Hi, My husband had nasopharynx cancer and is eleven months post radiation. All of his teeth have decayed from radiation and he needed to have them all pulled out two weeks ago. He had 20 hyperbaric treatments before surgery and 10 treatments after. Implants have been mentioned but oral surgeon and radiation oncologist say not right now. Try dentures first, implants can always come later. There is a risk of infection with implants which I think my husband is not willing to take at this time.. He will go next week to talk about treatment plan and get fitted for dentures. HBO treatments seem to do the job of helping the gums heal. He had no trouble healing. Eileen
