This type pain is often related to muscle tension and fatigue involving the muscles of mastication (used for chewing food and talking). Myofascial pain syndrome is usually a chronic condition resulting from teeth grinding, teeth clenching, and chronic muscle overuse. By treating the areas of muscle pain (triggers points) with anti-inflammatory medications, muscle relaxants, dietary changes, reducing parafunctional habits, botulinum toxin, etc... many patients find adequate relief of his or her symptoms.
