Ray1971, Thanks for all the information. When you used your fluoride trays, how long did you leave the trays in before you took them out? I usually use mine before bedtime. I saw my oncologist today. He said I would have 35 treatments, and I did ask him about the chemo and he said he was not sure yet as he wanted to see the current ct scans and talk with another Dr. before making the final decision. I had to have some dental work done and due to that and one of my Dr's. holding things up for me until I kept calling them back to get things done quicker. I had my tonsil removed the first week in June, 2008, and am just getting to this point for radiation so I have been very worried about the length of time this has taken. I have some very kind Dr's. however and they are very nice to me. Thanks, Angel
