Temporomandibular joint (TMJ) disorder

Temporomandibular joint (TMJ) disorder

The TMJ is the joint that allows interaction between the temporal bone of the skull and the lower jawbone. Problems can occur if the jaw pivots when opening or closing or during a lateral movement. This affects the TMJ and the chewing muscles and causes temporomandibular joint disorder (TMJD or TMD).


  • Earache without infection
  • Pain that is more intense in the morning than in the afternoon
  • Pain in the jaw when chewing, biting or yawning
  • Clicking sound when opening and closing the mouth
  • Difficulty opening and closing the mouth
  • Locking or stiffening of the jaw when speaking, yawning or eating
  • Teeth sensitivity with no observed dental problem 


A lack of harmony between your bite and the ideal position of your jaw is the major cause of TMD. Physical trauma is another possible cause. Stress and clenching (or grinding) are only aggravating factors.
