What is the primary purpose of a mouthguard?

The primary purpose of a mouthguard is to protect teeth from injury during sports. Mouthguards are designed to absorb the shock from impacts that can occur during physical activities, especially contact sports where the risk of dental injuries is higher. They create a protective barrier that mitigates the force on the teeth, gums, and jaw, preventing chips, fractures, and avulsions of teeth, as well as soft tissue injuries in the mouth.

While other options cater to various dental needs—such as aligning teeth, promoting oral hygiene, or cosmetic improvements—these functions are not the main role of a mouthguard. The specific design and materials used in mouthguards prioritize impact resistance and safety, underscoring their essential role in injury prevention during sports.
