Manipulation score

How this score works
The score estimates how strongly this place's review record matches known manipulation patterns, from 0 (no signs) to 100. Verdicts: Clean below 40, Suspicious from 40, Likely Manipulated from 70; Review Drive when the flags are mostly staff asking customers for named reviews. It rises with the share of reviews flagged and how suspicious each one is.
- Burst
- — an abnormal spike of five-star reviews in a single day compared to the place's usual pace.
- Low activity account
- — the reviewer has almost no other reviews, photos, or Local Guide history; throwaway accounts look like this.
- Duplicate text
- — the wording is nearly identical to another review of the same place.
Verdicts are statistical estimates based on public review patterns, not accusations. Full methodology, signal definitions and known limits →

There are two dentists there. Both are kind, and the other dental hygienists are also friendly. It's a dentist I want to keep going to, and I'm glad it's in my neighborhood. I also like that the waiting room TV has been showing Tom and Jerr...

I was nervous when I entered the stylish clinic, but all the women were beautiful, which made my heart beat even more. They suggested that I have tartar removed as well as having my cavities treated, and after the tartar was removed, my gum...

I went there because of oral problems, and after an X-ray, I was told I had a cavity, although it was unrelated. As for the actual treatment, they just said they would wait and see, and if I was still concerned, they would write a referral...

I went to the dentist because I chipped a tooth. They asked if I wanted it cleaned up, and when I said yes, they even filed down healthy teeth without giving me a proper explanation. It cost a lot of money and it took a toll on me mentally....

At my first appointment, I wrote on the medical questionnaire that I wanted it covered by my health insurance. Since they were my front teeth, they were the ones I was most concerned about, so I wanted them treated. I'd been thinking about...

I go there occasionally and they are very polite. Even if you call, it's difficult to make an appointment right away. Previously, I would receive a letter saying, "Please come back in about six months after your treatment," but this changed...

On the day of my appointment, my hay fever symptoms were so severe I had a runny nose and couldn't stop sneezing, so I called around 9am to cancel my appointment for after 2pm, thinking it would be a bother to bother them, but they said it...

My gums became swollen and painful while I was out, so I went to this clinic. I had to wait because they were fully booked, but they took an X-ray and explained that the swelling and pain were due to inflammation from periodontal disease. After adjusting my bite and disinfecting, I was given antibio...

I had been managing my periodontal disease with medication for some time, but my teeth became loose, and it became so difficult to eat that I was really worried. A friend recommended this clinic, and I decided to go for a checkup. The initial measurement of my periodontal pocket depth was painful, b...

It was a sudden request for treatment, but they kindly accommodated me. The doctor's explanation was very easy to understand, and I would want to come back even if it meant traveling a long distance. I highly recommend them.

I've been going to this clinic for over 10 years. The receptionists and dental hygienists are all very pleasant and friendly. The clinic director is my dentist, and he explains things clearly, like the structure of teeth and what's wrong. I've been to many dental clinics in the area, but I feel t...
