Abstract
An athletic mouthguard for use by participants in contact sports to simultaneously protect and topically treat the teeth.

The fluoride compound is released from the molded resin mouthguard to the wearer's teeth over extended periods of use.
Claims1
A generally U-shaped athletic mouthguard molded from a composition of liquid impermeable ethylene vinyl acetate copolymer and not more than 5% by weight fluoride compound selected from the group consisting essentially of sodium fluoride, stannous fluoride, and sodium fluorosilicate;
- said liquid impermeable ethylene vinyl acetate copolymer having a melting point below the fluoride compound whereby when heated to a temperature in excess of normal human body temperature can be molded to receive an impression of the wearer's teeth and when cooled to the normal human body temperature is resilient and shape retaining.
