When a child begins to participate in organized sports mouth injuries can occur. A properly fitted mouth guard is important in helping protect your child’s teeth and smile and should be used when engaging in any activity where there could be trauma to the face or mouth. Mouth guards help prevent broken teeth and injuries to the lips, tongue, face or jaw. A properly fitted mouth guard will stay in place while your child is wearing it. Ask your pediatric dentist about custom and store-bought mouth protectors.
