Parafunctional oral habits are habitual unconscious use of the jaw system in functions other than normal (e.g. chewing, speaking and swallowing).
Pain of temporomandibular (TM) muscles and joints is sometimes a product of over work and/or trauma to the jaw. We cannot completely rest these muscles and joints because we use them for chewing, speaking and swallowing. However, we can limit extra use by reducing parafunctional habits.
Examples of parafunctional habits include chewing gum, biting fingernails, pursing lips, daytime teeth clenching and grinding, smoking tobacco products, biting pens/pencils, pushing jaw forward and pushing tongue against teeth/roof of mouth.
Our goal is to consciously teach the unconscious mind not to perform parafunctional habits.
Practice mouth relaxed (MR) position:Position teeth slightly apart with lips relaxed (usually apart) and tongue resting quietly in the floor of the mouth (not pushing against teeth/roof of the mouth).
Practice frequently, so this position feels normal (I minute for 6 times/day).
