Abstract
Abstract Coated dental textile material is provided which has a fluorine-containing compound distributed through the coating and/or deposited thereon. The fluorine-containing compound provides fluoride ion in a therapeutic amount to inhibit the formation of dental caries when the coated dental textile material is intimately contacted with the teeth and gingiva to remove food deposits. A method of preparing the dental textile material is provided which assures that a proper amount of the fluorine-containing compound is substantially uniformly distributed through the coating and/or deposited thereon. A method of inhibiting the formation of dental caries is also provided wherein the coated dental textile material of the invention is used periodically to remove food deposits from the teeth and gingiva.
