Facebook ads guide for dental practices: how to run Meta ads under UK health rules

Where Meta fits: a Facebook ads guide for dental practices starts with the job

Meta means Facebook and Instagram, which run from one ad system, Meta Ads Manager. The first decision is what you want Meta to do, because it does a different job from Google.

Google search shows your ad to someone who just typed the treatment into a search box. Meta shows your ad to people who weren't looking, chosen by its delivery system. That makes Meta good at two things for a practice: creating interest in a treatment the patient hadn't considered yet, and staying in front of someone during a long decision.

Full-arch gets its own treatment on marketing full-arch treatment, and bonding on composite bonding marketing.

My rule: if a practice hasn't yet got search working for its high-value treatments, that comes first. Meta is added when there's a treatment it suits and a way to count which of its leads turn up.

Campaign structure

A Meta campaign has three levels. The campaign holds the objective, which is what you want Meta to get you. The ad set holds the audience, placements, budget and performance goal. The ad holds the creative and, for lead ads, the form.

For a practice, the objective is almost always Leads. I build one campaign per treatment, because each treatment has its own offer, its own form and its own value.

Advantage+ leads campaigns. Meta's automated option for leads switches on Advantage+ for budget, audience and placements by default. It still supports instant forms, website forms, calls and click-to-message, and the same performance goals as a manual campaign. If you manually choose placements or set ad set budgets, Advantage+ turns off.¹

Advantage+ campaign budget. With this on, you set one budget at campaign level and Meta moves it between ad sets towards the best opportunities. Meta says it's best suited to campaigns with at least two ad sets, may not spend evenly across them, and should be judged at campaign level.²

Performance goals. The performance goal tells Meta what to find. For lead ads the options include maximising the number of leads, maximising the number of qualified leads, and maximising the value of conversions.³

One date matters. Meta says that from April 2026 the qualified-leads goal is no longer available for new campaigns without a Conversions API integration, with existing campaigns affected from August 2026.³ So if you want Meta to optimise for quality rather than volume, the measurement build is no longer optional.

Why so few ad sets. It's tempting to split a campaign into many ad sets, one per interest, age band or town. For a single practice that usually spreads the budget so thin that no ad set gathers enough results for Meta to learn from, and you can't tell a real difference from noise. I start with one ad set per treatment and put the variety into the creative instead, where Meta can test it inside the same budget. A second ad set earns its place only when it tests something that matters, such as an instant form against a landing page.

Budget. Set it the same way as for search: work back from the consultations you want, through your own booking and attendance rates, to the leads and spend needed. Then check it against clinical capacity. A budget copied from another practice tells you nothing about yours.

What happens when the goal is set to raw lead volume is covered in why Meta leads don't turn up.

Audiences under health rules

Audience targeting on Meta has changed a lot, and health rules narrow it further. Here's what's available and how I use it.

Advantage+ audience. Meta's AI finds the audience using information such as past conversions, Meta Pixel data and interactions with previous ads. Meta recommends A/B testing it for almost all campaign types except retargeting.⁴ In practice this means Meta's system, not your settings, does most of the finding. Which makes the signal you feed it, covered under Measurement, the real targeting.

Detailed targeting. Detailed targeting lets you choose audiences by demographics, interests and behaviours. When you describe an audience to Meta's AI, Meta tells you to avoid sensitive topics such as health information.⁵ Detailed targeting exclusions were removed from new ad sets in Ads Manager from 31 March 2025, though custom audience exclusions remain.⁶

Custom audiences from patient lists. Meta's terms prohibit sharing health information through its business tools, and say the names and criteria for custom audiences must not reflect, imply or be based on prohibited information.⁷ A list of your implant patients is health information about those people. I don't upload patient lists built on treatment, and I don't name audiences after treatments.

Age. Meta's health and wellness standard requires ads promoting health products and services to be targeted at people aged 18 or over.⁸ High-value dental treatment is an adult decision anyway, so I target adults.

Location. A radius around the practice, set by how far patients will realistically travel for the treatment. Full-arch patients may travel further than bonding patients.

Meta may also assign your website to a health and wellness category, which can restrict what your site shares with Meta.⁹ If that happens, some audiences built from website activity won't be available. Check the category in Events Manager rather than assuming.

Creative

On Meta, the creative does most of the targeting work. The ad's content decides who stops, who watches and who fills in the form. For dentistry it also carries most of the compliance risk.

