TMJ is the abbreviation for Temporal Mandibular Joint. It is the joint directly in front of your ear that is used by your body to open and close your mouth. It is, like most other joints in your body, made up of cartilage, fluid, bones, and muscles.. And just like any other joint in the body any piece to this puzzle can deteriorate, get misplaced, damaged, or have any other number of problems.
If any sort of damage does occur then pain, clicking, popping may result.
If you have had any of the above symptoms the best thing to do
is to see your dentist right away.
He/she needs to determine what is the cause of your TMJ discomfort and
what, if anything, can be done to solve the problem.
