A night mouth guard is a device one wears while sleeping to protect one’s teeth from nighttime grinding (bruxism) and reduces the occurrences of chipped teeth.
The night guard fits over one row of teeth, securing the device in place and keeps your top and bottom row of teeth having direct contact with each other.
You can get yourself a night guard over-the-counter from a drug store. This is the cheapest option, but it works for most people. You can also schedule an appointment with a dentist or orthodontist and purchase one from them. This is the better option, but can be quite costly and some people find that a generic mouth guard already solves their problem.
When looking for a night guard, you have to consider some factors. First, it should fit comfortably. It should also be made of a durable material, yet soft inside one’s mouth (rubber or plastic are great options). If possible, try to find one with a double wall; it will fit tighter and last longer than single wall guards.
