I was treated for throat cancer in 2002 My teeth have been getting decay .I am told know i need teeth extracated. I have been told much of my jaw was not irradiated so i can under go fillings and root canals in the anterior mouth.My question is has any one had teeth extracated after radation treatment. And did they have to have hyperbaric oxygen befor and after the removel of teeth. And also dose the fact that its been 6 years since i was treated healed the efects of radation . thanks honda
