A mouthguard is a flexible, plastic material used by athletes such as football players or basketball players. It protects the teeth against impact.
Another kind of mouthguard is used to protect the teeth against clenching and grinding at night. Called a nightguard, this type of mouthguard is made of a harder, plastic material.
