Signs and symptoms of TMJ disorders may include: 
Pain or tenderness of your jaw
Pain in one or both of the temporomandibular joints
Aching pain in and around your ear
Difficulty chewing or pain while chewing
Aching facial pain
Locking of the joint, making it difficult to open or close your mouth
 TMJ disorders can also cause a clicking sound or grating sensation when you open your mouth or chew. But if there's no pain or limitation of movement associated with your jaw clicking, you probably don't need treatment for a TMJ disorder.
