Good question!: Tmj is not one but many conditions known together as temporomandibular disorders. They range from problems with the muscles and the bite to internal derangements of the joint itself. Inside the joint there is a disc which can become displaced, causing painful clicking or popping, locking of the joint, and eventually, a very common kind of arthritis, degenerative joint disease, or osteoarthritis.
Dr. Robert Eckelson

Complex: The jaw joint is a very different one from all others. It has a disk which separates the upper jaw bone from the lower jaw bone in all movements of the jaw. It must work in tandem with all the teeth, the other side of the jaw and a myriad of muscles and tendons. Any screwup of any of these parts can cause a tmd.
Dr. Louis Gallia

TMD: TMD (temporomandibular joint disorders) refer to pathological problems within and surrounding the joint. Some derangement of structures. Many types. See an oral surgeon for expert advice.
Dr. John Van der Werff

Seeing a tmj expert is key.. not all oral surgeons know the tmj as well as Dr Gallia..

Probably not: Since i'm not there to hear them and are not described i assume it is a crunchy scrapy sound. This sound is called crepitus and is very common with arthritis. It is a harmless noise and has no correlation with disease (arthritis) activity or stage.
