What is the primary function of a mouthguard?

1. To enhance breathing

2. To prevent tooth injuries

3. To improve visibility

4. To prevent jaw fractures

The correct answer is: To prevent tooth injuries

The primary function of a mouthguard is to prevent tooth injuries. Mouthguards are designed to absorb and distribute the forces applied to the teeth during contact sports or activities where there is a risk of impact to the mouth. They create a protective barrier that reduces the likelihood of traumatic dental injuries, such as fractures, avulsions, and other damage to the teeth, gums, and surrounding tissues. While mouthguards can provide some degree of shock absorption that may help protect the jaw, their primary purpose is to safeguard the dental arch. They do not significantly enhance breathing or improve visibility, which are crucial aspects in sport performance but are not the primary functions of a mouthguard. Thus, their role is essential in protecting athletes' oral health, making them a vital piece of protective equipment during high-risk sports.
