Paul, I have been using Biotene toothpaste & mouth wash since 2005 when they did radiation on my mouth that left me with no saliva glands & a very sensitive tongue back then but I have regained my saliva glands but my mouth is still very sensitive to different things. The Biotene mouthwash doesn't burn when you use it & they also have Biotene gum & other products that you might find helpful. Your Dentist should be able to help you out there
