Why do Google reviews matter for dental marketing?

Your Google review profile is the filter every other marketing channel passes through: patients who see your ad, mailer, or website check your reviews before they call. It isn’t one marketing channel among many. It’s the checkpoint every other channel has to clear.

“About three out of every four people that see your ad check your Google reviews before they make a decision,” Lefler said, speaking from his experience with client practices. “Doesn’t matter if you have a billboard, a referral program, you’re doing search engine optimization, you do print mail, you do social media.”

Independent research points the same way. BrightLocal’s Local Consumer Review Survey 2026 found that 97% of consumers read reviews for local businesses. For more numbers on how patients use reviews, see our roundup of dental review statistics.

Think about what that means in practice:

1. A potential patient sees your beautifully designed Facebook ad. They’re interested.
2. Before they call, they do what everyone does: they Google your practice name.
3. Your Google Business Profile pops up with your reviews, your rating, and what patients have said about you.
4. If what they see doesn’t inspire confidence, they move on to the next dentist.

Your ad worked perfectly. It got attention. But your review profile lost the patient.

How much marketing budget can a weak review profile waste?

Adrian estimates that a weak review profile can waste half of a practice’s marketing budget. He described a practice with 50 reviews, many of them below four stars, launching a big campaign:

“If you go to market and you’ve got 50 reviews and half of them are junk, they’re below four stars, your average rating’s under four, and you don’t have a lot compared to other dentists, and you spend $100,000 on a marketing campaign, you’re going to lose probably at least $50,000 in spend just because people saw your message and checked your reviews and said, ‘Yeah, I’m not going there.'”

Half your marketing budget, gone. Not because the ads didn’t work. Not because people didn’t see your message. But because when they did their due diligence, your review profile didn’t measure up.

The table below shows how that plays out at different review levels. The 100 review, 4.5 star mark is the minimum to be “ready to spend.” The higher tiers are where marketing starts converting efficiently.

Why do reviews matter more now than they used to?

Reviews matter more now because patients compare practices side by side before they ever visit your website. There’s so much social proof baked into how people make decisions that your Google Business Profile can be one of your strongest trust signals.

When someone searches for a dentist, Google shows them a map with local practices. Each listing displays the practice name, star rating, and review count. Patients make split-second judgments based on those numbers before they ever click to learn more.

A practice with 47 reviews and a 3.8 rating sits next to one with 312 reviews and a 4.9 rating. Which one inspires more confidence at a glance?

That’s why reviews matter beyond rankings. As we explain in our article on SEO tips for dentists, getting found is only part of the equation. Giving patients the confidence to call is another. Even when your map position stays the same, a strong review profile can help turn that visibility into calls and appointment requests.

The AI layer adds another consideration. When patients ask tools like ChatGPT or Gemini to recommend a dentist, those answers may draw on what your reviews actually say, not just your star rating or review total. We cover this in more detail in our look at how AI tools read your reviews.

All of this helps explain why Lefler described your Google Business Profile as the “end all be all filtering system of all the marketing that you’re doing.” Your marketing can bring potential patients to that profile, but what they find there helps determine whether they call, book, or keep looking.

Should dentists build reviews before running ads?

Yes. Get to at least 100 Google reviews with a 4.5-star rating or higher before putting serious money into ads or SEO, because every channel sends patients to that profile. If you’re a new practice or one that hasn’t prioritized reviews, resist the temptation to pour money into advertising first.

“When you start marketing, the first thing you do is you make sure your client or you or whoever has a plan to build their Google review profile because it’ll improve all of the other marketing that you do,” Lefler advised.

The sequence matters:

1. Build your review foundation first.
2. Reach at least 100 reviews with a 4.5 or higher rating.
3. Then invest in ads, SEO, and other marketing channels.

Follow that order and your conversion rates will be dramatically better. You won’t be pouring money into a leaky bucket.

Already running ads? Don’t stop them if they’re working. Start automated review requests alongside your campaigns and watch your conversion rate improve as your profile grows. Every new review makes the next ad dollar work a little harder.

How do you build a review profile that supports your marketing?

You build it with a simple system you run every day, not a big budget. Building a strong review profile comes down to asking consistently and making it easy for patients to say yes.

• Ask at the right moment. The best time to request a review is right after the appointment, while the patient is still in the office or has just left. Timing matters enormously.
• Make it frictionless. Send a direct link to your Google review page by text message. Every extra click reduces completion rates.
• Automate the process. Connect review requests to your practice management software so they go out after every appointment. Consistency beats sporadic efforts.
• Respond to every review. Thank positive reviewers and reply thoughtfully to negative ones, without confirming the reviewer is a patient or mentioning treatment. Learn how to respond to dental Google reviews the right way.
• Focus on recency. A steady stream of new reviews matters more than a large pile of old ones. Patients want to know what the experience is like now, not three years ago.

One rule ties it all together: ask every patient the same way. Don’t offer patients rewards for reviews, and don’t ask only the happy ones. Selective asking and incentives are two of the most common review mistakes practices make.

The Bottom Line

Fix your review profile before you scale your spend. Google reviews aren’t glamorous. There’s no viral potential, no cutting-edge technology, no exciting creative work. But they’re the foundation everything else is built on.

Google reviews marketing for dentists comes down to one rule: fix the profile patients check before you pay to send them there.

Before you spend another dollar on marketing, take an honest look at your Google Business Profile:

• Count your reviews.
• Check your rating.
• Read what patients are saying.

If what you see wouldn’t convince you to become a patient, fix that first. Reviews are also the center of any broader dentist reputation management plan, so the work pays off well beyond your ads.
