I start 7 weeks of radation for tonsil cancer in 2 weeks. I first went to my regular dentist to get clearance for radiation, but he did not have enough experience with head/neck cancer patients. He did make my flouride trays. I am very glad I saw a specialist who was able to describe what will happen to my teeth (no extractions needed before treatment)and educate me on my ongoing responsibilities. Looks like I'll be using nightly flouride trays forever. One piece I was unclear on was the use of stents. The specialist suggested them (due to my crowns?); however, the oncolgist said because she is using IMRT, stents wouldn't be needed. The tumor was removed (T1N0M0) and does not have appeared to spread, so the radiation to the non-tonsil areas will be limited. Do most people use stents during treatment?
