Hi Marcia
I had a tooth extraction (#2). My HBO treatments (30) were about half a year prior to that "procedure" and no additional HBO's were considered (and necessary). Mind you this was not a wisdom tooth. If I had to do this over again I would go to a person who is experienced to work with irradiated tissue because a simple stitch would have made things simpler. I echo Brian's sentiment re 100%, If all goes well then, in effect, it is close enough to 100%.
