Temporomandibular disorders are problems with the joints, ligaments, tendons, or muscles connecting part of your skull (the temporal bone) to your lower jaw bone (mandible). These used to be called TMJ (temporomandibular joint) disorders.
The temporomandibular joint connects your skull to your lower jaw bone. This joint moves in many ways. It opens and closes and slides backward, forward, and side to side. Chewing creates a large amount of pressure on this joint. A piece of cartilage, called a disk, keeps the skull and the lower jawbone from rubbing against each other.
