I had a filling put in and the filling fell out after two months. The dentist did not do a thorough job. Dr. Ringgenberg was out of town when the filling fell out, so I had the filling redone by another dentist and Dr.Ringgenberg refused to pay for the filling. Even though Dr. Ringgenberg was at fault for my filling, he refused to help me out. I would not recommend this dentist if you need anything more than a cleaning done.
