If you have jaw pain and suspect you might have TMJ, try this: Carry a small kitchen timer with you and set it to go off at random times throughout the day. When it rings, immediately observe how you are holding your teeth, neck and shoulders. Are you clenching your jaw muscles tightly? The subconscious nervous habits of grinding teeth, clenching muscles tightly or slouching into bad posture – all of which can increase pain-causing tension in the jaw and neck – can be overcome with patience and persistence. Making your subconscious actions conscious helps you to change them.
