The Fine Print: Professional Research Services contacted more than 1,000 licensed general dentists and dental specialists in Rhode Island and nearby Connecticut and Massachusetts. PRS asked which dentists they would recommend across Rhode Island and outlying areas. Each dentist recommended up to three colleagues in each specialty. Once the ballots were complete, each nominee was evaluated based on the survey results, the legitimacy of their license, and their current standing with the Rhode Island Department of Health. Some dentists have more than one location. Call their office for additional information.
