Rob,
I had a tooth pulled after radiation, it too got the full radiation dose. I did not have HYPERbaric treatments especially for it but I did have 30 dives about 4 months prior to the extraction. Make however sure that you are dealing with and experienced person! Although things healed up ok, I ended up having a fistula between mouth and sinus cavity which was weird and took several months to close. It would have been so much easier to just put one stitch in. I was contemplating an implant too, but then it was just tooth #2 and therefore not a functional nor a cosmetic issue and in the end it was simply not worth the risk. IF I ever consider an implant (elsewhere) I only would do this with a person that has extensive experience dealing with OC radiation patients.
