For more than half a century, the American Dental Association has recommended the use of a properly-fitted mouthguard to reduce the risk of oral injury while participating in sports. Although mouthguards do not guarantee someone will not sustain an oral injury, athletes become 60 times more likely to get hurt when not wearing one. Hard hits and flying projectiles can all translate into a nightmare for the teeth and jaw. A custom-fitted mouthguard, worn over the top teeth, protects the teeth from the surrounding soft tissue, absorbs shock, and stabilizes the jaw during a hit. Consider many risks associated with not wearing a mouth guard, including broken or lost teeth, jaw injuries, lacerated lips and cheeks, and damage to orthodontic appliances.
