I found out that Dana-Farber's H&N department does not have dental oncologists on staff. There are two dental oncologist at associated Brigham & Women's Hospital.

However, they only see patients currently undergoing treatment. I then asked to whom the dental oncologists refer post treatment. The answer was back to the patient's general dentist.
