At The Dentists Insurance Company, we promise to only protect dentists, protect them better than any other insurance company and be there when they need us. On July 1, 1980, in a climate of skyrocketing professional liability insurance premiums, a bold group of dentists took action and created The Dentists Insurance Company, TDIC. Those three promises made over 40 years ago when TDIC was founded are just as true today. We’ve now grown to serve more than 24,000 dentists across 15 states, earning an A (Excellent) from AM Best for more than 28 consecutive years and the endorsement of several state dental associations along the way.
