Digital marketing for dental clinics in 2026: what works and what can get you fined

1. How patients choose a dentist

Let's start with what has been measured in Spain. A study by Universidad Europea de Madrid published in BMC Oral Health in 2023 asked 503 dental service users what they value when choosing a clinic. First came facilities and technology, then recommendation from family and friends. Least valued were social media presence and website quality.

That does not mean the website does not matter. 41.4% had visited a clinic's social media or website. And among those who consulted them the last time they changed clinic, 86% said it influenced their decision. The reasonable reading is that patients do not value the website itself but what it lets them check: whether the clinic is as described.

Other studies add nuance. In New Zealand, with 249 people, proximity and referral from another professional guided the choice, and the most valued trait in a dentist was explaining treatment options. They are patients in another country, but it matches what a website must do: say where you are, who will treat you and how you work.

The market in figures

Competition varies a lot by location. Using professional and population data, Madrid has about 136 dentists per 100,000 inhabitants, against about 89 nationally and about 46 in Castilla-La Mancha. It is our own calculation, and it serves one purpose: the same strategy does not cost the same in central Madrid as in a provincial capital.

2. Each treatment needs different marketing

The most common mistake is running a single campaign for «the clinic». A patient in pain on a Sunday and another who has been thinking about implants for months search very differently. This classification is ours, not a statistic, but it helps decide where to put the money:

These figures show why an implant can bear an acquisition cost that a cleaning cannot. And why, for a check-up, what counts is the patient returning and bringing others, not the ad.

3. SEO for dental clinics

Here Google is clearer than in other sectors. Its rater guidelines treat health as a «your money or your life» topic and say medical pages require a high level of trust. They even give, as an example of the lowest quality, a page about dry socket with no author or contact, because it can affect how people seek treatment. Rater assessments do not directly affect rankings, and Google clarifies that E-E-A-T is not a specific factor, but it gives a good idea of what it looks for.

1. 01One page per treatment. What it is, who it is for, how many visits it takes, what risks it has and how it is quoted.
2. 02Real signatures. Each page with the dentist who reviews it, their registration number and qualification.
3. 03A profile per dentist. With education and areas of work. Exaggerated credentials work against you.
4. 04Real photos of the clinic. If facilities and technology are what is valued first, show them.
5. 05Indicative prices when you can. If price is the big barrier, a reference with its conditions helps people searching.
6. 06Verifiable citations. When you state something clinical, link to a serious source.

Technical details that matter

• The schema.org «Dentist» type is the correct local business subtype, although it gives no special feature in results.
• FAQ rich results disappeared from Google on 7 May 2026, also in health. Keep questions for the reader, not for the result.
• Stars from your own reviews are not shown: if you control the reviews about your clinic, you cannot get them.

To see what it costs, we explain it in how much SEO costs. Monthly SEO starts from €390/month (plus VAT where applicable) and local SEO from €290/month (plus VAT where applicable).

4. Business Profile and reviews

Google explicitly names dentists among individual practitioners. That has consequences: the clinic has its profile, each client-facing dentist can have their own with only their name, and if there is a single dentist under a brand, a shared profile in the format «Brand: Name» is recommended. Support staff have no profile, and no profile is created for each speciality.

What Google allows with reviews

• You can ask your patients for them with a Google link or QR code.
• You cannot give anything in return, neither discounts, nor a free cleaning, nor a prize draw.
• You cannot ask only happy patients or discourage negative reviews.
• Medical or identifying data is not allowed in published content.

Third-party reviews weigh more than your own. In a University of Sheffield study of 401 British clinic websites, all 1,798 testimonials on their own sites were positive, and Google and Facebook reviews were seen as more reliable. It is better to link to your Google listing than to select testimonials.

Reply, but without data

An experiment with 410 people published in Health Communication found that replying to reviews improves trust and intention to visit, even when they are negative, and more so if the dentist replies. But it has to be done well.

5. Google Ads for dental clinics

Google Ads' healthcare policy does not cover dental clinics: it deals with medicines, pharmacies or experimental treatments. That does not mean there are no limits, and the main one is less well known.

The personalised advertising policy treats health as a sensitive category, including invasive medical procedures such as surgery or injections. Ads in that category cannot use client lists, remarketing or similar audiences. Location, demographics and Google's interest audiences can be used.

How to measure without sending health data

• Google's customer data policy includes purchases of medical services among sensitive data, and bars uploading conversions tied to them for enhanced conversions.
• Measure with generic events such as «form sent» or «call», without the treatment in the event name or page address where you can.
• In Europe, consent is needed for cookies and for personalisation data. Google's Consent Mode does not include the banner, which is up to you.

And Spanish law still applies even if Google approves the ad. What applies to the site applies to the ad and its landing page. Account setup starts from €390 (plus VAT where applicable) and monthly management from €290/month (plus VAT where applicable), excluding ad spend.

6. Meta Ads: Instagram and Facebook

Social media works well for aesthetics, because it shows. A 2025 Saudi study of 552 people found that seeing previous cases influences the choice, especially on Instagram. But Meta has its own rules, and since September 2025 it has applied them more strictly.

• Do not imply the person has a problem. Meta does not allow stating or implying health attributes of the viewer. Going by Meta's example, «Missing teeth?» is risky, and «Dental implants in Seville» should not be.
• Before and after, over-18s only. Meta allows it for cosmetic procedures with that audience and without provoking negative self-perception. Its dental exemption is for products, such as whitening, not clinics. Its policy versions differ on other details, so review it before launching.
• Conversions and audiences without conditions. Since 2 September 2025, Meta blocks custom conversions suggesting specific health conditions, and its terms do not allow sending it health information.
• Forms without medical questions. Do not ask in a Meta form what treatment or condition the person has. Do it later, on your own channel and with the right legal basis.

