Many healthy people experience sounds — like clicking or popping — without pain in the jaw. These sounds, without pain, are harmless and are not TMJ. People with TMJ have one or more of the following symptoms:
Pain in the jaw joint or chewing muscles.
Pain radiating into the face and neck.
Limited movement or locking of the jaw.
Painful clicking, popping, or grating in the jaw when you open or close your mouth.
A change in the way the upper and lower teeth fit together.
Ringing in the ears.
Ear fullness.
Hearing loss.
