Cracky jaw: Sounds like you might be developing TMJ syndrome on that one side. The jaw is a sliding hinge type of joint - with a small layer of cartilage in the joint - we think this starts to wear causing the sounds and later pain. It won't deform the jaw but can lead to pain later. Try to avoid the clinching activity.

Jaw joint noises: Jaw joint noises are very common and seen in at least 25% of the normal population. If there is no pain or limited function of the jaw, the noises by themselves are generally of no concern. However, if there is pain or limited oral opening, it may indicate a form of arthritis. The "cracky" noise you hear may be crepitus, a grating or grinding noise that commonly accompanies arthritis of the joint.

TMJ : Many times this is a jaw disc displacement problem with jaw joint noises. You might be having to displace the joint in the morning to get your teeth back together. So you wake with disc in a more normal position. If you get headaches and have limited opening after biting hard you may get rid of the noise but be putting the jaw in a displaced position. See a TMJ dentist to get it diagnosed.

Be worried: Clenching and a cracking jaw are a bad combination. I would recommend seeing a TMJ specialist for advice.
