Thank you all for the suggestions. I will definitely talk to my RO tomorrow. My dentist knows about the radiation starting but he still scheduled me for a cleaning. He seemed pretty confident there wouldn't be any problems, but even though he is a professional I think people who've experienced this would know better. I didn't even think of infection, my main thoughts were about how sensitive my mouth will be. I keep forgetting how vulnerable my mouth is going to be to infections. I just saw a commercial for biotene today and I was going to ask my doctor about it, funny that you recommend it! I've already received my trays, I was fitted last Friday and got them this past Friday. Getting the molds was awful I pretty much spent a minute almost vomiting until the mold came out. Just horrible.

I don't know if it's nerves or what, but it's 2AM and I can't sleep, my radiation starts in 6 hours. Anyone else have sleepless nights?
