Before-and-after images are among the most persuasive content a dental practice can publish, but without the right consent process they become a serious compliance liability. This guide explains exactly what UK practices need to do to use patient photography safely and legally.
Before-and-after photographs are some of the most compelling content a dental practice can put in front of prospective patients. They show real results, build trust quickly, and demonstrate clinical skill in a way that no amount of copywriting can match. The problem is that a significant number of practices are using these images without a robust consent process in place, leaving themselves exposed to complaints, regulatory action, and reputational damage. If you have ever published a patient photograph on your website, your social media, or in any marketing material without a carefully documented, specific, and informed consent procedure, this article is worth reading carefully.
In the UK, the use of patient images in dental marketing sits at the intersection of several regulatory frameworks. The General Dental Council sets the professional standards. The Advertising Standards Authority governs how those images are used in promotional contexts. The UK GDPR and the Data Protection Act 2018 govern how patient data, including photographs, is stored and processed. And the Consumer Protection from Unfair Trading Regulations 2008 applies whenever images are used to influence purchasing decisions.
A patient photograph is special category data under UK GDPR. It can reveal health information, and that means the threshold for lawful processing is higher than it is for ordinary personal data. Consent, in this context, must be freely given, specific, informed, and unambiguous. A vague statement buried in a new-patient registration form will not meet that standard. Neither will a verbal agreement that was never documented.
The GDC's Standards for the Dental Team, particularly Standard 4 on patient confidentiality, makes clear that patient information, including images, must not be disclosed without valid consent. Breaching that principle is not simply an administrative error. It can be treated as professional misconduct.
Many practices obtain consent for clinical photography as part of their records process, but that is not the same as consent to use those images in advertising. A patient who agreed to photographs being taken for their clinical file has not necessarily agreed to those photographs appearing on your Instagram feed or your homepage. The two purposes must be consented to separately, in plain language, and the patient must understand each one before they agree.
Valid consent for marketing use needs to tell the patient exactly what you plan to do with their image. Will it appear on your website? In paid social media advertising? In print materials? On Google Business Profile? Each channel represents a different context, and patients have a right to understand and approve each one. A form that simply says "for promotional purposes" is too vague to be relied upon if a complaint is raised.
Even if consent was obtained verbally and genuinely, it is worthless if it cannot be demonstrated. Your consent records should be written, signed by the patient, dated, and retained for as long as the image remains in use. If a patient withdraws their consent two years after the photograph was taken, you need to know immediately which images are affected and be able to act quickly.
Patients have the right to withdraw consent at any time, and when they do, you must stop using their image promptly. This sounds straightforward, but it creates a practical challenge if your images are spread across multiple platforms, embedded in website pages, or running in live advertising campaigns. Without a clear internal process for tracking which images are in use and where, removing them all quickly is harder than it sounds.
The ASA requires that before-and-after images used in dental advertising represent genuine, typical results. Heavily edited photographs, images where the lighting or angle creates a misleading impression, or cases presented as typical when they represent exceptional outcomes are all potential grounds for an upheld complaint. The GDC also expects that marketing does not create unrealistic expectations.
Getting this right is not complicated, but it does require a deliberate process rather than an ad hoc one. Here is what a robust system should include.
This should be a separate document from your clinical photography consent, written in plain English, and covering the following points clearly:
The form should support a conversation, not replace it. Your clinical or front-of-house team should walk the patient through what they are agreeing to, answer any questions, and give the patient time to consider rather than presenting the form as a formality to be signed quickly. Consent obtained under pressure, or without genuine understanding, is not valid consent.
Maintain a simple log that records: the patient reference, the date of consent, the treatment shown, which platforms the image has been published to, and the date of any withdrawal. This does not need to be sophisticated. A spreadsheet managed by your practice manager is sufficient, provided it is kept up to date consistently.
Decide in advance how quickly you will act when consent is withdrawn, and make sure whoever manages your platforms knows the process. Removing an image from your website and social profiles within 48 hours of a withdrawal request is a reasonable standard. If images are running in paid advertising, those campaigns need to be paused and the creative swapped out as a priority.
At least twice a year, review all before-and-after images currently in use across your website, social media, and any other channels. Check that each one has a corresponding consent record on file and that the consent covers the current use. This is particularly important if your website has been updated or rebuilt, since images can sometimes be carried over from older versions without anyone checking the associated records. If your practice website needs reviewing with compliance in mind, it is worth looking at how your digital presence is structured overall, and a good starting point is considering whether your website design makes it easy to manage and update content responsibly.
When a practice works with a dental marketing agency that understands the regulatory environment, the approach to before-and-after photography changes considerably. Rather than treating consent as an afterthought, it becomes part of the production process from the start.
A specialist agency will typically provide guidance on consent form wording before any photography takes place, advise on how images should be framed and edited to avoid misleading impressions, and flag ASA and GDC risks when reviewing copy or creative that accompanies the images. They will also understand the practical implications of running before-and-after content in paid advertising, where the ASA's rules on substantiation are particularly relevant.
Equally important is the ongoing relationship. A general marketing agency or freelancer may not know that a patient has a right to withdraw consent, or what that means for a live paid social campaign. A dental-specialist agency builds that into how it manages accounts, so that if a withdrawal occurs, the process for acting on it is already understood by everyone involved.
This kind of joined-up approach also means that your marketing material is less likely to attract complaints in the first place. Images that are authentic, clearly representative of genuine outcomes, and accompanied by appropriately worded copy are far less vulnerable to ASA challenge than content produced without that regulatory awareness.
It is worth saying plainly: patients who feel their images were used without proper consent, or in ways they did not expect, do not simply raise regulatory complaints. They leave negative reviews, they tell other patients, and they do not return. The reputational cost of mishandling consent is often greater than the regulatory consequence, particularly in communities where word of mouth still carries real weight. Getting this right is as much about trust as it is about compliance.
If you are not entirely confident that your current consent process would withstand scrutiny from the GDC or ASA, now is a good time to address it, before an image is questioned rather than after. The changes required are usually straightforward, and having them in place means you can use before-and-after photography with confidence, knowing it is working for your practice rather than creating risk.
