Have your doctors discussed root canal as an alternative instead of any extractions? If so, this usually doesn't require the need for hbot. As a last resort, would I want to have any teeth extracted until it was absolutely necessary, down to pulp, infected, etc then the 20/10 Marx Protocol hyperbaric oxygen treatments, and so forth. Radiation above a certain Gy, plus an injury, like Teeth extractions, can cause ORN, so can other injuries, like dentures, spontantaniously etc, but Extractions are the main cause with radiated head and neck cancer patients.

Good luck
