mawalton, My husband didn't have any tooth extractions but he does have a spot at the right base of the tongue where they did both surgery and apparently extra radiation. The tissue is not healing there. He is going to start hyperbaric oxygen therapy in a week. This is different than your situation though. What have your doctors said about it? Have they offered any solutions? That would be really rough to go that long without a solution in hand. I wish you luck in finding an answer. Connie.
