The jaw joint, or the temporomandibular joint, connects the lower jaw to the skull. It is a ball and socket joint, with a disk between the ball and socket to cushion the joint. Normally, the disk sits right on top of the ball, and moves forward and down with the ball when opening mouth, and also moves up and back with the ball when closing the mouth. Clicking in the jaw joint when opening the mouth often indicates that the disc inside the joint may be partially displaced. The disc cannot be seen on x-rays, and is best visualized on an MRI, or magnetic resonance imaging.
If the jaw joint clicking is not painful and does not affect function, it may not require treatment. However, if pain or dysfunction is associated with the clicking jaw joint, treatment may help relieve the pain and improve function. This is probably why your dentist recommended that you see an oral surgeon.
