I had a very similar experience at this dental office. They quoted extremely high prices for two cavities (which I considered to be routine type service) if I wanted the non-metallic fillings. I checked with the insurance company and they said they covered it like 80%. When I questioned the dental office, they said the insurance company doesn't cover it. I checked again with the insurance company and figured out that they do cover it. Essentially the dental office was going to overcharge me about $400 for two cavities and some other 'maintenance' type procedure. I am trying to get a new dentist at the moment. I don't know what's going on in this office but it doesn't smell right. Also, the hygenist who cleaned my teeth was very unprofessional. She clearly had a cold and was coughing all over. She also did a very poor job of taking x-rays as she kept causing me a lot of pain in the process.
