Bruxism is a dental term that is characterized by involuntary jaw movements such as teeth clenching and grinding. These movements usually occur during sleep at night, but some people may also clench their teeth unconsciously during the day.
Bruxism can cause pain, fatigue, and tension in the jaw and facial muscles. It can also lead to symptoms such as tooth wear, fracture, or cracks, as well as headaches, neck pain, and ear pain.
Although the exact cause of bruxism is not known, it is believed to be influenced by factors such as stress, anxiety, sleep disorders, misalignment of teeth, or jaw structure disorders. Bruxism is usually diagnosed and treated by a dentist. Treatments may include protective coatings for the teeth, a specially designed mouthguard or night guard, stress management techniques, and if necessary, painkillers or muscle relaxants.
