I have been to Dr. Biles for prophylaxis. The staff are very friendly and the 1st appointment is very thorough. They spend 3-4 hours doing digital x-rays, checking out your teeth, and going through your history. I was impressed by the treatment plan they produced at the end of my visit. I am now considering the second part of my plan, which is to remove my mercury fillings and replace them with composites. Dr. Biles is very much behind this procedure and encourages it. His facility is supposedly set-up for extremely safe removal. I have had no problems with them concerning my insurance and the receptionist is very helpful.
