About Us

Dr. Thomas M. Sims, DDS

Through many various continuing education programs he has attended over the years, Dr. Sims has become well versed in many varieties of restorative dentistry including cosmetic and complicated dental procedures like full mouth rehabilitation and hybrid dentures incorporating the use of implants. He has always kept up with the new technologies that has created an easier and more comfortable means to deliver care to his patients.

Dr. Sims has always had the drive to continue to learn. One area that has always evaded him as well as the majority of other practicing dentists is understanding the world of TMD (temporomandibular joint disorders) and it’s associated cranial facial pain. Through his tireless search he feels he has found the answer and is excited about the new protocols he follows. He feels so strongly about this newly acquired body of knowledge that he has elected to open a practice treating these disorders . He joins a group of 67 (and growing) centers throughout the world following these same protocols. The approach he uses is innovative yet it is very holistic and practical. Dr. Sims believes that within time all dental and medical students will understand the concepts he currently employs. Because these disorders often overlap into the medical community the opportunity to once again develop a bridge between the medical and dental community has emerged.
