Hi Guys, I have a question about HBO treatment. I have a tooth that has had two root canals done on it and it doesn't seem to be healing properly,etc. HBO was mentioned to me by my oral surgeon, in fact, he told me to ask the dentist doing the root canal to try and save the tooth if at all possible. Is the HBO necessary after radiation treatment in all cases? And is it only when you have teeth pulled? I still don't quite understand it. Thanks so much!!!

Diagnosed May 2002 with Stage IV tongue cancer, two lymph nodes positive. Surgery to remove 1/2 tongue, neck dissection, 35 radiation treatments. 11/2007, diagnosed with cancer of soft palate, surgery 12/14/07, jaw split. 3/24/10, cancer on tongue behind flap, need petscan, surgery scheduled 4/16/10
