    Abstract: A chewing gum is disclosed which is for cleaning and imparting a high degree of polish to the teeth; the chewing gum comprises a chewing gum base, at least one non-toxic source of acid in a particular amount, and calcined kaolin particles, the median diameter of which is approximately 2 micrometres or less, and substantially all of the particles being less than approximately 20 micrometres 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, can also inhibit the reformation of dental plaque.
