How many Google reviews does a dental practice need? What 333 practices show

"How many reviews do we need?" is one of the most common questions practice owners ask, and the usual answers are either a guess ("at least 50") or a national average that has nothing to do with the three practices a patient actually compares you against. So we looked at real local data instead.

The data

We analyzed public Google ratings and review counts for 333 operating dental practices in the markets DentalMarketScout has mapped: the Toronto area (139 practices), Peterborough and the Kawarthas (77), Tyler, Texas (74), and Ottawa (43). Data was collected between June and September 2026. Each practice is counted once, and no practice is named here.

Finding 1: almost everyone has great stars

• Average rating: 4.70. Median: 4.9.
• 85% of practices are rated 4.5 or higher.
• 68% are rated 4.8 or higher.
• Only 7% are below 4.0.

When two-thirds of the market sits between 4.8 and 5.0, a patient comparing three practices will usually see three near-identical ratings. The star rating stops being a differentiator and becomes a threshold: being below about 4.5 hurts you, but being at 4.9 instead of 4.8 rarely wins anyone over.

Finding 2: review counts vary enormously

• A quarter of practices have 13 reviews or fewer.
• The median practice has 61 reviews.
• The top quarter has 228 or more.
• The top 10% have over 540.
• 21% have fewer than 10 reviews; 44% have 100 or more; 21% have 300 or more.

This is where practices actually separate. A patient choosing between a 4.9 with 18 reviews and a 4.8 with 400 reviews isn't making a close call — the larger number reads as an established, busy, trusted practice.

Finding 3: low-volume ratings are noise

Grouping practices by review count shows why patients discount small numbers:

• Fewer than 10 reviews (71 practices): 75% have a perfect 5.0 — and 17% are below 4.0.
• 10–49 reviews (88 practices): 25% have a 5.0; 9% are below 4.0.
• 50–99 reviews (26 practices): 12% have a 5.0; 4% are below 4.0.
• 100–299 reviews (78 practices): average 4.79; 1% are below 4.0.
• 300+ reviews (70 practices): average 4.81; 1% are below 4.0.

With a handful of reviews, one happy or unhappy patient swings the score — which is why perfect 5.0s cluster at the low end and so do the worst ratings. Past roughly 100 reviews, ratings settle into a narrow, high band. Volume doesn't just look better; it makes your rating trustworthy.

So how many reviews do you need?

There's no universal number, because patients only compare you to nearby practices. A useful way to set your target:

1. Floor: get past 50 reviews as soon as you can. Below that, your rating is fragile and visibly thin next to established competitors.
2. Benchmark: find the top-quarter review count among the practices near you — in our data that's around 228, but in a small town it may be 80 and downtown it may be 600.
3. Target: aim to pass that local top-quarter number, and keep a steady pace afterward. A practice that stops collecting reviews slowly falls behind competitors who don't.

Review volume also feeds AI assistants: tools like ChatGPT lean on Google's business data when they recommend local practices. Our guide to AEO for dentists covers how ratings, reviews, and your website work together to get you named in AI answers.

How to grow reviews the right way

• Ask every satisfied patient, at the moment they're happiest — usually checkout, or a follow-up text the same day with a direct review link.
• Make it one tap: a short link straight to your Google review form, not your homepage.
• Don't offer incentives (discounts, gift cards, draws) and don't screen patients so only happy ones get asked. Both break Google's review policies and can get reviews removed.
• Reply to reviews, positive and negative. It shows prospective patients someone is listening, and a calm reply to a bad review often matters more than the review itself.
• Build it into the routine. A practice that asks consistently will out-collect one that runs a review push once a year.

Your review count lives on your Google Business Profile, so the rest of that profile matters too — our Google Business Profile guide for dentists covers categories, photos, posts, and the weekly upkeep routine.
