A Modern Dentistry Servicing New London CT


Cutting-edge dentistry meets small-town charm in New London’s historic district.

Thames River Dental grand opened in 2016, and we’re proud to say that the newest dental office in town is also (in a sense) the oldest! Our historic gothic revival building dates back 120 years to simpler days. Much has changed since then – modern advances make visiting the dentist a reason to smile. But some things haven’t changed, like our old-world charm, friendly attitude, and attention to detail. At Thames River Dental, we provide services for all ages. Including tooth replacement, preventative care, restorative and cosmetic dentistry, periodontal treatment, emergency treatment, root canals, extractions, Invisalign, and so much more!


Gladly accepting new patients!
