Hello Mark. I have arthritis in my jaw but have not been seen or treated by a doctor. My jaw always clicks and is usually worse in the mornings (possibly grinding my teeth when I sleep). Today my jaw is very painful on the right side and it is getting worse as the day goes on. My bite has suddenly changed this evening and won’t go back. Any ideas what this could be and how to fix it? Or where to start with getting treated? Thank you.
