PURPOSE: To obtain a dentifrice which is enhanced in the ability to dissolve and remove bacterial plaque, excellent in refreshed feeling in mouth after brushing and in incorporation of fluorine into tooth surface. CONSTITUTION: This dentifrice contains 0.5-95wt.%, based on the total granules, of a water-insoluble alkali compound such as calcium carbonate/magnesium hydroxide and 1-50wt.% of granules which contains a water-insoluble inorganic binder (colloidal silica) and shows a pH of >=10 in aqueous slurry form. The granules are 75-500μm in sizes, preferable disintegrated on the load of 0.1-50 g/particle in strength and produced by the well-known spray-pelletizing process. When a fluorine compound such as sodium fluoride is formulated, a dentifrice excellent in tooth decay prevention can be obtained. In the water-insoluble alkali compound, the ratio of calcium carbonate/magnesium hydroxide is preferably 90/1-8/1.
