Top notch in quality, professionalism, competence, and most of all caring. The staff is friendly and Dr. Hart takes the time to talk to you and find out what your concerns are. She does a through check for oral cancer, gums, cavities, and checks or grinding. There are no lectures on not flossing or not having been to a dentist for a long time. Dr. Hart's approach to care is conservative with emphasis on educating you on the process and making sure you are comfortable throughout.
I did NOT feel anything when I had my cavity filled. She did a great job making the broken down tooth look like a tooth again. I also get complemented for my "beautiful smile" from people I meet ( Dr. Hart did four venners on my four front teeth. ) All in all, I would rate Dr. Sarah Hart as a kind, caring dentist extraordinaire! Only negative: the office phone # listed is wrong; It should be: (617) 492-1999.
