Sports Dentistry is the branch of sports medicine that deals with the prevention and treatment of dental injuries and related oral diseases associated with sport and exercise.
This is why most of the times these atheletics use mouthguards to protect their teeth. Definition of a mouthguard: 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 mouthguard 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. Mouthguard materials by nature must have shock absorption qualities. They must be resilient and yet soft enough to absorb impact energy and reduce transmitted forces. The thickness of mouthguard material is directly related to energy absorption and inversely related to transmitted forces when impacted. However, wearer comfort is also an important factor in their use.
