Bruxism is a condition in which one grinds, clenches, or gnashes his teeth. Many people grind or clench their teeth, either by day or night, without being aware of what they are doing. This can be triggered by a dental malocclusion, stress, or worry. This muscular over-activity sometimes gives rise to muscle spasm and headache. Most often, these headaches are classified as tension-type. A dentist often can ease those symptoms by fitting a small appliance to the upper teeth, which is worn during sleep. Medications, physical therapy, biofeedback, and other stress reduction techniques sometimes are utilized.
In recent years, the growing awareness of dental causes of puzzling facial and head pain has enabled many individuals to benefit from appropriate dental treatment.
