Google Ads vs Facebook Ads for Dentists: Which Performs Better?

The definitive comparison — based on real campaign data from UK dental practices. Which channel wins for which treatment and which situation.

By Carl Fox, Denmarketing · Updated June 2026

Part of the complete dental marketing guide for UK practices. Google Ads and Facebook Ads are the two dominant paid channels for UK dental patient acquisition. They are not interchangeable — they work differently, attract patients at different stages of their decision, and perform better for different treatments. This comparison explains which to use when.

The fundamental difference: intent vs interruption

Google Ads captures existing demand. When someone types 'dental implants Manchester' into Google, they have already decided they want implants and are looking for a provider. Your ad appears at the exact moment of peak intent. The patient is actively looking for you.

Facebook Ads create demand. When your ad appears in a patient's Facebook or Instagram feed, they were not looking for a dentist. You interrupted their scroll with something that — if your targeting and creative are right — catches their interest and makes them consider treatment they hadn't been actively searching for.

This is not a quality difference — it's a strategic difference. Both are valuable. The question is which is right for your goal at any given moment.

Head-to-head comparison

Factor Google Ads Facebook/Instagram Ads
Patient intent High — actively searching Lower — passive browsing
Cost per click Higher (£3–£18 for dental) Lower (£0.50–£3 typically)
Conversion rate Higher (high intent) Lower (lower intent)
Best for High-value treatments, emergency, local searches Cosmetic treatments, retargeting, reactivation
Creative requirement Text-based, keyword-matched Visual — image or video essential
Minimum viable budget £1,000–£1,500/month £500–£800/month
Speed to results Fast — enquiries within days Moderate — 2–4 weeks to optimise

Which to start with

Start with Google Ads if: you need patients now, you offer high-value treatments (implants, Invisalign, full-arch), or you're in a market where patients are actively searching for your specific treatments.

Start with Facebook/Instagram Ads if: you have good before/after content and offer cosmetic treatments with strong visual appeal, you want to retarget website visitors, or you want to reactivate your existing patient database at scale.

Run both when: you have a working Google Ads campaign and want to add scale and brand awareness. The two channels complement each other — Google captures existing demand, Meta builds future demand and re-engages warm prospects.

Where they work together

The most effective dental advertising strategies run both channels in coordination:

  1. Google Ads captures patients actively searching for treatment
  2. Meta retargeting catches patients who visited your website but didn't enquire
  3. Meta lookalike campaigns find new patients similar to those who converted via Google
  4. Meta brand awareness campaigns build recognition so patients recognise you when they start searching on Google
