Temporal Mandibular Joint Syndrome

Ok, thankyou for that kitty

Dh says heat is better then he should be able to open and close it

Google says heat or ice kitty
It only came on today, we'll give it a few days and if no improvement make a dental appointment. It's not giving him pain unless he tries to eat.

I had it a few years ago. I rubbed Voltarol in the area at night [you shouldn't have Voltarol on your skin if it's exposed to sunlight]. It did go away after a while but I was scared to eat for a long time afterwards and am very careful when I yawn. It started when I was trying to stop smoking and was chewing a lot of gum; one day I was chewing and I felt as if I'd dislocated my jaw, which was very scary at the time.

Will he go to the dentist for a proper diagnosis? The one I sleep with says use warmth not cold and gently exercise it.

It is often associated with clenching and grinding of the teeth. If it is TMJ the dentist might prescribe a special bite guard
