Mouth guards, Also called mouth protectors, help cushion a blow to the face, minimizing the risk of broken teeth and are a great way to protect the soft tissues of your tongue, lips, and cheek lining. Knowing how to prevent injuries like these is especially important if you participate in organized sports or other recreational activities.
Studies show that athletes are 60 times more likely to suffer harm to the teeth if they're not wearing a mouth guard. While collision and contact sports, such as boxing, are higher-risk sports for the mouth, you can experience a dental injury in non-contact activities too, such as gymnastics and skating.
