GDC advertising guidance, explained for practice owners

What the guidance is and how old it is

The General Dental Council (GDC) is the UK regulator for dentists and dental care professionals such as hygienists, therapists, nurses, technicians and orthodontic therapists. Registration with the GDC is what allows someone to practise.

The GDC sets out what it expects of registrants in the Standards for the Dental Team, often called the "silver book". Standard 1.3.3 is the advertising rule: "You must make sure that any advertising, promotional material or other information that you produce is accurate and not misleading."² The guidance on advertising is the more detailed document that explains how to meet it. The GDC's own page quotes standard 1.3.3 with an added clause saying advertising must also comply with "the GDC's guidance on ethical advertising".¹

The guidance page still shows "Effective from 30 September 2013".¹ That date matters for two reasons:

1. It predates most of today's marketing channels in their current form. Paid social, Google Business Profile posts and short-form video were not what they are now.
2. The text has been touched since, without a new date. The guidance's examples of marketing sites now include "Instagram, TikTok, LinkedIn, Groupon, X". Neither TikTok nor a platform called X existed when the guidance took effect. So the wording has been refreshed, but the page shows no revision history.

In Scotland, the SDCEP Practice Support Manual points practices to the same GDC standards and guidance for advertising.⁵ The guidance is UK-wide.

What it requires

The guidance sets requirements for all advertising, then adds rules for particular cases: services that need extra training, promotions on marketing and social sites, product endorsements, and websites.

For all advertising that carries your name, you must:¹

If you offer services your primary qualification doesn't cover, the guidance says you must get the extra training first, and "you should make clear that you have undertaken extra training to achieve competence".¹ This bites hardest for facial aesthetics offered in dental practices.

If you promote on marketing or social networking sites, you "must make clear that the treatment advertised may not be appropriate for every patient and that it is conditional on a satisfactory assessment being carried out".¹ In practice, a sentence such as "Suitability is confirmed at an assessment" belongs on every promotional post, boosted post and paid social ad. The GDC's wider rules for social platforms are covered on the page about the GDC's social media guidance.

If you endorse products, you should only give "factual information about the product which can be verified by evidence", and avoid implying the whole profession shares your view.¹

If you run a practice website, it must display the practice's name and address, contact details, the GDC's contact details or a link to the GDC website, the complaints procedure, and the date the site was last updated. Each dental professional named must show their qualification, the country it comes from and their GDC number.¹ The full checklist, with the items other rules add, is on the page covering website requirements.

What it prohibits

The guidance's prohibitions are short, and most breaches come from a handful of them.¹

• Unjustified expectations. You must avoid "statements or claims intended or likely to create an unjustified expectation about the results you can achieve." Headlines promising a result ("your perfect smile") are the usual problem.
• Comparing professionals. You must not display information "comparing the skills or qualifications" of any dental professional with those of others. "Our most experienced implant surgeon in the region" is a comparison.
• Implied specialist status. Only dentists on a GDC specialist list may use "Specialist" or titles such as Orthodontist or Periodontist. Dental care professionals must not use titles like "Smile specialist" or "Denture specialist". The rules, and the alternatives such as "special interest in", are on the page about specialist titles and 'special interest' wording.
• Abbreviated honorary degrees and memberships. You must not list memberships, fellowships or honorary degrees "in an abbreviated form because it may mislead patients". Write them out in full or leave them off.
• Exploiting patients. You "must not exploit the trust, vulnerability or relative lack of knowledge" of patients. Urgency tactics on treatment ("only three slots left") sit badly with this.

Passing the GDC check doesn't mean an ad is compliant overall. The ASA applies its own tests to the same ad, and they are stricter on evidence.

How it is enforced

The GDC doesn't pre-approve adverts. It acts after the event, against the individual registrant.

The guidance states that advertising which is "false, misleading, or has the potential to mislead, is unprofessional, may lead to a fitness to practise investigation and can be a criminal offence".¹ Fitness to practise is the GDC's process for deciding whether a registrant is safe and suitable to keep practising without restriction. An advertising concern can start that process like any other concern.

Three points follow from how the guidance is written:

1. The named person carries it. "Whenever you, your practice, or any place where you work as a registrant, produce any information containing your name, you are responsible for checking that it is correct."¹ An associate named on a practice website is responsible for their own entry.
2. Patients can check. The guidance notes that patients can check registration and specialist status on the GDC register, but are more likely to rely on what you tell them.¹ That is why the GDC treats honesty about qualifications strictly.
3. The GDC is one of several enforcers. The same misleading claim can also be referred to the ASA, which enforces the CAP Code on your website and social accounts regardless of any GDC action.

Compliance with the guidance has been measured once, as far as I can find. A study in the British Dental Journal checked 450 practices in North East England and North Cumbria. It reported "only seven websites (1.8%) were fully compliant with GDC advertising guidance".⁶

That was one region in 2021. It says nothing reliable about your practice, but it does show that full compliance is rare, and the authors put it down mainly to registrants not knowing the scope of the guidance.⁶

What may change

The guidance is under review, but the review has not produced new advertising rules yet.

On 2 June 2026 the GDC opened a consultation on replacing the Standards for the Dental Team with a Framework for Professionalism: four principles supported by expectations, statutory professional guidance and practical resources.⁴ The GDC's stated reason is that the current standards are "overly prescriptive". The consultation closed on 31 August 2026.⁷

The GDC's consultation draft of its future professional guidance lists the guidance on advertising as "to stay live with a light touch update to reflect the Principles, until it can be reviewed and replaced with Professional Guidance on communication".⁸ That draft is marked for consultation purposes only, so treat it as a signal of intent, not a decision.

What this means for your marketing now:

• The 2013 guidance still applies in full. Nothing in the consultation suspends it.
• The core duties are unlikely to disappear. Accurate claims, GDC numbers and specialist titles rest on standard 1.3.3 and the specialist list regulations, not on the guidance's format. That is my reading, not a GDC statement.
• A replacement will need a content review. When the GDC publishes guidance on communication, every treatment page, ad template and social caption should be checked against it. I update this page when that happens.

The guidance turns into specific checks on what a UK dental website must show and on specialist titles. For a free first read of your pages and ads against it, email Fayez@imfayez.com.
