Can a food allergy cause bruxism?

Question

I have clenched my teeth for over 5 years now and it is very painful. I have a nightguard and am on a mild antidepressent and still have problems.

Answer 1

Not that I know of. Stress can bring about clenching. It's a good idea to continue wearing your night guard since it helps prevent further damage to your teeth. I would suggest some relaxation technique prior to bedtime to relief any tension you may have built up during the day.
