When Dr. Brinbaum fills a tooth you know that the cavity is gone, the filling is secure and that there is no risk of infection or error. I've had Dr. Birnbaums filling for over 20 years and they have not had to be replaced. He is incredibly thorough. When I leave his office I am confident that I have received first class service. I also get my teeth cleaned there, and the service is excellent. I'd give 5 stars if they let me!
