I just found DoctorOogle.com, a website that reviews and rates dentists of many specialties. Does anyone of you know of it and found their reviews accurate?

Last week, I went to take a look at one of the dentists that seemed promising, and found myself questioning the accuracy of such reviews. In the first visit, one of the receptionists said that the consultation was comprehensive and free of charge. However, the receptionmist I spoke with to make the consultation appointment said that the dentist can charge $68 if she deems it necessary (she would not have told me about the charge if I hadn't asked). Does anyone see this as a red flag?
