Since then I have had various problems including a burning tongue and the same problem with the roof of my mouth. (Also have a very
dry mouth, which I never had before the root canal). Went back to the Endodontist and my family dentist. I was told to go to my family doctor, which I did today. I received no help from any of them. You can't see anything in my mouth, but it burns so bad (tongue and roof of mouth). I have been using Biotene, but it only works for a brief period of time.
