… on or of the human teeth or jaws or associated structures”. That matters for the cosmetic services sold through social media, as the enforcement section below shows.
Specialist claims
Singapore recognises eight dental specialties: endodontics, oral and maxillofacial surgery, orthodontics, paediatric dentistry, periodontics, prosthodontics, dental public health and, since 1 July 2025, special care dentistry. A dentist becomes a specialist only by registration on the Register of Specialists, on the certificate of the Dental Specialists Accreditation Board.
Section 39(1) says a dentist not on that register must not practise under a specialist title, imply specialist status, or “advertise or hold himself or herself out as a specialist”. Section 38 adds that dentists may display only qualifications entered in the register or approved by the Council, and s 38(7) makes clear that “use” covers cards, signboards, circulars and any notice, which in practice includes websites and social media profiles. Breaches go to the SDC’s Disciplinary Committee under s 50, which can strike a dentist off, suspend them for three months to three years, or impose a penalty of up to S$50,000.
For marketers, the risk is in everyday copy rather than formal titles:
- “Braces specialist”, “implant expert” or “our orthodontist” describing a general dentist who does a lot of orthodontic work.
- “Specialist clinic” for a practice where only some dentists are specialists.
- Overseas master’s degrees or certificates listed after a name when the SDC has not approved them.
- “Aesthetic dentistry specialist”. Facial aesthetics is not a recognised specialty, and ECEG 5.1.1.4 says dentists must not imply they are specialists in it.
The safe pattern is to describe what a dentist does (“provides orthodontic treatment, including clear aligners”), and to use “specialist” only for dentists whose names appear on the specialist register, with the specialty named exactly.
Two rulebooks: HCSA and the Dental Council
Outpatient dental services moved under the Healthcare Services Act 2020 on 26 June 2023, so every dental clinic is now an HCSA licensee. Under HCSA s 31 only the licensee, or someone acting on its authority, may advertise a licensable service, and the Healthcare Services (Advertisement) Regulations 2021 set out what an ad may contain. Penalties under s 31(3) reach S$20,000 and/or 12 months, plus S$1,000 a day for a continuing offence, and agencies acting for the licensee can be separately liable.
The Regulations apply to any ad accessible from Singapore (reg 3) and require, among other things (reg 5(1)), that ads are accurate and substantiable, make no comparisons and use no superlatives, contain no before-and-after images, carry no reviews or testimonials except as reg 14 allows, and do not solicit or encourage use of the service. Reg 6 limits off-premises advertising to listed media such as newspapers, directories, brochures and the internet, and reg 15 bans advertising gift or benefit programmes.
The ECEG sits on top. It has been a condition of practising-certificate renewal since 2025 that dentists complete an ethics self-assessment on it, and in at least three areas it goes further than the Regulations.
Reviews and testimonials: the biggest gap
Under HCSA reg 14, a licensee may show patient reviews on its own premises, website or social media if the patient gave them directly, was not paid or rewarded, and the review has not been substantively changed. Many clinic marketers read that as permission to feature Google reviews on the website.
For dentists, the ECEG says otherwise. Clause 5.4.6(f) states that “testimonials are subjective and must not be used in advertising on any media where the dental practitioner has any control over the content”, and dentists must not ask or induce anyone to write positive testimonials. In a 24 November 2020 advisory, the SDC told dentists to refrain from SEO platforms that use patient feedback or ratings, and warned that paying for such packages may be read as agreeing to the use of testimonials.
No official source reconciles the two, so our reading is that a dental clinic should follow the stricter Dental Council position: do not embed review widgets or quote patients on the website, do not run review-generation campaigns, and do not buy “reputation” packages. Reviews that patients leave on Google of their own accord are a different matter, because the dentist does not control them, but they should not be pulled into the clinic’s own marketing.
Group practices cannot hide behind the brand
ECEG 5.4.5 says dentists linked to a healthcare organisation are responsible for its marketing output, and “lack of awareness” is not a defence. In a dental group, every dentist whose name or profile appears is exposed if the group’s Instagram account runs a non-compliant promotion. Clinic managers should give dentists sight of campaigns before they go live.
What a dental ad may and may not say
Read together, ECEG 5.4.1-5.4.6 and HCSA reg 5 describe a very particular style. Information must be factual, accurate and verifiable, and must not be “extravagant, misleading, sensational, persuasive, comparative or disparaging”. Clinic websites should give neutral information about registered qualifications, experience and areas of practice (5.4.6(a)), and must avoid content that arouses strong emotion, plays on self-esteem or body image, or uses “glitz, glamour, style, famous locations, associations with celebrities” (5.4.6(c)-(d)).
