Dr. Tamura's office is very clean and he uses a lot of high tech gadgetry (e.g. DVD goggles for longer dental work, lasers for teeth cleaning). I had a crown placed for a molar and all my silver fillings replaced in addition to regular cleaning. The major thing I noticed was the excessive cleaning required. My insurance only covered 2 cleanings a year. They scheduled me for 4 a year. Also, I got the feeling he was out for money at times. I recommended a co-worker who mentioned that when he went in, Tamura recommended that he get all his silver fillings replaced with the natural colored fillings, and get a crown for his molar as well. It seems like he had a cookie cutter approach to new patients. The staff is real friendly. My wife also went to Tamura for a while. He recommended the same set of procedures for her as well (fillings, excessive cleanings even though she had 1+2's on her checkups). The major turn-off for Tamura is his attitude towards women. I have seen him yell at his assistant Janet at least a couple of times, once during the crown replacement. It was in a very unprofessional manner. The teeth that had its fillings re-done were really sensitive for a while. My co-worker and wife also shared these experiences.
