Abstract
A method and compositions for retarding plaque and calculus by use of a zinc compound which is substantially less astringent than other zinc compounds typically utilized are disclosed. Zinc salts of carboxymethyloxysuccinic acid are effective anticalculus and antiplaque agents and have been shown to be substantially less astringent than other typically used zinc compounds.
