Totally incompetent - Seven visits for a single crown that continued to not remain in place. Ms. Coyne recommended surgery and a bridge after her numerous unsuccessful attempts at installing a simple crown. Went to another dentist and had the same crown installed and three years later that crown has not come loose. Ms. Coyne refused to refund any money for her incompetency and her inability to install a crown. Dr. Coyne is incompetent and unethical. Stay away from this so called dentist !
