He said the process was relatively painless. He had to provide evidence of having completed an ADA program in Oral and Maxillofacial Surgery and had an interview with a few members of the credentialing board. He said that the board was composed of 2 general surgeons (one of whom was the chief of surgery), 1 anesthesiologist, 1 plastic surgeon, 1 ENT and 1 OMFS, in addition to hospital administrators and a "lay member".
Curiously, you'll notice some random general/restorative dental procedures on the core credentialing list - like crown and bridge preparation!
