Does a dentist need Saturday hours to rank in Google Maps? 430 listings in 22 cities

Dentists hear it from practice consultants, from scheduling software vendors and from the colleague across town who just added a sixth day: open on Saturday. Patients search when they are off work, Google favors a listing that is open when the search happens, and the practices at the top of the map pack are supposed to be the ones with the longest weeks. A four-day practice that closes Friday and Saturday is assumed to be giving the top spots away.

We tested it against the list itself. On October 8, 2026 we captured the Google Maps top 20 for “dentist” in 22 US cities, 11 large metros and 11 small cities, and read the weekly hours under every listing. After removing oral surgery practices, two lead-network listings and one listing we could not verify, 430 dental practices remained, 426 of them showing a full week of hours.

The belief did not survive the reading. 12 percent of practices in the top 20 list any Saturday hours. The top three look like the rest: 8 of the 66 top-three listings open on Saturday. And the most common week on the list is not a long one: 43 percent of practices are open four days.

Your benchmark

Open Google Maps, search “dentist” and your city, and read the hours under each of the 20 listings. Here is what the 22 cities looked like, counting the days each practice is open:

Days open per week (426 listings)	Share of listings	Median position	Listings in the top three	Median reviews	Median hours per week
4 days	43%	11	18	355	34
5 days	47%	9	41	607	42
6 days	8%	11	6	797	52
7 days	2%	10	0	1,030	119

The median practice in a top 20 is open 5 days and 39 hours a week. A quarter are open 34.5 hours or fewer, and three quarters 44 or fewer. The practice at position 1 opened on Saturday in 1 of the 22 cities; in 15 cities it kept a five-day week and in 5 a four-day week. Sunday is rarer still: 8 of 426 practices list Sunday hours, and none sit in a top three.

Saturday does not sort the list

Among the 49 practices that open on Saturday, most offer a morning; the most common Saturday line is 8 AM to 2 PM. Those 49 sit at a median position of 10. So do the practices closed on Saturday. Across all 430 listings the correlation between Saturday hours and position is 0.017, and on the 405 independent practices it is 0.004. What the Saturday practices do have is reviews: a median of 677 against 490. Split the sample into thirds by review count and the Saturday effect does not appear in any third.

The two kinds of market keep different weeks, so here they are split.

	Large metros	Small cities
Practices with hours	218	212
Open on Saturday	40 (18%)	9 (4%)
Saturday practices in the top three	7 of 33	1 of 33
Open four days	63	120
Open five days	116	84
Median hours per week	40	36
Median days open	5	4

In a metro, about one competitor in six opens on Saturday; Chicago had the most at 9 of 20. In a small city the Saturday practice is nearly absent. Five cities had no Saturday listing in the top 20 at all, and 16 of the 22 had none in the top three.

The four-day week is the small-city norm

The more useful number for an owner outside a metro is the four-day week: 120 of the 212 small-city practices, 57 percent, are open four days, and 167 of the 183 four-day practices in the whole sample close on Friday.

Does the fifth day go with a better position? In the small cities, five-day practices sit at a median position of 8 against 11 for four-day practices, and hold 21 of the 33 top-three slots against 11. In the metros the gap is 10 against 11.

But the fifth day comes with reviews. Small-city five-day practices carry a median of 512 reviews against 282, and across the whole sample being open on Friday goes with review volume at a rho of 0.332, stronger than any hours measure’s relationship with position. Friday hours against position is -0.085 across 430 listings, not significant; it clears the bar only in the small cities, at -0.166, and inside review thirds it clears the bar once, in the middle third, in the wrong direction. Total weekly hours give -0.117 across 426 listings, significant but weak, and days open -0.066, not significant; inside review thirds the weekly total is unrelated to position in two thirds and goes with lower positions in the middle one. A longer week and a larger review count travel together, probably because both come with practice size, and the review count is the one that tracks position.

Reviews, again

The dental shape we measured in September held on a new list of cities: rating is a floor, volume is the ladder. The median rating is 4.9 with no relationship to position (rho -0.048). The median top-three practice has 876 reviews against 386 at positions 13 to 20, a rho of -0.359 across 430 listings. In metros the top three carry 1.18 times their own market’s median listing; in small cities, 2.22 times. Read the 20 review counts in your own pack, take the middle one, and multiply by 1.2 in a metro or 2.2 in a small city.

One lead: open at the moment of the search

We searched on a Thursday at 9:21 in the morning Eastern time, 8:21 Central and 7:21 Mountain, when 394 of the 426 practices with hours were open. The 32 that were closed at that moment, most of them practices that open at 9 or later and three that close all day on Thursday, sat at a median position of 15 against 10 for the open ones, and 65 of the 66 top-three listings were open. The correlation between being open and position is -0.199 across 430 listings, -0.206 on independents, and it holds inside the two most reviewed thirds of the sample, at -0.222 and -0.26, which no other hours measure in this study did.

That is the mechanism the Saturday advice rests on, and it showed up in the one place it could. It is a lead rather than a finding: an early opening is confounded with everything else about a practice, and a morning search cannot say what happens at 7 in the evening or on a Saturday.

What changed in verification

The first run tagged 37 listings as brand locations. Three phrases written to catch national names, “family dental care”, “dental associates” and “gentle dental”, are also ordinary practice names and had tagged 14 listings of independent practices in 9 cities; brands are now matched by website, and 25 locations remain, holding 1 of the 66 top-three slots. The first run also kept three oral surgery practices filed under Dentist or Dental implants provider, kept a one-review listing named for another city with no website, and excluded a general practice with 1,413 reviews because Google files it under Medical clinic. A third pass fixed the open-now flag, which had counted listings showing “Opens soon” as open. Every hours figure was recomputed on independents alone and did not move.

What to do with this

• Do not add a Saturday to rank. 88 percent of the practices in a top 20 are closed on Saturday, and the 12 percent that are open sit no higher.
• A four-day week is not disqualifying. 18 of the 66 top-three listings keep one. In a small city it is the majority of your competitors.
• List a full week of hours, and if you open early, say so. The one hours signal that went the belief’s way was being open when the search happened.
• Spend the effort on reviews. Volume is the only measured factor that tracks position, and it is what the longer-week practices had in common.

Limits: what this can and cannot tell you

Measured: the listed weekly hours, open status at the moment of the search, review counts, ratings and positions of 430 dental practice listings in the Google Maps top 20 for one query in 22 cities on one Thursday morning, with every comparison repeated on independents and inside review thirds.

Not measured: searches on a Saturday, in the evening or on a Sunday, when the open-now mechanism would operate against most of the list. Whether listed hours match the hours the front desk keeps. Appointment availability, which is what a patient wants from a Saturday.

Range restriction: every practice here already appears in the top 20. The study can say whether Saturday hours or a longer week sort the list, not whether a four-day practice with few reviews is kept off the list in the first place.

Other explanations: the four-day practices are smaller by the one proxy we have, review count. A practice that grows may add both a fifth day and a few hundred reviews, and this design cannot separate the two. Website measures were read for 328 of the 430 practices and are not part of the hours finding.

The number to write down

The median practice in a dental map pack is open five days and 39 hours a week, and 12 percent of the list opens on Saturday. The top three keep the same week as everyone else and carry 876 reviews. Read the hours in your own pack, keep the week you can staff, and put the time into reviews.
