Teeth grinding (bruxism) is the unconscious gnashing, grinding, or
clenching of the teeth. It usually occurs during sleep. This process can grind
away parts of the teeth, leaving flattened, worn-down biting edges; fractured
enamel; and painful or loose teeth.
Although the exact cause of bruxism is not always known, it may be
Emotional stress, fatigue, or sleep
An abnormal bite or crooked or missing
Alcohol or drug abuse.
Talk to your dentist if grinding is causing injury to your teeth.
Your dentist will determine which treatment is right for you. A mouth guard may
be recommended to help protect your teeth from further damage.
