Question: What is TMJ?

Answer: The temporomandibular joint, also known as TMJ, is the ball and socket joint that connects the lower jaw to the bone on each side of the head. The temporomandibular joint is stabilized by muscles that make it possible to open and close the mouth. The pain, discomfort or tenderness in or around these joints are referred to as TMJ disorders.

According to the National Institute of Dental and Craniofacial Research, TMJ disorders are more common in women than men and over 10 million people are affected by TMJ disorders.
