If "snap," "crackle" and "pop" aren't coming from your cereal, it may be from your temporomandibular joint (TMJ).
TMJ complications affect over 10 million people, according to the National Institute of Craniofacial Research (NICR), and it's more of an issue for women than men.
Although it may be alarming, you can effectively determine if your clicking jaw is just a temporary annoyance or a sign of a more advanced temporomandibular joint disorder (TMD).
The temporomandibular joint can move side to side, as well as backward and forward, making it one of the most complex joints in your body.

Connecting your lower jaw to the temporal bones at the side of your head, according to the Merck Manual, the joint allows you the range of motion needed to speak, yawn and chew food.
Facial muscles attached to this joint control these movements, while a soft cartilage disc within the joint socket absorbs massive amounts of pressure so no single motion does any damage.
