Hi cooldown, I also think the condition you are referring to is osteoradonecrosis(thank you Eileen). There was a recent post by Lenny that touches on this and I think Lenny states that it only occurs in about 5% of patients.I think it is more of a long term complication from radiation. I also have had several teeth pulled and many root canals without Hyperbaric oxygen.I don't know what specific complication you have with your teeth but maybe you can let us know what your condition is called for us to be more helpful.Pulling healthy teeth I don't recommend, but you must deal with dental issues forever and sometimes for the better of all a few must go.
