Hi, I'm new here but wanted to add my 2 cents worth. I had a total glossectomy in July 2003 with left and right neck dissection. I have been using the fluoride trays every night for about 30 minutes before bed. I guess all people really are different because they (and the fluoride) don't make me gag so I guess I'm pretty lucky. I haven't tried any of the biotene products but I do brush my teeth with SF 5000 plus toothpaste (by prescription only). So far all is well at the dentists office. Anyway, just wanted to add something to this very helpful website. I plan to post something to the "introduction" section soon so as to introduce myself to all of you and get your input on some questions I've been mulling around in my brain. Thanks! Nancy
