Overview. 1  A slipped disc in your jaw can cause painful temporomandibular joint (TMJ)-related problems, including a âpoppingâ noise that originates inside the jaw joint. 2  Friction is a massage exercise. 3  The jaw stretching exercise may relieve tension in tight jaw muscles forced out of position.
Jaw Locking (Definition) Jaw locking is when the temporo-mandibular joint, aka: the TMJ (everyone has two) gets stuck out of position. Usually because one opens so wide that part of the joint on one's jaw (the condyle) gets stuck in front of the cartilage in the joint (disc) or bone in front of the joint's pivot point (the articular eminence). This is a highly complex and critical joint; if you have problems, consult a professional right away.
