Abstract
The present invention relates to compositions and methods for inhibiting plaque. In particular, this invention relates to oral compositions comprising: (a) a safe and effective amount of a carboxy-containing copolymer having the formula ##STR1## or the salts thereof, wherein n is in the range of from about 200 to about 14,000, m is in the range of from about 2 to about 5,000, and p is in the range of from 1 to 3; and (b) a pharmaceutically acceptable carrier. These compositions inhibit plaque without staining the teeth which are contacted with the composition. This invention also relates to a method of inhibiting plaque on tooth surfaces in the oral cavity. This method involves applying a safe and effective amount of the carboxy-containing copolymer active agent to the oral cavity. Such an application is typically made by applying the above-described oral compositions containing the carboxy-containing copolymer to the oral cavity. The application does not stain the teeth on which it is made.
