Sports Guard

A sports-guard is a protective device for the mouth that covers the teeth and gums to prevent and reduce injury to the teeth, arches, lips and gums. A mouth-guard is most often used to prevent injury in-contact sports, as a treatment for  bruxism  or TMD, or as part of certain dental procedures, such as tooth bleaching.

Depending on application, it may also be called a mouth protector, mouth piece, gumshield, gumguard, nightguard, occlusal splint, bite splint, or bite plane.