Soliciting: MOH’s own dental examples
MOH has published examples of wording it treats as soliciting under reg 5(1)(g). Two are dental: “instant / immediate teeth whitening” and “straight teeth in 2 weeks”. The same list covers “as low as” and “lowest prices”, packages tied to a discount, validity periods, and words such as “discount”, “interest free”, “promotion”, “offer”, “complimentary” or “free”. Group-buy deals, giveaways, lucky draws, redemption with miles or points, and showing an instalment amount without the total price are also out.
Prices
Clinics may advertise prices, but only the exact, final price: no “from S$X”, no “was S$800, now S$500”. Payment plans and package prices may be raised only at the point of payment. ECEG 5.4.6(e) adds that free or discounted examinations and treatments are not allowed outside legitimate non-commercial health promotion, and nor are tie-ups with unrelated commercial entities “(such as credit cards)”, gifts, or offering treatment as a prize.
CHAS clinics have one extra price-display duty. Since 1 October 2025, CHAS dental clinics must display MOH’s fee benchmarks for 18 CHAS dental procedures prominently next to their price lists. There is no published rule on advertising CHAS subsidies themselves, but a headline like “only S$X after CHAS” reads as a price-led inducement, so we would not use it. The SDC has disciplined dentists over CHAS claims (a 16-month suspension in July 2024 and a S$10,000 fine plus four-month suspension in May 2026), which is a reason to keep subsidy messaging plain and accurate.
Rewriting a typical promotion
| Common copy | Problem | Compliant alternative |
|---|---|---|
| “Brighter smile in ONE hour! Whitening promo S$299 (U.P. S$499)” | “Instant” result claim, promotion, was/now price | “In-clinic teeth whitening, S$299. Suitability is assessed at consultation.” |
| “Singapore’s most trusted invisible braces specialist” | Superlative; specialist title if not registered | “Dr [name] provides orthodontic treatment, including clear aligners.” Use “orthodontist” only if on the specialist register. |
| “FREE consultation + scaling for new patients this month” | Free offer, time limit, inducement | “New patient consultations available. Consultation fee: S$[exact amount].” |
| Carousel of before-and-after smiles with patient quotes | Before-and-after images and testimonials | Explain the treatment process with diagrams or photos of the clinic and equipment |
| “Pay with [bank] card, get 10% off implants” | Credit-card tie-up, discount | Omit; payment options can be discussed at the clinic |
Teeth whitening: who may offer it and how
Teeth whitening is the most heavily advertised cosmetic dental service and the one with the clearest product rule. HSA’s position, restated in a 28 May 2026 safety article, is that tooth-whitening products sold directly to consumers may contain at most 0.1% hydrogen peroxide. Products above that level may only be used by or supplied through registered dentists, and should be labelled “Not for direct sale to the public” or “For supply only through a qualified dental practitioner”. HSA described a case in which a 4% hydrogen peroxide kit was sold online without those warnings; the supplier was told to supply registered dentists only, and the listings were removed.
For beauty salons, the 2015 MOH and SDC guideline on tooth whitening by non-dental professionals says a non-dentist using a product at or below 0.1% does not breach any Act, and that the Dental Registration Act does not categorically treat whitening as dentistry. A salon using a stronger product would have obtained it unlawfully, and MOH and the SDC have said they take a serious view of dentistry performed by non-dentists.
Three practical consequences for marketing:
- A dental clinic advertising professional whitening is advertising a licensable dental service, so the HCSA rules apply: no “instant” results, no before-and-after shots, no promotional pricing.
- A salon or e-commerce seller should not imply its whitening matches a dentist’s, and must not use dental titles to describe its staff (s 33).
- Online sellers of whitening kits need to check the product’s hydrogen peroxide concentration before listing it at all.
Clear aligners and teledentistry
Aligner marketing often promises treatment with minimal clinic visits. No MOH, SDC or HSA position specific to direct-to-consumer aligners has been published, but the existing rules already shape what can be offered:
- A first consultation cannot be remote. ECEG 5.1.1.5 says a new relationship with a patient should not be established through electronic means, and no consultation fee may be charged for that first contact. Remote adjustment of treatment is allowed only after an in-person relationship, diagnosis and start of treatment (5.1.1.6).
- Remote dental service needs another mode. Under HCSA, remote provision of outpatient dental service can only be offered together with another mode of service delivery, such as a clinic.
- Brands need the clinic’s approval. MOH says a non-licensee, such as an aligner or device brand, may say it collaborates with a dental clinic, but to advertise the clinic’s service it needs the clinic’s prior approval and must follow the Regulations.
