Hi Andrew,
I did the 20/10 HBOT before, and after, the dental extractions, and inquired about additional HBOT when it was showing early ORN after 3 months, but my Oral Maxillofacial Surgeon said it wouldn't help, it failed twice before, and needed additional surgery/flap to close the socket, and after that too seemed to have failed after several months I was sent to the Chief Oral Maxillofacial Surgeon, who is a known authority with ORN, but he said it was granualization, not showing bone at that point, so I inquired about HBOT to speed healing, and he too said it wouldn't help.
Actually, I was relieved not to do it again. After I did HBOT in 2011, for the same 3rd molar, I had a cancer recurrence about a month after I finished. Plus it really tired me out like radiation did, messed with my vision, balance, increased neuropathy, sinus, and needed a blood transfusion in 2011 midway. Wether or not some of these were related or not just doesn't make me want to do it unless necessary.
So far, so good. Went for my last follow-up visit about two weeks ago, and now on a 3 month follow-up plan. Still can't get dentures though.
