Hello Everyone, Hope all is going well. My questions is, I finished Chemo and Radiation treatments in Nov 2008. BOT & Lymph Nodes on the left side. In August of 2011 I needed 2 teeth removed, I did 30 HBOTs before and 10 more after the extractions, these were ordered by my ENT. I am now in terrible pain and need 5 more teeth removed, my ENT says not till I do more HBOTs. My Oral Surgeon who I need because of limited mouth opening and a well known, respected surgeon from the Cleveland Clinic says NO. He says once you do HBOTs, You are good for life, there is no proof that doing any more will do anything else???? Does anyone have any experience going thru this or can give me some input? Thank You all very much. Randy in Eastern Ohio
