A nightguard looks quite similar to the dental trays used for teeth whitening. They are customized to sit over your teeth and protect them from grinding or clenching. The device is made of plastic and worn while you are sleeping to prevent you from unconsciously grinding your teeth.
Experienced dentists in Plantation, FL, recommend nightguards if you have bruxism issues. Bruxism can cause you to clench or grind your teeth, typically when you are asleep. It mostly happens unconsciously, but for some people, it can happen under stress, when they are awake.
The primary aim of the nightguard is to separate your top, and bottom teeth set so that they do not get damaged from each other due to grinding or clenching.
