Dislocated jaw or tmj---how do you know the difference?

Lock Open/Closed: A dislocated jaw locks open- you can't close your teeth together. With tmj, the disc usually displaces forward causing the jaw to be locked shut- you can't open your mouth. Both can be painful.

Tmj: I would assume you have TMJ disorder. If you ha a dislocated jaw you would not be able to open and close at all with or without pain. See a dentist who can treat tmj. In my opinion the best treatment is functional orthodontics. I treat many TMJ patients like this and have great results. The pain, clicking, and headaches are usually gone after the first day of treatment.

See a specialist: I would like to know who offered you the diagnosis of tmj. Was it your doctor, dentist, chiropractor, ent, physical therapist, tmj/tmd specialist? You should really see a tmj/tmd specialist to proceed from there.

TMD TMJ: TMD and "TMJ" refer to disorders of the jaw joint and associated structures. A dislocated jaw is ONE OF TMJ disorders. See an oral & maxillofacial surgeon for expert advice
