Google Ads for dentists: the numbers, and why they look worse than they are
Google Ads for dentists is an expensive channel that converts unusually well:
| Metric | Dentists | All industries |
|---|---|---|
| Click-through rate | 5.66% | 6.64% |
| Cost per click | $8.00 | $5.42 |
| Conversion rate | 10.67% | 8.18% |
| Cost per lead | $72.97 | $66.69 |
A dental click costs about 48% more than the cross-industry median, but converts about 30% better — so the cost per enquiry lands only slightly above average. Google Ads for dentists is a comparatively efficient channel, which is not true of every expensive vertical.
The decisive question is what a patient is worth to you. A single new patient attending twice a year for several years is worth hundreds or thousands. Against a $73 enquiry cost, that works comfortably. A one-off whitening at $200 does not, once you account for the enquiries that never book.
So the arithmetic isn't "can I afford Google Ads" — it's "which treatments can I afford to advertise".
Advertise treatments, not "dentist"
The biggest waste in dental accounts is bidding on the category.
"Dentist" and "dentist near me" look obvious and are brutally competitive — you're bidding against every practice in the city, including corporate groups with far deeper pockets, for traffic that is largely looking for a routine check-up they'll book at whoever is nearest.
Routine check-ups are a local SEO problem, not a paid search problem. Proximity decides them and the margin doesn't support an $8 click. That's covered in local SEO for dentists.
What paid search is genuinely good for is high-value treatment, where patients research and travel:
| Treatment | Why it works in paid |
|---|---|
| Dental implants | High value, patients compare and travel |
| Invisalign / clear aligners | High value, strong search demand |
| Cosmetic dentistry, veneers | Discretionary, actively researched |
| Full-mouth rehabilitation | Very high value |
| Emergency dentist | Urgent, high intent, converts immediately |
One campaign per treatment, each with its own budget. Implants and emergency appointments should never compete for the same pot — they have different values and different urgency.
Emergency is the most underrated campaign
"Emergency dentist near me" converts at rates most treatments can't match, because the patient is in pain and deciding in minutes.
Three things make it work:
Answer the phone. The practice that answers first very often gets the patient. This is a front-desk problem more than an advertising one.
Match hours to the campaign. If the ads run at 9pm, someone needs to handle a 9pm call — or the ad should state your next available slot honestly.
Dedicated landing page. Not the homepage. The page should state how quickly you can see them, what it costs, and give one tap to call.
Negative keywords, dental edition
At $8 a click, waste adds up quickly. A starting list:
free, cheap, NHS (if private, and vice versa), jobs, salary,
assistant, hygienist jobs, school, course, training, insurance,
how to, DIY, at home, kit, reddit, plus every competitor practice
name you don't want to pay for.
Review search terms weekly. Dental attracts an unusual amount of job-seeking and DIY-remedy traffic.
Track calls, or you're guessing
Dental enquiries come by phone far more than by form. If you only track form fills you're measuring the minority and optimising against it.
Use call tracking with a duration threshold — 60 seconds is reasonable — so a misdial doesn't count as a conversion. Then Google's bidding can learn from what actually produces patients.
Link Google Ads to GA4 so you can see what happens after the click, not just that it happened.
Budgeting Google Ads for dentists
Work backwards. At a $72.97 cost per enquiry, 30 conversions a month — the rough threshold for automated bidding to learn — implies about $2,200/month.
If that's out of reach, narrow rather than thin out: one treatment, one tight radius, restricted hours. A small budget concentrated on implants in a five-mile radius beats the same budget spread across every treatment in the city.
Below roughly $1,000/month, put the money into the Google Business Profile first.

Compliance rules that apply to Google Ads for dentists
Dental advertising is regulated in most countries, and Google's approval process will not enforce your local rules for you.
Common restrictions: claims about outcomes, before-and-after imagery, "best" or "painless" superlatives, testimonials, and pricing that omits conditions. Check your dental council's advertising guidance before writing ad copy — a complaint is far more expensive than a rewrite.
FAQ
How much do Google Ads cost for dentists? About $8.00 per click and $72.97 per enquiry on average. Competitive city centres run higher.
Are Google Ads for dentists actually worth it? For high-value treatments — implants, Invisalign, cosmetic, emergency — yes. For routine check-ups, usually not; proximity decides those and local SEO is the better route.
What budget do I need? Around $2,200/month to reach ~30 conversions. Below $1,000, fix the profile first.
Should I bid on "dentist near me"? Generally no. Brutally competitive, and the intent is routine care that local SEO wins more cheaply.
Google Ads or local SEO for a dental practice? Both, in that order of fixing: profile first because it's free and improves paid conversion too, then ads for high-value treatments.
