Most people who grind their teeth are not aware of their condition. In fact, many people will insist that they don’t do so. The dental term for the grinding and clenching of teeth is called bruxism.
“Bruxism....” It even sounds grating. And, believe me, it literally is. The word itself is taken from the Greek “brugmos,” which means the “gnashing of teeth.” Many people are surprised to learn that it is considered to be one of the most common sleep disorders. If you have it, you should take it lightly. While a night guard does not "cure" bruxism, it can protect your teeth and jaw from significant damage.
