I had to have mine pulled before rads and chemo started. They can decay and cause infection. Get them out 1st because you will have enough to deal with. I had rads at chemo at the same time.

Since posting this. UPMC, Pittsburgh, Oct 2011 until Jan. I averaged about 2 to 3 surgeries a week there. w Can't have jaw made as bone is deteroriating steaily that is left in jaw. Mersa is to blame. Feeding tube . Had trach for 4mos. Got it out April.
