Welcome to Kerr Dental Associates - Plymouth MA Dentist Dr. Stephen Kerr moved to Plymouth in 1985 and opened his practice on Water Street near East Bay Grille and Plymouth Rock. His vision has been to create a dental experience that patients find friendly, knowledgeable and sometimes even fun. Kerr Dental Associates is a General Family Practice that provides exceptional family dentistry and cosmetic dentistry to adults and children using modern technology. Dr. Kerr practiced at the Water Street location for 25 plus years. The Pinehills office opened in 2010. It was perfect timing as Dr. Kerr was outgrowing his space at the Water Street office and Kerr Dental Associates was established.
