Joint pain or TMD (Temporomandibular joint dysfunction) and Facial pain can become a pain that you learn to live with as a day-to-day occurrence. It most often presents as a chronic pain but can demonstrate with an occasional acute flare-up. Muscles and the neuro-muscular relationship to the teeth are often the primary reason for this debilitating pain. Obtaining muscular physiologic rest is the beginning treatment for resolving these symptoms.
