The old fashioned method of treating bruxism is to cover the teeth with a night guard to protect them from strong vertical forces caused by grinding, which causes teeth to crack, break, and over decades slowly wear away to stubs. Bruxism is the medical term for unconscious teeth clenching and grinding while awake or asleep, which can lead to physical painful and severe dental problems. Though there are a lot more that doctor should take under consideration about bruxism, such as stress, depression, anxiety. The best natural treatments may include a combination of cognitive behavior therapy and the use of a mouth guard. Teeth should be repaired if it is needed.
