TMJ, or Temporomandibular Joint Disorder, means that the hinge connecting the upper and lower jaw isn't working properly. This hinge is one of the most complex joints in the body, responsible for moving the lower jaw forward, backward and side-to-side. Any problem that prevents this complex system of muscles, ligaments, discs and bones from working as it should is called TMJ.
Often, TMJ feels like your jaw is popping or clicking or even "getting stuck" for a moment. The exact cause of this misalignment is often impossible to determine.
Depending on the severity of the TMJ disorder, treatment may include oral appliances, steroid injections, occlusal adjustments, or orthodontic/prosthodontic treatment to improve occlusion. In cases of persistent and serious TMJ problems, surgery may be recommended.
