The temporomandibular joint (TMJ) is a small but complex joint located in front of the ear where the lower jaw connects to the skull. The joint allows for complex movements essential for chewing, speaking, and facial expressions.
When this joint, or the cushioning cartilage within it, becomes damaged, it can lead to TMJ disorder (TMD). Muscles and ligaments supporting the TMJ also play a role in TMD, a condition that impacts around 1 in 10 people.
