Tempero-Mandibular joints (TMJ) – their functions and disorders

Tempero-mandibular joints or TMJ as they are called, are a type of paired joints, one on each side of the face, just in front of the earlobe. These joints are a part of your lower jaw or mandible, connecting it to the skull bone. TMJ is the ones that enable us to open and close our mouth, chew food up and down and towards our sides of the mouth. This joint works like a ball and socket, so it enables multiple free movements of the mandible. The number of movements a joint is able to perform, the weaker is the joint. So they are subjected to a lot of stresses, which can cause discomfort in certain patients. Any vague pain in the face or around the tooth, or pain around the ear while chewing or eating food, or pain on yawning could be symptoms associated with TMJ disorders.

It is best to consult a dentist and checked clearly. He or She would suggest x-rays, clinical tests to assess TMJ pain.
