Recently I was doing research for a post on Pain in the ear due to swelling and came across the reason for cracking sound, which I would like to publish in this post. It is nothing major, so no need to worry about the cracking sound. It is called as the TMJ Syndrome ( Temporomandibular Syndrome) termed as a disorder which affects the joint of jaws. You can treat it with a moist heat or cold massage around the jaw. If the sound keeps on bugging you and is painful at time, it would be appropriate decision to see your doctor right away.
Personally I have done nothing for my two time suffering of the jaw cracking but next time it happens I would definitely be seeing a doctor.
