It does not stop the habit, but it allows your jaw to rest properly. This helps muscles relax, resulting in improved sleep patterns, too. Mouthguards also help you by preventing costly tooth damage. The habit of grinding and clenching can cause chipped teeth, damaged fillings, and excessive wear.There are two types of mouthguards:

An athletic/soft mouthguard

An athletic/soft mouthguard is used during the day time for sports and exercise or daily stressful activities.

Nightguard

A night guard is usually a harder material. You put it on to go to sleep so you don’t damage your teeth when you grind them while you sleep. You can cause fracture lines, and enamel wear by doing this too much. The mouthguard prevents this.
