A mouthguard should be a top priority on your child's list of sports equipment. Athletic mouth protectors, or mouthguards, are made of soft plastic and fit comfortably to the shape of the upper teeth. They protect a child's teeth, lips, cheeks and gums from sports-related injuries. Any mouthguard works better than no mouthguard, but a custom-fitted mouthguard fitted by our pediatric dentists is your child's best protection against sports-related injuries.
