You hear about it. You think about it. You try to prevent it, but it keeps on happening. When you find yourself stressed, it can manifest in your body in all sorts of ways. Some people get a stomach ache, some develop heartburn, and others perspire. Many people, however, clench their jaws. While it might seem harmless at the time, overusing your jaw can damage your temporomandibular joint (TMJ).
Your temporomandibular joint is the sliding hinge that connects your skull and jawbone. When this feels sore or painful over long periods of time, you might have a TMJ disorder (TMD).
