Basic informations
Bruxism or teeth grinding is caused by repetitive and uncontrolled masseter muscle contractions.
Most people clench their jaw or grind their teeth from time to time, with no harmful effects. However, if bruxism persists, for example when occurring during sleep, it can cause permanent changes in the mandible, jaw and mouth, leading to adverse health effects. As such, it is not only an aesthetic issue but also a medical problem. For this reason, regardless of bruxism occurrence, hypertrophy of the masseter muscle is currently a common aesthetic indication for botulinum toxin treatment.
