A lot of UK dental marketing quietly breaks rules the practice is already bound by. Missing GDC numbers, implied specialist status, adverts for Botox, and prices that hide the real cost. Most of it is fixable in an afternoon, and fixing it makes you the practice patients trust
The uncomfortable argument
Dentistry is one of the most heavily regulated things a small business in the UK can do, and that regulation does not stop at the surgery door. It follows your marketing. The General Dental Council sets rules for how you advertise. The Advertising Standards Authority sets rules for what you can claim. The rules on prescription medicines sit on top of both. And a large share of practice websites, social posts and price boards quietly break at least one of them.
This is rarely dishonesty. It is usually a marketing agency or a well-meaning team member who did not know the rules, copied what a competitor was doing, and assumed it was fine. The problem is that “everyone does it” is not a defence. The GDC can act on your registration. The ASA publishes its rulings for anyone to read. And advertising a prescription-only medicine to the public is against the law, not just the guidance.
This report is not here to frighten you. It is here to show you the common breaches, explain the rule behind each one in plain English, and make the simple case that getting this right is not just about avoiding trouble. In a market where patients are nervous about cost and trust, the practice that markets honestly and clearly stands out for exactly the right reasons.
Key takeaways
- Your marketing is regulated by the GDC and the ASA, not just by good taste. “Legal, decent, honest and truthful” is the standard, and a lot of practice marketing falls short of it.
- Advertising Botox by name to the public is not allowed. Botulinum toxin is a prescription-only medicine, and there are clear rules against promoting prescription-only medicines to the public.
- The word “specialist” is protected. Only dentists on a GDC specialist list may use it or titles like orthodontist or periodontist. Others should use phrases like “with a special interest in”.
- Claims need evidence. Teeth-whitening and cosmetic results must be substantiated, and before-and-after photos must be genuine, representative and backed by dated proof you keep on file.
- Prices must not mislead. A “from” price should include all non-optional charges, and if the final cost depends on a consultation you should say so up front.
- Compliance is a marketing advantage, not just a risk to manage. Clear prices, honest claims and proper credentials are exactly what nervous patients are looking for.

The rules your marketing already lives under
Most practice owners know their clinical obligations inside out. Far fewer have read the advertising rules, even though they apply to every page of the website and every social post. Here are the ones that catch practices most often.
| The rule | What it means for your marketing |
|---|---|
| GDC registration number | The GDC expects the registration numbers of the dental professionals you name to appear in your advertising. Many practice “meet the team” pages list dentists with no GDC number at all. |
| The word “specialist” | Only dentists on a GDC specialist list may call themselves a specialist or use titles like orthodontist, periodontist or endodontist. If you are not on the list, use “experienced in” or “with a special interest in”. |
| NHS, private or mixed | You must make clear whether the practice is NHS, fully private or mixed. Vague wording that leaves patients guessing is a common and easily fixed breach. |
| Complaints information | Your site should set out your complaints procedure and who patients can turn to if unhappy, such as the Dental Complaints Service for private care. |
| Honest and substantiated claims | Everything must be accurate and not misleading. Superlatives like “best”, “painless” or “perfect” and unproven results are the claims the ASA acts on most. |
This is a plain-English summary, not the full guidance. Always check the current GDC and ASA rules before publishing, and take professional advice if you are unsure.
The breaches most practices commit
None of these are exotic. Walk through ten UK practice websites and you will see most of them. The point is not that the practices are bad, it is that the marketing was never checked against the rules.
- Advertising “Botox” by name. Promoting a prescription-only medicine to the public is not allowed. Wording like “Botox from sixty-five pounds” on a public page is one of the most common breaches in the sector.
- Implying specialist status. Calling a dentist an “orthodontist” or “implant specialist” when they are not on the relevant GDC list, rather than “experienced in” that area.
- Unproven cosmetic claims. “Whiter teeth instantly”, “completely painless”, “perfect smile guaranteed”. Results claims need real evidence, and absolutes are very hard to support.
- Before-and-after photos with no proof. Using treatment photos that are not clearly genuine and representative, or that you cannot back up with dated records.
- Missing GDC numbers and status. Team pages and adverts that name clinicians without registration numbers, or that never say whether the practice is NHS or private.
- Misleading “from” prices. A headline price that leaves out consultation, X-ray or follow-up fees, so the figure a patient sees is never the figure they pay.
