Sleep bruxism (teeth grinding) is a common symptom that people suffer from. It is characterized by the repeated clenching and grinding of one’s teeth. While it’s usually prominent during sleeping hours, a lot of people do it subconsciously when they are awake. Bruxism can cause an accelerated loss of bone and wears down the tooth structure. A nightguard is the most effective and least intrusive treatment for the majority of patients. It works to keep the chewing muscles relaxed and prevents teeth from coming in contact with each other while you sleep.
