Temporomandibular Joint (TMJ) Disorder
The temporomandibular joint connects the jawbone to the skull. Up to 10 million people suffer from painful temporomandibular joint disorder (TMD), according to the National Institute of Dental and Craniofacial Research. Symptoms include pain in the face and neck, locked jaw or limited jaw movement, painful clicking when moving the mouth, dizziness, difficulty chewing or swallowing and a change in the way the teeth fit together. TMD is about four times more common in women than men.
