A night guard is meant to protect the teeth from clenching and grinding during sleep. It is worn every night or every time the person sleeps, so it is fabricated using a material that is not as thick but strong enough to serve its function.
A sport mouth guard is an appliance that is prescribed to an athlete to protect his teeth from being damaged from a physical blow to the face or an accident. A sport mouthguard is usually made with a thicker material and given its purpose, it is made to extend to cover the entire jaw, even the gum issue so that the entire mouth can be protected.
When an athlete has his mouth guards made, he can make a decision to incorporate his team colors with the appliance or even the team logo or sign. Sports guards may be fabricated so that it is part of the team uniform. There are different dyes that may be added to the acrylic material, so that some color may be incorporated.
Both a night guard and a sports guards are meant to protect teeth, but they protect your teeth in different ways. A nightguard functions by protecting the teeth surfaces from being worn down from constant grinding and clenching. A sport mouth guard is primarily worn to protect the teeth and mouth in case of sudden, hard impact. As a result, while a night guard may be made from durable hard acrylic plastic to withstand grinding over a long period of time, a sport mouthguard is usually made from a softer material that can absorb the force of sudden impact. And while a dental night guard only needs to cover the occlusal surface of your teeth, a sport mouth guard should cover your teeth including your gums.
