a) Mouth guards:
Dental mouth guards have long been used and are designed to provide protection to the teeth, gums, and supporting tissues from trauma, injury, and damage. Mouth guards are most often worn by athletes to prevent injury in sports and are also helpful for people wearing braces or bridges, since they provide protection to them, as well. Mouth guards provide protection for the soft tissues of the cheek lining, lips, and tongue by covering the upper teeth.
