Debbie, it seems that for now, your main questions concern teeth and radiation....very valid concerns, for sure! I suppose that your surgery will be a palatectomy. I had a partial maxillectomy and a partial palatectomy, and I now wear an obturator appliance to close my palate. If you are interested in the details of my experience, search for posts by me, under the name "August." I didn't have radiation or chemo, so I can't help you there. Good luck!
