Short Description
A hinge-like joint connecting the jawbone to the skull, allowing movement for chewing, speaking, and facial expressions.
Long Description
The temporomandibular joint (TMJ) is the joint that connects the lower jaw (mandible) to the skull, located in front of each ear. It functions as a hinge, enabling essential movements such as chewing, speaking, and yawning. The joint consists of muscles, ligaments, and a disc that cushions movements.
A properly functioning TMJ allows smooth jaw motion, but injuries, misalignment, arthritis, or excessive stress (such as grinding or clenching) can cause dysfunction. Issues with the TMJ may lead to pain, clicking sounds, or difficulty opening and closing the mouth.
Maintaining a healthy TMJ involves avoiding excessive jaw strain, managing stress, and practicing good posture. If pain or discomfort develops, dentists may recommend exercises, oral appliances, or other treatments to improve joint function and relieve symptoms.
