This document discusses sports dentistry and the importance of mouth guards for preventing injuries to teeth and jaws for athletes. It recommends that every team have an official team dentist to oversee a mouth guard program and fit each player with a custom-made mouth guard. Custom-made mouth guards are preferred by players over stock or mouth-formed types. The duties of the team dentist are to examine players' teeth, take impressions to make custom mouth guards, fit the mouth guards, and educate players and coaches on their benefits for reducing injuries.
