TMJ Causes

TMJ disorder rarely stems from a single cause. It typically develops when multiple physical, functional, and lifestyle factors combine to place excessive strain on the jaw joints and surrounding muscles. Understanding all contributing factors is essential for effective, lasting treatment.
Common causes and contributing factors include:
• Jaw misalignment or an uneven bite
• Chronic teeth clenching or grinding (bruxism), often during sleep
• Overuse or imbalance of the jaw muscles
• Stress and tension held in the jaw and face
• Trauma or injury to the jaw, head, or neck
• Poor head and neck posture that alters jaw position
• Poor quality sleep
• Sleep disordered breathing
