ABSTRACT:
The present invention relates to methods and agents for preventing and reversing the staining of teeth caused by the nonenzymatic browning of proteins in the oral cavity. Suitable agents for the inhibition of nonenzymatic browning may be formulated as rinses and toothpastes, and include cysteine and cysteine derivatives. These preparations may further include known anti-plaque agents, such as chlorhexidine.
