I had several extractions before radiation in 2011, but not after. I was supposed to have one extracted, and did 30 HBOT in 2011 for an impacted, abscessed tooth, but was hospitalized for a transfusion, and a recurrence one after the other, so I never did have it extracted. I currently need all my teeth extracted, and was waiting for cancer clearance, which I received today, and my RO said for sure I need to have HBOT, but I had much more radiation than most did, and recently finished one treatment in January.

If they can do root canal instead, it may better, I was told by a dentist. I didn't need HBOT for any root canal after radiation.
