Your mandible can move and your joints work with a myriad of muscles in your jaw.
Bones interact with the joint. They’re separated by a small, shock-absorbing disk and are covered by cartilage. These bones ensure jaw movements are smooth and healthy.
When TMD sufferers first experience symptoms, the parts connected to the joint are first damaged.
This can be caused by a number of different factors. For example, the disk can erode or get out of alignment. Many people develop TMD if their joints are damaged due to injury.
Other ailments, such as arthritis, leave you at-risk for developing TMD.
