I’m sorry to say but I’m 18 years out from initial diagnosis. I used to have beautiful teeth. I recall meeting my radiation oncologist for the first time. He said,”You have such beautiful teeth.” Then I learned from another cancer patient that she lost all her teeth. I knew then that was to be my fate. Unfortunately it happens and the teeth decay, as did mine. I went through hyperbaric oxygen treatments and had them all removed. They were chipping and falling apart. It was horrible but I did what I had to. It prevented Osteoradionecrosis, and for that I’m grateful. I don’t believe there is any way to prevent this. I do believe that the degeneration of the jaw can be prevented. There is hope. The face and jaw don’t need to fall apart.
