Please check first
If jaw pain starts from a particular tooth, or that tooth hurts when you chew, the cause may be the tooth itself rather than the jaw joint, so it needs to be checked at a dental clinic first.
Rarely, if after the age of 50 your jaw hurts when chewing and tires easily, and this appears together with headache or changes in vision, it may be temporal arteritis. In that case prompt care is needed to protect your sight.
