Sleep bruxism is characterized by clenching or grinding your teeth during sleep. It is considered a sleep-related movement disorder and is often associated with other sleep issues like snoring and sleep apnea. Many individuals are unaware they have sleep bruxism until a bed partner notices the grinding sounds or dental problems arise.
