I needed a tooth extraction in 2011, and all my doctors, oncologist, ENT, Oncology dentist said I needed HBOT, with the 20/10 Marx protocol. I need more extractions, actully all my teeth, are black, down to the gum line, and causing too many infections, abcesses, with different doctors now, say I need to do HBOT again, but have to wait until I'm clear of cancer, otherwise it can feed it. It depends where you received radiation, and if in the oral mouth, especially the mandible, and above 60Gy, I believe vs. someone who was only radiated in the larynx, neck for example. It's more injury, like extractions is true, that can result in ORN rather than from infections, and ifroot canal can be done it's prefable.

Good luck.
