What can i do about my jaw locking up besides ice?

Jaw locking up: If your jaw is locking closed, it generally means that the disc in the jaw joint may be displaced. If your jaw is locking open, that means that the jaw is itself becoming dislocated, which is much less common. For a closed lock that fails to respond to simple measures, it has been shown through many studies that the most effective treatment is TMJ arthrocentesis or arthroscopy, to unlock the jaw.

See your Dentist: Important to determine cause of joint dysfunction that has caused disc displacement. Depending on cause you may need thermal therapy, medications, occlusal orthotic, orthodontic tooth movement, occlusal adjustment, joint or jaw surgery, or other treatment modalities. Start with your Dentist.