- Speed claims are out. “Straight teeth in 2 weeks” is MOH’s own example of soliciting.
An aligner campaign that works within these rules sells the in-clinic assessment, explains the process and the dentist’s role, and avoids promising timelines or results.
Enforcement: illegal dentistry on social media
The most visible enforcement in recent years has targeted unregistered providers rather than licensed clinics. Speaking at the International Dental Exhibition and Meeting on 17 April 2026, HSA’s chief executive said MOH and HSA had investigated about 20 cases of unlawful dental practice between 2021 and 2025, mostly involving cosmetic procedures such as veneers and braces, including treatment in hotel rooms, a beauty salon and a home. He said surveillance includes social-media promotion. In April 2024 a Malaysian woman who marketed herself as a dentist and fitted veneers and braces in Singapore hotel rooms was fined S$2,500 under the Act, as reported by Free Malaysia Today.
For licensed clinics, the lesson is about adjacency. A clinic that partners with influencers, salons or “smile studios” to promote veneers or aligners needs to know who is actually treating patients, because promoting an unregistered provider’s work as dentistry is exactly what regulators are looking for.
Channel notes
- Meta. Meta’s Health and Wellness policy permits cosmetic before-and-after images and requires cosmetic-procedure ads to target people aged 18 and over. Singapore law is stricter: before-and-after images are banned by reg 5(1)(d) and ECEG 5.4.6(b), and platform approval is no defence.
- Google. Health is a sensitive category in Google’s personalised advertising policy, so customer-list and lookalike targeting are not available for health ads. Search campaigns built on service and location keywords (“root canal treatment Tampines”) remain the core channel. Our guide to SEO for clinics in Singapore covers the organic side.
- Video. Patient story videos are testimonials under the ECEG, so clinic videos should explain procedures, equipment and the dentist’s approach instead. Our testimonial video guide explains why the format that works for other businesses does not suit dentistry.
- Brochures and handouts. Brochures must carry a date (reg 6(5); ECEG 5.4.4), and free handouts and push messages need prior written consent (reg 6(4)). ECEG 5.4.4 also rules out unsolicited visits, calls and active distribution of literature.
- Links. A clinic website must not link to non-compliant sites (reg 16), and the ECEG says it must not link to commercial companies or patient testimonies.
Conclusion
Dental advertising in Singapore rests on three layers: the Dental Registration Act controls titles and specialist claims, the Healthcare Services (Advertisement) Regulations control what a licensed clinic’s ads may contain, and the Dental Council’s Ethical Code adds stricter personal duties on reviews, offers and group marketing. The result is a factual, unpromotional style that most generic marketing playbooks break on day one. Clinics that compete on clear information, accurate specialist status, exact prices and strong local search visibility are working with those rules, not against them.

Aesthetic clinics work under the same advertising regulations, plus a separate SMC rulebook that lists which procedures doctors may offer and bans titles such as “aesthetic physician”. We cover it in our guide to aesthetic clinic advertising rules in Singapore.
Frequently asked questions
Can a dental clinic in Singapore show before-and-after photos?
Not in advertising. The Healthcare Services (Advertisement) Regulations ban before-and-after and after-only images in ads, and the Dental Council’s Ethical Code bans them in the public domain. They may be shown to a patient during a consultation.
Can a general dentist advertise as a braces or implant specialist?
No. Under section 39 of the Dental Registration Act, only dentists on the Register of Specialists may advertise or hold themselves out as specialists. A general dentist can describe the treatments they provide, but not use a specialist title or imply specialist status.
Can dental clinics post patient reviews on their website?
HCSA reg 14 allows unpaid, unedited reviews on a clinic’s own site, but the Dental Council’s Ethical Code bars testimonials on any media the dentist controls, and a 2020 SDC advisory warned against review-based SEO packages. Dental clinics should follow the stricter Council rule.
Can a dental clinic advertise promotions or free consultations?
No. Free or discounted treatments, time-limited offers, gifts and credit-card tie-ups are barred by the Dental Council’s Ethical Code, and MOH treats words such as “promotion”, “discount” and “free” as soliciting. Clinics may state the exact, final price of a procedure.
Is teeth whitening at a beauty salon legal in Singapore?
A salon using a product with no more than 0.1% hydrogen peroxide does not breach any Act, according to MOH and SDC guidance. Stronger products may only be used by or supplied through registered dentists, and salons must not describe their staff as dentists.
Can clear aligner treatment start with an online consultation?
Not as a new dentist-patient relationship. The Dental Council’s Ethical Code says a new relationship should not be established through electronic means, and remote adjustment of treatment is allowed only after in-person diagnosis. Remote dental services must be offered alongside a clinic.
