Temporo-mandibular joint

The temporomandibular joint (TMJ) is a sliding and pivoting joint that moves the lower jaw toward the skull.

Problems can occur when the jaw rotates during opening, closing or lateral movement. This affects the temporomandibular joint and the masticatory muscles and causes a dysfunction of the jaw called Temporomandibular Dysfunction Syndrome (TMD).

Les symptômes

  • Earache without infection;
  • Pain in the jaw more intense in the morning than in the late afternoon;
  • Jaw pain when chewing, biting or yawning;
  • Slamming when opening and closing the mouth;
  • Difficulty opening and closing the mouth;
  • Locking or stiffening of the jaw while speaking, yawning or eating;
  • Sensitivity of the teeth with no dental problems observed.

The causes

Most experts believe that certain mental or physical tasks, such as strenuous exertion or stressful situations, cause or aggravate TMD. This disorder is essentially caused by muscular overexertion, particularly due to clenching and grinding of the teeth (bruxism). Consult us to obtain a proper diagnosis. Our experienced team will give you sound advice that applies to your situation.
