Bruxism is medical term for the clenching and grinding of teeth during sleep (and can sometimes occur while awake).
Bruxism is classified as a sleep disorder as it may be associated with moderate to severe dental damage from the grinding, with subsequent jaw pain, sleep disturbance and daytime tiredness.
Precise causes of Bruxism are unknown, however studies have linked it to factors such as stress, anxiety, alcohol consumption, caffeine, sleep apnea and fatigue.
An attended Level-1 sleep study is the best methos of diagnosing sleep Bruxism. Once diagnosed, A Dentist can often fit a dental device which will minimise the impact of damage to the teeth from the grinding. Jaw alignment exercises may also assist in facial pain.
