This dentist did crowns and fillings for me. I guess they were fine. It is hard for me to know how to judge. She suggested many times that I wear a night guard on my teeth to avoid grinding damage while I slept. It was very uncomfortable getting this fit and it never worked right. Other than that I had no real problems. I haven't had many other dentists in the area so I can't really compare that is an unfair question, I think, but I can't figure out how to leave it blank.
