The temporomandibular joint or TMJ is arguably the most complex joint in the body.
These two joints and their respective muscles work together and allow you to talk, swallow, and chew. There is a cartilage disc in each joint that acts as a cushioned pad to help the jaw open widely, rotate, and glide through its movements.
Any problem that keeps this system of muscles, nerves, tendons, ligaments, bones, connective tissue, and teeth from working together properly can cause pain or discomfort.
