Bruxism is teeth grinding and/or clenching at nighttime. A number of children and adults have this condition, which is frequently brought on by stress. Other causes include misaligned teeth and ADHD. Symptoms typically include headaches, facial pain, tenderness and/or clicking over the TMJ (jaw joint) and ear pain. Examination usually shows worn teeth (see picture) and there is frequently tenderness over the TMJ. Treatment includes a sports-type mouth piece, either over-the-counter or custom made by a dentist, and special exercises. Occasionally, muscle relaxants are used to decrease clenching and improve sleep…..Richard R Samuel, MD Family Practice and Urgent Care Hayden, ID USA
