I had a negative overall experience with Dr. Sawyer. He did three fillings for me that were all sensetive within a week afterwards. He was very good about checking up on them without charging me but kept saying that the sensetivity would go away soon. Well, a year and a half later I had to get them all redone by a different dentist and two of them had quite a bit of decay underneath.
I am aware that composite fillings are prone to problems and I'm sure he did the best he could. Everyone who works there, including Dr. Sawyer, are friendly and respectful, but I wouldn't go back to his office for anything but a teeth cleaning.
