Hi Johnnie, Sorry to hear of your troubles.
I'm a long term survivor and don't visit OCF very often and have not posted in years (that's good news!)

I had successful rounds of HBO to treat recurring infections in mandible.
Initially (2004) the HBO was to prep for surgery and my doctor was not sure HBO would help, but decided to do it as a precaution/prep measure before surgery (proposed bone graft to mandible).
To the doctor's surprise the HBO worked so well that it completely eliminated the need for surgery!!!
About a year and a half after that I did another round of HBO.

So, I'm a case where HBO was successful without surgery.

I think for you it may depend on what the problem with the molar/wisdom tooth is. I am not a doctor or medical professional so this is just my impression & understanding, but if the issue is infection & healing then HBO is more likely an option, but if the problem is the physical impact of teeth & bone then HBO may not address the issue.
