Contact sports carry a significant risk of<unk>  injury, which can be reduced by wearing a mouthguard or helmet. Mouthguards are often less effective if not fitted properly to the wearer. Despite their wide availability, the use of mouthguards is relatively uncommon. Many people do not use them even in situations that carry a high risk of<unk>  injury, or when their use is mandated. In addition, mouthguards may be dislodged from the wearer's mouth, leaving the teeth unprotected. Certain occlusal traits, such as class II maloclusions and increased overjet, are associated with a higher incidence of<unk>  trauma. These traits can be corrected by an orthodontist.