To compare channels, we have a guide to Google Ads versus Meta Ads and another on the Meta Conversions API.

7. What can be advertised in Spain

As of November 2026 we have found no specific national law on health advertising. The Spanish Dental Council asked for one again in July and October 2026, after further clinic closures. What exists is a patchwork: the General Health Law, Royal Decrees 1907/1996 and 1277/2003, the General Advertising Law, consumer law and regional decrees.

«First visit free» and discounts

No national rule names «first visit free», but the risk exists. The Code of Ethics bars charging below cost as unfair competition (art. 51.5), and the Madrid Dental College's decalogue considers misleading messages such as «free implants», «from X euros» with no further detail or «in a single day», and asks discounts to state the previous price. That decalogue is a college document, not a law, but it gives a clear idea of what can be reported.

Testimonials

Article 4.7 of Royal Decree 1907/1996 bans patient testimonials as a lure, but its application to a clinic is debatable: Spain's Supreme Court said in 2020, in a dental chain case, that article 4 did not apply because the health purpose was beyond doubt, and upheld the ban on a leaflet with celebrities under the medical devices rule. The most defensible option remains linking to real Google reviews rather than publishing testimonials you select. Publishing consumer reviews without verifying them is also an unfair practice.

Before-and-after photos

Fines can be high. The General Health Law reaches €15,025.30 for serious infringements and €601,012.10 for very serious ones, and consumer law €1,000,000. These are general ceilings: we have found no specific official fine for dental advertising.

8. WhatsApp, reminders and messages to patients

Patients you already have are the cheapest channel, but here Spain's e-commerce law (LSSI) and the GDPR rule. Reminding of an appointment is not the same as selling a treatment:

The AEPD's guide for the health sector allows WhatsApp or SMS for appointments if one to one, with minimal data and offering alternatives. And do not use patients' social profiles to find them. If you want to automate reminders, this is exactly what to watch: that patient data does not go where it should not.

9. Trust is the best campaign

Context weighs. The closure of Dentix left 101,481 people affected according to Spain's Ministry of Consumer Affairs, and the Spanish Dental Council reported in October 2026 another final closure of a chain that left thousands of patients harmed. In cases like these, treatments paid in advance with credit often appear.

An independent clinic can turn that into an advantage. There is no need to speak badly of anyone, just have the site answer what patients want to know:

• Who will treat you, with name, registration and photo.
• How you pay: written quote before starting, as the Code of Ethics asks, and payment in stages if you offer it.
• What happens with financing. If there is linked credit, explain it. Law 16/2011 requires a representative example in advertising that mentions cost, and new EU consumer credit rules are still pending approval in Spain.
• Your clinical record is yours. Explain how it is handed over if the patient asks.
• Real photos and address. Nothing conveys more solidity than seeing where you will go.

10. What a clinic's marketing costs

Where to start on a small budget? Almost always with the Business Profile, reviews and a sound website, because that is what a recommended patient will check. Ads make sense when the page they lead to already convinces.

11. What about Colombia?

Dental advertising has been lawful since Ruling C-355 of 1994, which struck down the articles of Law 35 of 1989 restricting it. The Court accepts moderate advertising that weighs real qualities of the professional, and objects to advertising that only seeks to attract clients for financial gain or self-promotion, that denigrates colleagues or that manipulates.

• What remains in force. Do not offer a method as exclusive (art. 16), do not criticise colleagues (art. 28), publish only with a scientific basis (art. 53), and professional secrecy (art. 23).
• Titles. Unlike Spain, you can state «Orthodontics Specialist» if you hold that title from a recognised university.
• Ethics sanctions. They range from private reprimand to suspension of up to five years (art. 79), upheld by the Court in Ruling C-354 of 2022.
• Health data. It is sensitive data under Law 1581 of 2012: you need explicit authorisation and the patient may decline to answer.
• Google and Meta. Their restrictions on audiences and health data also apply to your campaigns.

We found no specific rule from the health regulators Supersalud or INVIMA on advertising dental services, nor published decisions of the Ethics Tribunal on websites. Before launching an aggressive campaign, seek advice. According to the health workforce register ReTHUS, in 2020 there were 48,616 dentists, one per 1,074 inhabitants, the latest public figure we have found.

There is a clear opportunity in patients from abroad. According to Bogotá's city government, Colombia received 26,786 foreigners for health reasons in 2025, up 18.4%. That is health in general, not only dentistry. But a site in English with indicative prices, travel logistics and a prior video consultation makes sense for anyone working with those patients.

With us, a bespoke website starts from COP 3,590,000 and monthly SEO from COP 1,410,000 a month, as indicative prices. We work remotely, and can travel if needed.

12. Where to start

1. 01Review the legal side. Registration number, authorised services, all-inclusive prices, no brands or celebrities.
2. 02Review the images. Remove anything identifiable without specific consent.
3. 03Tidy up the Business Profile. Clinic and dentists, with real details.
4. 04Ask everyone for reviews and reply without giving data.
5. 05Improve the website. One page per treatment, with a reference price, team and real photos.
6. 06Pick one treatment with good margin and demand in your area, and start there with SEO or ads.
7. 07Measure properly. Calls and forms, without health data, and which treatment each patient ends up hiring in your own software.
8. 08Look after your patients. Well-made reminders and a clear reason to come back and recommend you.
