Imagine waking up to discover you had ground your teeth while sleeping to the extent of hurting yourself. This is called bruxism. As strange as it may look to many people, bruxism is a common occurrence. You may also grind your teeth unconsciously while you are awake. However, it is more common during sleep than in the daytime, and nocturnal bruxism is among the most common sleep disorder. The conventional solution to bruxism is for the dentist to recommend a nightguard. This will keep your jaws apart and prevent them from grinding against themselves.
