How does a Nightguard work?

To know about night mouth guard blog, a nightguard is a plastic piece that looks like a retainer and can be hard or soft. It covers the biting surfaces and can be worn on either the top or bottom set of teeth. Since everyone’s teeth are different, a nightguard is made specifically for each person by shaping it to fit your teeth without being too tight or bulky. It has a lot of different names, but dentists all mean the same thing when they talk about a mouthguard, occlusal guard, bite splint, dental guard, or nocturnal bite plate.

Why it’s Important to Choose the Right Nightguard

Prevent Plaque Development

Even though the names are similar, you shouldn’t confuse a sports mouthguard with one that keeps you from grinding or clenching your teeth. A mouthguard for sports will hurt more than help. It goes over the teeth and gums to protect them from being hit by something hard. If you wear a sports mouth guard at night, it traps bacteria on the gums while you sleep because saliva can’t reach the gums.

Saliva neutralizes acids that can cause cavities and washes away food particles, which stops plaque from building up. So, the best way to find a nightguard that won’t hurt your teeth is to talk to a professional in oral hygiene. It’s important to remember that some nightguards have holes that let your saliva get to your teeth. So, a dentist will help you choose the right design based on how good your teeth are.

Don’t change the way you bite.

A nightguard is made to fit your teeth and bite. Because they are soft and made of a thicker rubbery material, sports mouthguards are not made to fit your bite. Softer things will make you chew while you sleep because your brain thinks they are food. After a while, the effect would show up when your bite changes.

Hard nightguards are the most durable because they are made of a firm material.
