I have been having some dental pain with one tooth, and have seen both dentist and endodontist. Million dollar tooth already, at some point in the past 40 years had a pin, root canal plus crown... I am wondering if I grind my teeth at night, I know some people have mouth guards. But how did you find out you were doing this? I take a lot of meds that dry me out, and am sure I sleep with my mouth open as in the morning it is cotton..... all that yucky stuff. I kind of thought if my mouth is that dry I can't be doing grinding, but I don't know the answer to that. Thanks if you take time to reply.
