Abstract: The present invention provides oral care compositions for treating tooth sensitivity. The composition comprises a synergistic mixture containing a copolymer having at least one repeating unit of alkyl vinyl ether functionality and a monomer having at least one repeating unit of ethylenically unsaturated dicarboxylic acid or anhydride functionality present in an amount of about 0.1 to about 50% (w /w) of the total mixture; and a homo polymer having repeating unit of alkyl vinyl ether functionality present in an amount of about 0.1 to about 50% (w / w) of the total mixture. These synergistic mixtures of polymers act as barriers for dentin flow and reduce pain and discomfort caused by tooth sensitivity and exhibits at least 60% average reduction in dentin flow.
