The honest answer is that there is no magic number, but there is a threshold and there is a rhythm, and most practices are wrong about both.

The threshold

Below roughly twenty five reviews you look new or inattentive, and individual bad reviews carry enormous weight because your average swings on every entry. Getting to twenty five is the first real goal.

Between twenty five and one hundred you look established. Your average stabilizes. A single unhappy patient can no longer move your rating meaningfully.

Above one hundred you start to look like the obvious choice in a small market, and above two or three hundred you are effectively unassailable locally. One client of ours, a plumbing company rather than a practice but the dynamic is identical, sits at over one hundred fifty reviews at a perfect five star average. Competitors do not out-market that. They just lose to it quietly.

So: twenty five to be credible, one hundred to be strong, and past that it becomes a moat.

The rhythm matters more than the total

A practice with four hundred reviews where the newest is from eighteen months ago reads worse than a practice with eighty where six arrived this month. Patients look at dates. So do the systems that summarize your practice for a searcher.

A steady trickle is the goal. Four to eight new reviews a month, forever, beats a burst of forty followed by silence. Bursts also look engineered, because they are.

How to get them without being annoying

Ask at the moment of relief. Right after the crown fits, the pain stops, the treatment finishes. Not at checkout while someone is thinking about a bill.

Ask by text, not email. Text open rates are not comparable to email and never have been. A short message with a direct link, sent within an hour of the visit, converts many times better than anything else.

Ask by name and let one specific team member own it. Diffused responsibility means nobody asks.

Do not ask everyone. Ask the patients who just had a good experience. That is not gaming anything, it is timing.

The thing you cannot do

You cannot offer anything of value in exchange for a review. Not a gift card, not a discount, not entry into a drawing, not a free whitening. This is not just a platform policy. In the United States the Federal Trade Commission’s rule on consumer reviews and testimonials, which took effect in October 2024, makes incentivized and fabricated reviews an enforcement matter with penalties that run into tens of thousands of dollars per violation.

You also cannot write them yourself, have staff write them, buy them, or selectively route unhappy patients away from the public review while sending happy ones to it. That last one, sometimes sold as reputation gating, is explicitly a problem now.

If a vendor offers to produce reviews for you, that vendor is offering to create your legal exposure.

Negative reviews are an asset, handled correctly

A perfect five point zero with three hundred reviews sometimes reads as filtered. A few fours with thoughtful public responses read as human.

Respond to every negative review within twenty four hours. Do not argue, do not disclose anything about the person’s care, do not mention that they were a patient. Acknowledge, take it offline, name the person handling it. You are not writing to the reviewer. You are writing to the next fifty people who will read that exchange while deciding whether to call you.