Three rules sit on every dental ad:

1. Don't assert or imply a personal attribute. Meta's policy says ads must not assert or imply personal attributes, including physical or mental health, and must not use "you" language about a personal attribute.¹⁰ "Missing teeth?" and "Do you hate your smile?" both fail.
2. Don't attack appearance. Meta's health and wellness standard bans statements of inferiority about appearance, including negative questions about someone's body parts.⁸
3. Don't promise results. The GDC says advertising must not create unjustified expectations about results,¹¹ and the ASA says before-and-after photos must be genuine and representative, with signed and dated proof.¹²

Meta's own standard permits before-and-after images for general cosmetic procedures,⁸ but UK rules add their own conditions. They're set out in before-and-after photos.

I rotate several creatives per ad set, so Meta can find what works, and replace them when results drop. People in a practice's radius see the same ads repeatedly, so an ad that booked consultations for weeks can wear out. I judge that on booked consultations per creative, not on clicks, and I keep a simple log of each creative's angle, hook and sign-off date so the next round builds on what worked rather than starting over. Real footage of your own clinicians and practice beats stock images for high-value work. Nobody books an implant consultation because of a stock photo.

Forms versus landing pages

Meta lead ads can collect details on an instant form, which opens inside Facebook or Instagram, or send people to a landing page on your website.

Instant forms come in types. More volume is the default and is quick to submit on a phone. Higher intent adds a review screen and inline context saying the business may follow up, and only runs in Facebook and Instagram feeds on mobile. Rich creative lets you add images, colours and extra text.¹³ You can add up to 15 custom questions, use conditional logic, add an appointment request question, and require SMS verification of the phone number.¹⁴

A qualifying question is one that helps the practice judge fit before calling. Good ones are easy to answer and tell reception something useful. None of them should ask about the patient's health in a way that turns the form into a medical questionnaire.

Which to use depends on the treatment, the qualifying questions and how quickly the practice calls. My working rule, and the decision in full, is on lead forms versus landing pages.

Measurement

The measurement question for Meta is the same as for any channel: which ads produced consultations that turned up, and then treatment? Meta can't answer that on its own. It only sees the lead.

Getting leads out of Meta. Meta lets you download leads, or connect a CRM directly, through a third-party tool, or by a custom integration.¹⁵ A CRM here just means wherever the practice tracks leads. Leads sitting unread in Ads Manager go cold.

Sending stages back. The Conversions API sends events from your systems to Meta server to server. When the same event is sent from both the browser Pixel and the Conversions API, Meta needs a matching event name and event ID to count it once.¹⁶ For lead stages, I send two events only: "consultation booked" and "consultation attended", under generic names, with hashed identifiers, and only for patients whose explicit consent is recorded. Those let Meta optimise towards booked and attended consultations without naming a treatment, and Meta may restrict or reject them for a health advertiser.

The health-data limits. Meta's prohibited information list includes medical procedures, treatments and testing, and applies to event names, custom data, URL parameters and custom audiences.⁷ Meta may also place a site in a health and wellness category and apply restrictions: core setup, which strips custom parameters and URL paths; restrictions on specific mid and lower funnel standard events; or full restrictions.¹⁷ Meta's advice for restricted accounts is to look at upper-funnel events instead. Design the event names and data so they reveal nothing about treatment, and check Events Manager for restrictions before building a strategy around an event. If the two stage events are restricted, they may not be usable at all, and the account runs on upper-funnel events instead.

Consent. Meta says that where consent is required, no data should reach it until the person has given consent, and the Pixel shouldn't share data until cookies are accepted.¹⁸ Your cookie banner is part of your Meta measurement.

What to report. Each week, per treatment: spend, leads, leads contacted, consultations booked, consultations attended, and the cost of each. Each month, add treatment starts. Report leads by the week they arrived, not by the week they booked, so you can follow each group through. A full-arch patient who books three months after the lead still counts for the ad that found them, and judging the campaign too early would call it a failure it isn't.

The detail is on the Conversions API and its health-data limits. Why cost per lead misleads, and what to report instead, is on why cost per lead misleads. If a term here is new, the dental marketing glossary has the definition.

Policy

Meta ads for a UK practice sit under two rulebooks: Meta's advertising standards and data terms, and UK dental advertising rules. Both apply to every ad, form and landing page.

The platform side in more depth is on Meta's health ad policy for dentists. Ads that break Meta's rules get rejected; ads that break UK rules can reach the ASA or the GDC. I scan every ad against both before it runs and get the principal's sign-off on every claim.

If you'd like your Meta ads held to this method, email [email protected] with the treatment you want more of and what you can currently see about which leads turn up. A first look is free: I review the Meta ads I can see publicly and the pages behind them, from the outside, and reply with what I find.
