The present invention provides oral care compositions comprising, by total weight of the composition: (a) 15 to 35 weight % calcium carbonate; and (b) 5 to 25 weight % talc. In one aspect, the total concentration of talc and calcium carbonate in the composition is greater than 35 weight %. In another aspect where the total concentration of talc and calcium carbonate is 35 weight % or less, the composition also includes an additional structuring agent, which comprises at least one of: (i) a cellulose ether thickening agent; and (ii) an inorganic thickening agent selected from thickening silica, a clay thickening agent, and mixtures thereof.
