Contact and ball sports put front teeth at real risk, and a knocked-out tooth is expensive and often permanent. A custom-fitted mouthguard absorbs the impact far better than a bulky off-the-shelf version and stays comfortably in place.
Mouthguards also help people who grind their teeth at night, cushioning the bite and easing jaw strain. Whether for the field or for sleep, a guard made to fit your mouth protects teeth that are hard and costly to replace.
