I have used Dr Tillman for years and there was always an issue for the work he has done on me always . So I decided to change dentist and I am very happy with my new dentist now. I have been with my new dentist for 2 years never had any problems. Dr Tillman is known for using cheap materials that why his work has to be redone almost every couple of years! My advice run from this dentist as far as you can.
