People wear nightguards because they grind their teeth or clench their jaws at night. The act of grinding and clenching often occurs when you’re sleeping or under stress.
Nightguards don’t stop you from clenching or grinding, but they serve as a cushion. During grinding the guard wears down instead of your teeth. Nightguards also give your jaw a rest while you sleep. Moreover, they can help you and your partner sleep better.
