Methods and kits for removing calculus using a metal ion and bicarbonate

Abstract

Methods and kits for removing calculus from a tooth, wherein the method can include applying a component A to the tooth, wherein component A comprises: a metal ion selected from the group of lithium ion, magnesium ion, calcium ion, a precursor thereto, and a combination thereof; and an aprotic base having a pKb in water of greater than 15.4, or a precursor thereto; applying a component B to the tooth, wherein component B comprises a bicarbonate ion or a precursor thereto; wherein components A and B are applied simultaneously or sequentially to the tooth, thereby generating a gas to soften and/or loosen at least part of the calculus on the tooth; and removing at least a part of the calculus from the tooth.
