The Missouri Dental Board and the ADA do not recognize the treatment of TMJ (neuromuscular dentistry) or cosmetic dentistry as a specialty.
Further, the ADA does not require any additional training of dentists who perform or advertise these procedures. Cosmetic dentist Dr. Quigless practices general dentistry in St. Louis, Missouri but he has many continuing education hours in cosmetic and TMJ therapy procedures at the prestigious Las Vegas Institute for Advanced Dental Education.
