Many people are afflicted with bruxism, or teeth grinding. Some people may do this consciously during the day, but it is a larger problem at night while you are asleep. Grinding your teeth can damage enamel, wear down teeth, cause jaw pain, or irritate your gums. The noise from teeth grinding can also disturb your spouse's sleep if loud enough.
If you grind your teeth you should consider a night guard. The night guard, which is very similar to a mouth guard worn by athletes, provides a barrier between your top and bottom teeth while you sleep. All night guards are custom fitted for comfort and to allow for proper breathing. Your dentist will take an impression of your teeth and have the night guard created by a dental lab. Night guards are very durable and in many cases can be used for years.
