The TMJ or Temporomandibular joint is the joint connecting the jaw to the skull. TMD or Temporomandibular Disorder is the dysfunctions of the jaw muscles. Due to its location in front of the ear and at the rear of the mouth, proper function of the TMJ is mainly dependent on the maintenance of healthy teeth.
The etiologic factor causing TMJ pain is mal-occlusion. If untreated, these can lead to further breakdown of the joint and facial structure.
