I won't go into great detail but STAY FAR AWAY from any dentist in Boston or the surrounding area with the last name Hart. I'm sorry if I'm blackballing another Dr. Hart but I wouldn't take the chance. The entire family practices -mainly because there are so many complaints about 1 member that another family member must take over in order to keep the operation running. They all have enormous files with the American Dental Association - practicing without a sufficient liscense, etc.
