TMJ
Temporomandibular disorders can have many different signs and symptoms that range in severity. Some patients may experience symptoms without any apparent loss of function.
How the Jaw Joints and Muscles Work
The joints and muscles on each side of your jaw help open and close the mouth. These joints move in many different directions. They allow you to chew, talk, and swallow. The two temporomandibular joints are among the most complex joints in the body. They work together in a delicate balance with muscles, ligaments, cartilage and your jaw bones. When a problem prevents these parts from working together properly, pain may result.
TMD
Several conditions may be associated with TMD. This often makes it difficult to pinpoint the cause of a particular case of TMD.
