Another commonly occurring parafunctional habit is bruxism, or grinding of the teeth. Moving the jaws back and forth or sideways while sleeping has the detrimental effect of wearing down your teeth.
It also places stress on the facial muscles and can be associated with frequently occurring headaches, muscle aches, ear pain, and other symptoms of temporomandibular joint disease (aka “TMJ”). A night guard can help, as it creates a barrier that will keep you from damaging your teeth and acts as a cushion that will help reduce the stress and relax the muscles and the joint.
