Abstract
An improved chewing gum capable of cleaning and imparting a high degree of polish to the teeth comprises a chewing gum base, at least one non-toxic source of acid, and calcined kaolin particles, the median diameter of which is about 2 micrometers or less, substantially all of the particles being less than about 20 micrometers in diameter. Such a chewing gum cleans and imparts a high degree of polish to the teeth without unduly abrading or scratching them. When regularly chewed, such a gum, in addition to cleaning and polishing the dental enamel, also inhibits the reformation of dental plaque.
