TMJ or TMD involves the temporomandibular (TM) joints, which are located on each side of your head. These joints work with your muscles, ligaments, discs and bones, enabling you to speak, chew and yawn.

Temporomandibular disorders (TMD) occur when your TMs aren’t working properly.

Problems with your TM joints can be attributed to:

  • Grinding or clenching your teeth
  • Stress, if it provokes you to tighten your facial muscles or jaw
  • Dislocating the soft cushion or disc between the ball and socket
  • Osteoarthritis or rheumatoid arthritis in the TM joints
  • Injury to your jaw, head or neck
