The temporomandibular joint (TMJ) is the most active joint in the body, opening and closing up to 2,000 times per day to accommodate chewing, speaking, breathing, swallowing, yawning, and snoring.
Temporomandibular joint (TMJ) disorders may be the result of dysfunction in the jaw, cervical spine, or tooth alignment. Approximately 70% of patients with TMJ issues also have cervical spine dysfunction.
