When we talk to dentists, one question comes up again and again:

“Do Google reviews really make that much of a difference?”

Some dentists believe reviews are the single biggest driver of new patient growth. Others think reviews are more of a “nice-to-have” — they make your practice look good, but they don’t actually bring patients through the door.

We wanted to find out who’s right.

Because we do dental marketing for hundreds of practices across the U.S. and Canada, we have a unique window into what really drives new patient growth. Our Scorecard software tracks each practice’s Google reviews, star ratings, and the number of new patient calls they receive every month.

That means we’re not guessing, we can actually see how reviews impact call volume in real-world practices.

What we found was eye-opening.

What you’re looking at here is real data pulled from hundreds of dental practices across North America. Each blue dot represents a single practice, showing two things: how many Google reviews they have (on the horizontal axis) and how many calls per month they received from new patients (on the vertical axis).

The green line shows the overall trend — and it’s pretty clear. As the number of reviews goes up, so do the calls.

Practices with just a handful of reviews see relatively few calls, while those with hundreds (or even over a thousand) are consistently generating far more new patient inquiries.

• Under 100 reviews: practices often struggled to get traction, stuck at fewer than 200 calls per month.

• 300–500 reviews: call volume often doubled or even tripled. Imagine going from 150 calls a month to 400 — that’s a game-changer.

• 500+ reviews: this is where the real payoff comes. Offices in this range often saw 400–600 calls per month.

If you’ve got 500 Google reviews but your rating is only 4.4 out of 5, does it still work? The answer is no.

It’s not enough to just have a big review count. Patients care deeply about the quality of those reviews. In fact, once a practice’s rating drops below 4.7 stars, we see a sharp decline in call volume, even for offices with hundreds of reviews.

Think about it from the patient’s perspective: they’re not just asking “How many people reviewed this dentist?” They’re really asking, “Do people actually trust this dentist?”

Here’s the kicker: the practices winning the most patients aren’t just the ones with a lot of reviews, they’re the ones with a lot of reviews and high ratings.

This combo doesn’t just drive more calls, it makes patients far more likely to book, because the trust is already there before they even dial.

So let’s say you’ve done the hard work. You’ve built up a high star rating and hundreds of Google reviews.

That’s great for getting more calls — but here’s another question:

Does it also improve the number of patients who actually book once they call? The answer, again, is yes.

Here’s why:

Back in the Yellow Pages days, things worked differently. A patient would pick up the phone first, then do their “research” afterward — asking friends, checking around, maybe reading a pamphlet.

But today? The research happens before the call.

By the time a patient dials your office, they’ve already checked your Google reviews, compared you to other dentists in the area, and made a mental decision about whether or not they trust you. The call is no longer about deciding if they want your practice. It’s about confirming their choice.

So if your practice has a high star rating and a strong number of reviews, the dynamic changes completely. Patients calling you are essentially pre-sold. As long as your front desk team is friendly, helpful, and professional, it’s a done deal. The appointment is yours to lose.

Now compare that to a practice with a weaker online reputation — maybe a 4.3 rating and only a handful of reviews. Those calls feel very different. Patients come in cautious. They’re not fully convinced. They’re testing you. And that means your front desk staff has to work much harder to persuade them that they’ve made the right choice.

The big difference? With a strong online reputation, trust is already in place before the call ever happens.

You can spend thousands on ads, dental SEO, or direct mail, but when a prospective patient Googles your name (and they always do), the first thing they see are your reviews. If what they find isn’t impressive — low count, mediocre rating, or no recent activity — every other marketing effort you’re making instantly loses impact.

That’s where social proof comes in. Reviews are a big part of it, but so are video testimonials, before-and-after photos, and even local awards or media mentions. These elements work together to build trust at the exact moment patients are deciding where to book.

Getting the phone to ring is only half the battle. The real growth happens when you can convert those calls into scheduled appointments and strong social proof is what tips the scale in your favor, especially when a patient is comparing you to the office across the street.
