Fractured facial bones are common amongst cricketers, boxers and hockey players, where the player is either hit by an accelerating ball or racquet and stress fractures from repetitive blunt force in boxing. Batting helmets and face guards are used to protect against such injury. The mouth, lips, teeth, gums, jaws, tongue and cheek are vulnerable to blows that can cause tears, fractures and even concussion, depending on the impact. Mouth protection is a requirement for sports like boxing, hockey, rugby and squash, where collision and trauma may be high. These guards should fit the mouth appropriately, be durable and adequately cleaned between wear for activities.
