Thank you Ambra, and for taking the time to write even with your own troubles, surgey, and hope you feel better. Waldeau, I used all the Biotene products, but was not given prescription fluoride, dental trays by a local dentist with my radiation in 2011, I should have known better, maybe there are other contributng factors, but I need all my teeth extracted now, three years after radiation to the mouth, plus having to do HBOT again, but I'll prefer that over a recurrence, if only I can choose so.
