I have severe jaw pain on my right side and can't completely close my mouth, which makes eating difficult. The pain also travels to my right ear. This has been going on for several months and has gotten progressively worse. I said something to my primary care doctor about it at my last visit. She looked in my mouth, had me open and close and asked me if my dentist ever told me I grind my teeth. I said no, and she really didn't say anything after that. I know I do clench my teeth, but wouldn't the other side hurt also? Can you give me some kind of idea what this might be and what type of doctor I should see about it?
