UK dental advertising must be accurate, evidence-based and not misleading. GDC guidance requires dental professionals to present services, qualifications and expected outcomes honestly. ASA and CAP rules require objective claims to be supported, before-and-after images to be genuine and representative, and cosmetic promotions to avoid irresponsible targeting or exaggerated results. These duties apply across websites, social media, paid ads and third-party marketing.
This guide turns the main rules into practical website and campaign checks. It is general information, not legal advice. Practices should check the current source guidance and obtain specialist advice where a claim or campaign creates uncertainty.
Who regulates dental advertising in the UK?
The General Dental Council regulates dental professionals and sets professional standards, including guidance on advertising. The Advertising Standards Authority applies the CAP Code to non-broadcast advertising and the BCAP Code to broadcast advertising. Consumer protection, medicines, data protection, platform and professional rules can also apply depending on the campaign.
A practice should not treat these as separate boxes. A treatment claim may need to be professionally appropriate under GDC guidance, adequately supported under advertising rules, compatible with medicines law and presented without exploiting a patient's vulnerability.
The safest operating principle is simple: say what is true, support objective claims, explain important limits and avoid language that creates an expectation the evidence cannot justify.
What a dental practice website should display
GDC advertising guidance says a dental practice website should display:
- The name and geographic address where the dental service is provided.
- Contact details, including an email address and telephone number.
- The GDC's address and contact details, or a link to the GDC website.
- Details of the practice complaints procedure and the appropriate escalation route.
- The date the website was last updated.
Where a dental professional is named as providing care, the website should show the person's professional qualification, the country where it was awarded and the GDC registration number. The information should be kept current as personnel and services change.
The website should also state clearly whether the practice is NHS, mixed or wholly private. Prices and availability should not be presented in a way that obscures material conditions.
Treatment claims need appropriate evidence
The ASA expects marketers to hold robust evidence for objective dental treatment or product claims. The evidence should relate to the specific intervention and the wording used. A study about one product does not automatically support a broader claim about a different system or every patient.
Review phrases such as:
- "pain-free", "risk-free" or "guaranteed results";
- "the best", "leading" or "number one" without verifiable comparative evidence;
- fixed outcome claims that ignore assessment, suitability or individual variation;
- speed claims that hide important conditions or make an atypical result appear standard;
- clinical claims copied from a manufacturer without checking whether the evidence supports the practice's wording.
GDC guidance also says advertising on social and marketing websites should make clear that treatment may not be appropriate for every patient and is conditional on a satisfactory assessment. The practice still needs to assess the patient, take a medical history, obtain consent and explain options before treatment.
Present qualifications and specialist titles honestly
Patients may rely heavily on titles and credentials. Use the exact qualification and GDC registration details, and explain unfamiliar letters where useful rather than relying on a string of abbreviations.
GDC guidance reserves specialist titles for dentists on the relevant specialist list. A dentist who is not on a specialist list should not use wording that implies specialist status. The guidance distinguishes restricted specialist claims from wording such as a special interest, experience in a treatment or a practice limited to an area, provided the description remains accurate and not misleading.
Comparisons between the skills or qualifications of professionals also need care. Do not imply that another registrant is less capable without an appropriate and permissible basis.
Before-and-after images must be genuine and representative
ASA dental guidance says before-and-after photographs should be genuine and representative, with signed and dated proof held by the marketer. Consent and confidentiality must also be managed properly.
Review the entire presentation, not only whether the photographs are real. Lighting, angle, cropping, makeup, image processing, tooth dehydration and selective case choice can all change the impression. The caption should not imply that every patient will achieve the same result.
Keep a record linking the consent, source images, dates, treatment and approval. If an agency or clinician posts the material on social media, the same evidence and consent discipline should follow the asset.
Social media, paid ads and influencer content
A post does not escape advertising rules because it feels informal. Promotional content published by the practice, a clinician, an employee, an agency or a paid creator may still be advertising. Paid or incentivised relationships should be disclosed clearly where required.
- Keep patient information confidential, including details that could identify someone indirectly.
- Use a review process for treatment claims, images, price promotions and credentials.
- Make material conditions easy to see, not buried in a later slide or small caption.
- Do not use fear, shame or unrealistic transformation language to pressure a decision.
- Keep account access and approval responsibilities clear when an external agency posts.
GDC social media guidance also reminds dental professionals that online conduct can affect public confidence and that content can be copied and redistributed even after deletion.
Cosmetic dental promotions need extra care
Cosmetic advertising can create particular risks around body image, vulnerability, before-and-after presentation and treatment expectations. ASA guidance for cosmetic interventions prohibits targeting relevant ads at under-18s and warns against exaggerated or unrealistic claims.
Prescription-only medicines cannot be advertised to the public. If a campaign crosses into prescription treatment or broader cosmetic intervention marketing, obtain appropriate advice before publication.
Price promotions should state what is included, who is eligible, the assessment requirement, important time limits and any other material conditions. Avoid creating artificial urgency around a healthcare decision.
Compliant dental marketing is not weak marketing. Specific, supportable information gives patients a better reason to trust the practice than an exaggerated claim.
A practical dental marketing approval workflow
- Draft the claim precisely. Identify whether it is factual, clinical, comparative, promotional or a patient-experience statement.
- Identify the evidence. Keep the source that supports the exact wording, not a loosely related article.
- Check credentials and registration details. Confirm titles, qualifications, countries of award and GDC numbers.
- Review material conditions. Include assessment, suitability, price, timing or availability limits where they affect the offer.
- Check imagery and consent. Confirm authenticity, representativeness, confidentiality and the scope of consent.
- Approve the final format. Review the page, ad or post as the patient will see it, including captions and linked landing pages.
- Record and revisit. Keep the approval evidence and review time-sensitive claims when services, prices or guidance change.

Frequently asked questions
Dental advertising must be legal, decent, honest, truthful, accurate and not misleading. Claims should be supported by suitable evidence, credentials must be presented honestly, and marketing should not create unjustified expectations about treatment results.
GDC guidance says practice websites should display the practice name and geographic address, contact details, GDC contact details or a link, complaints information and the date the website was last updated. Dental professionals named as providing care should show their qualifications, country of qualification and GDC number.
Yes, but ASA guidance says dental before-and-after images must be genuine and representative, and the marketer should hold signed and dated proof. Images and surrounding claims must not exaggerate the results a patient is likely to achieve.
