Abstract
Dental cream comprising between about 35 and 60% by weight of abrasive consisting essentially of calcium carbonate and alumina, with the alumina at least about 0.05% by weight of the dental cream and in an amount not greater than the calcium carbonate. The dental cream also contains a water-soluble monofluorophosphate salt in an amount which provides about 0.01-1% by weight fluoride in said dental cream and about 0.1-1.5% by weight of an alkali metal tripolyphosphate as an agent to improve the ability of the dental cream to retain monofluorophosphate as fluoride. The dental cream may also contain 0.025-0.25% by weight of a dissolved or dispersed silicate.
