Specialist care: endodontics, periodontics and oral surgery
A Tooth Company has specialists on staff as well as general dentists, so several treatments that a general practice would refer out are done in house.
Endodontics - root canal therapy, using "3D imaging, surgical microscopes, and the innovative GentleWave system". Those three are significant: 3D imaging (CBCT) shows root canal anatomy a standard x-ray misses, a surgical microscope allows the canals to be treated under magnification, and GentleWave is a fluid-based cleaning system used as an alternative to conventional instrumentation. The endodontist is Dr. William Cheng, DMD, MS.
