I'm not sure if others here have had the wisdom teeth done, but I know some have had extractions - what your doing is right - the HBO - hopefully this will help you heal. I too still have my wisdom teeth and am hoping never to have to have them removed. Hopefully things will go well. The best thing about it is the fact that you are young and will likely heal quickly. The scary thing is you are still so close to rads having finished. But it sounds like you are doing well, so that is definitely in your favor. The HBO should help with tissue perfusn and promote healing post extraction. Best of luck and I'm sure you'll come out ok. Hugs! And congrats on the clear scan and getting on with life.