The Botox problem most clinics get wrong
This one deserves its own section because so many practices get it wrong and the rule is firm. Botox is a brand name for botulinum toxin, which is a prescription-only medicine. There are clear rules against advertising prescription-only medicines to the public. That means a public web page, leaflet or social post that promotes “Botox”, by name and especially with a price, is very likely breaking those rules, not just GDC guidance.
The fix is not to stop offering the treatment. It is to change how you talk about it in public. Practices that get this right describe the outcome rather than naming the medicine, using wording such as “anti-wrinkle treatments” or “facial aesthetics consultations”, and they discuss specific medicines only in a private clinical setting after a consultation. The treatment is the same. The advertising is compliant.
The “from forty-nine pounds” problem
Price is where good intentions and the rules collide most often. A “from” price is allowed, but it has to be honest. The ASA’s position is that an advertised price should include all non-optional charges, and that if the final cost genuinely depends on a consultation, you should say so clearly rather than letting a low headline figure do the selling.
In dentistry the gap between the headline and the bill is often large. A “new patient exam from twenty-nine pounds” that does not mention X-rays, or “implants from fifty pounds a month” with no mention of term, deposit or total, is the kind of claim that frustrates patients and attracts complaints. The irony is that clear, complete pricing is also what nervous patients want most. Honesty here is both the rule and the better sales tactic.
Why compliant marketing wins more patients
It is tempting to read all this as a list of things you can no longer do. That is the wrong way round. Patients choosing a dentist are often anxious, both about the treatment and the cost. They are scanning for reasons to trust you. Clear prices, honest claims, visible credentials and plain language about NHS or private care are exactly the signals that build that trust.
So the practice that markets within the rules does not look restricted. It looks like the grown-up in the room. While competitors run vague “from” prices and name prescription medicines they should not, the compliant practice quietly looks more professional, more transparent and safer to choose. The rules, followed properly, are a positioning strategy you are being handed for free.
What to fix this week
You do not need a lawyer or a new website to make most of these right. This is an afternoon of careful checking and editing. Work through it page by page.
- Take prescription medicine names off public pages. Replace “Botox” and similar with outcome-based wording like “anti-wrinkle treatments”, and keep specific medicine and price discussions to private consultations.
- Add GDC numbers and practice status. Put registration numbers on every clinician you name, and state clearly whether you are NHS, private or mixed.
- Fix the word “specialist”. Only use it, or titles like orthodontist, where the dentist is on the relevant GDC list. Otherwise switch to “with a special interest in”.
- Make every price complete. Ensure each “from” price includes all non-optional costs, or clearly says the final figure depends on a consultation.
- Check your claims and photos. Remove absolutes like “painless” or “guaranteed”, and make sure every before-and-after image is genuine and backed by dated records you hold.
- Turn trust into your marketing. Compliance frees you to compete on reputation. Build a steady flow of genuine reviews and reply calmly to the hard ones. See our guides to getting more Google reviews and responding to a bad review, and our guide to what marketing should cost to spend on it sensibly.
This is Start and Build work in the clearest sense. Get the foundations honest and compliant first, then market hard on top of them. A practice that does this is not just avoiding a GDC or ASA problem. It is becoming the obvious, trustworthy choice in its town.
Methodology and sources
Compiled by Whito in June 2026. The advertising obligations described, including the expectation that GDC registration numbers appear in advertising, restrictions on the use of “specialist” and titles such as orthodontist, the requirement to state whether a practice is NHS, private or mixed, the need for a complaints procedure and reference to the Dental Complaints Service for private care, and the standard that all material be legal, decent, honest and truthful, are drawn from the General Dental Council’s guidance on advertising and its Standards for the Dental Team. The rules on misleading claims, substantiation of teeth-whitening and cosmetic results, genuine and representative before-and-after photos supported by dated proof, and complete and honest pricing including “from” prices, reflect the Advertising Standards Authority and Committee of Advertising Practice advice and published ASA rulings, including teeth-whitening and cosmetic rulings in 2024. The point that Botox, a brand of botulinum toxin, is a prescription-only medicine that may not be advertised to the public reflects the rules on advertising prescription-only medicines under UK medicines law and ASA and CAP guidance. This report is a general, plain-English summary intended to help practices review their own marketing. It describes common issues across the sector and is not a comment on any named practice or individual. It is not legal, regulatory or professional advice. Rules change and details vary, so always check the current GDC, ASA, CAP and medicines guidance, and take professional advice, before acting.
