How many Google reviews a dental practice needs to show up in Maps, measured across 22 cities

Ask a practice manager what it takes to show up when someone searches “dentist” in their city and the answer is usually a version of the same belief: you need hundreds of reviews and a rating that starts with 4.9. It is repeated by review software vendors, by marketing agencies, and by dentists who have watched a competitor climb past them.

We wanted to know whether the practices that actually occupy those positions look like that. So on September 2, 2026 we captured the Google Maps top 20 for “dentist” in 22 US metro areas, from Phoenix to Pittsburgh, and measured every practice that appeared: 440 listings, 437 practices with a website we could read, and 426 distinct websites behind them.

The belief turns out to be half right, and the half that is wrong is the half everyone works hardest on.

The benchmark: 545 reviews

Across the 437 practices in the Maps top 20:

• Fewest reviews: 17
• 25th percentile: 337
• Median: 545
• 75th percentile: 842
• 90th percentile: 1,252
• Most: 4,730

If you run a practice, that middle number is the one to hold on to. Half of the practices that show up in the top 20 have fewer than 545 Google reviews and half have more. The mean is 667, pulled upward by a handful of practices with thousands, which is why the mean is the wrong number to plan around.

The floor is low but real. Only 4 percent of top 20 practices have fewer than 100 reviews, and only 11 percent have fewer than 200. Below that line, appearing at all is rare in these markets. Above it, position depends on something else.

Rating is the floor, not the ladder

Here is the half of the belief that holds: the top 20 is a room full of near-perfect ratings. The median rating is 4.9. Seventy-nine percent of practices are at 4.8 or higher, 61 percent are at 4.9 or higher, and 13 percent sit at a flat 5.0. The lowest rating in the entire sample is 3.9, and it appears once.

Here is the half that does not: rating has nothing to do with where in the top 20 a practice lands. Practices in positions 1 through 3 have a median rating of 4.9. So do practices in positions 13 through 20. Every band in between is also 4.9. The correlation between rating and position is 0.109, which is statistically detectable at this sample size and, if anything, runs slightly the wrong way: the practices at the very top are marginally more likely to have a 4.8 than a 5.0, presumably because more reviews bring more critics.

The practical reading is that rating is a door, not a staircase. You need to be through it. Once through, polishing a 4.8 into a 4.9 is not what moves you up the list, and the practices that have done the polishing are not sitting higher than the ones that have not.

Review volume is the ladder

Volume is a different story, and it is the finding a practice can act on.

Maps position	Practices	Median reviews
1 to 3	66	769
4 to 7	86	627
8 to 12	109	548
13 to 20	176	448

The median practice in the top three has 769 reviews. The median practice in the bottom third of the list has 448. The relationship holds across the whole sample as a rank correlation of -0.254 between position and review count, significant with 437 practices, though weak enough that plenty of individual practices break the pattern.

Weak and real is the honest description. Review volume is not the whole explanation of position, and it is not proof that adding reviews causes movement. But among the things we could measure, it is the only one that separates the top of the list from the bottom, and it separates them by roughly 300 reviews.

The website does not enter into it

This is the number we expected to go the other way.

For 352 practices with a readable sitemap, we counted pages. The median dental practice website in the Maps top 20 has 72 pages. A quarter have 44 or fewer. Sixty-two percent have fewer than 100. Compare that with the median top ten HVAC website we measured last week, which carried 378 pages, and the dental field looks lean.

More important, site size has no measurable relationship with Maps position. The correlation is -0.015 across 352 practices. That is not “too small a sample to tell,” which was the limitation of our HVAC study with 57 businesses. At 352, an effect of any practical size would be visible, and there is none.

Blogging fares no better. The median practice has exactly 1 page under a blog, news or resources path. Fifty-nine percent of homepages link to a blog, and of the 225 practices where we could count what was behind that link, 112 had one post or none. Publishing volume, publishing recency, homepage word count, page weight: none of them track position.

None of this says a website does not matter for other things. It says that if the goal is a better Maps position for “dentist,” the website is not where the evidence points.

Who you are actually competing with

One structural finding surprised us. In our HVAC study, a third of Google’s page one was not a local business at all: directories, marketplaces, manufacturers. We expected the dental Maps results to be crowded with national chains.

They are not. Of 437 practices, 3 were locations of a brand appearing in three or more of our markets. The rest are independent or regional. Only 3 of the 440 raw listings lacked a website entirely. For a practice owner, that is good news of a specific kind: the slots you are competing for are held by practices like yours, not by aggregators you cannot displace.

What the field says about itself

We also read every homepage for the language it uses. The median practice makes 3 superlative claims on its homepage, such as best, top-rated, premier or award-winning. The median number of checkable numeric claims, such as years in practice or patients served, is 0. Fifty-three percent make no numeric claim at all, and 87 of 417 practices make three or more superlatives while offering no number a patient could check.

That pattern is the belief system of the category on display: reputation is asserted in adjectives, while the one number patients actually use, the review count, sits on Google rather than on the practice’s own site. Only 15 percent of practices publish review or rating structured data on their homepage, even though 82 percent publish some structured data and reviews are the currency of the whole list.

Two other adoption figures for practices measuring themselves: 66 percent offer online booking from the homepage, and 8 percent run a chat widget.

Limits: what this cannot tell you

Every practice here already ranks in the top 20. That means this study can describe what the top 20 looks like and how its members differ from each other. It cannot say what separates them from the practices that do not appear, because those practices are not in the data. If a review threshold is a gate you must pass to appear at all, the sample would show everyone past the gate, which is what it shows.

Results were captured once, on September 2, 2026, with one query per metro and Google’s default location for that metro. Maps results vary by the searcher’s exact position, time of day and device. This is one photograph of 22 cities.

Ratings and review counts are as Google displayed them at capture time. Page counts come from published sitemaps, and 85 practices had none we could read; they are reported as missing, not as zero. Blog volume counts sitemap URLs under a blog, news, article or resources path. Claim counts are phrase counts on the homepage only.

We did not measure Google Business Profile completeness, photo counts, response rates to reviews, review recency, category selection, or proximity to the map center, and any of those could carry more of the explanation than review volume does. Correlation here describes what co-occurs among practices that already rank. It does not establish cause.

The number to write down

If you run a dental practice and want to know where you stand: the median top 20 competitor in a large US metro has 545 Google reviews and a 4.9. If your rating is already 4.8 or better, you are through the door with 79 percent of the field, and polishing it further is unlikely to move you. If your review count is under 337, you are below three quarters of the practices that appear, and volume is the only measured factor that tracks position.

The full dataset, including every listing, every measurement and the three listings we could not measure, is below. If you rerun it for your own metro and get a different answer, we would like to know.
