How to treat lockjaw?

See below: A 'locking' jaw is usually caused by the disc in the jaw joint becoming malpositioned. This can be caused by clenching or bruxism (grinding the teeth at night). When the jaw 'locks', it can be in an open position or a closed position. This is a temporomandibular joint disorder (tmj). This can be treated by a dentist (with oral appliances) who has the proper training and experience.

Acute or Chronic?: "lock jaw" is a condition where the TMJ cartilage disc becomes displaced either forward (closed lock) or backward (open lock). Acute problems can be treated with warm/cold/warm/cold 5mins each, and nsaid's. Chronic conditions often require splint therapy, physical therapy, nsaid's and muscle relaxers occasionally. See a dentist who is knowledgable in TMJ treatment.

See your dentist: If you are experiencing a limited opening this could be indication of internal joint issues that can get worse with time. I personally have treated patients with a maximum of 10mm opening with severe pain. Don't let it get that bad. Schedule an appointment with your dentist or a TMJ specialist.

Oral surgeon: If your jaw is acutely locked (limited oral opening), it can be "unlocked" by jaw manipulation. ASAP. If you go to a traditional "TMJ" doc, he/she will likely treat you with a splint etc, creating a chronic problem

See OFP specialist: Orofacial Pain provides diagnosis and management of pain in the face, TMJ disorders, locking jaw as well as, associated headaches and neck pain. They are the experts in this field. Good luck.
