Abstract
An oral care composition includes an effective amount of a basic amino acid in free or salt form; and an effective amount of calcium silicate particles. The calcium silicate particles have an average diameter of less than about 5 microns, such that they can occlude dentinal tubules of the teeth. An oral care method includes applying the composition to an oral cavity of a subject to reduce or inhibit hypersensitivity of the teeth and to achieve other benefits.
