Why does Crest Pro-Health Toothpaste have a warning about staining?
Current FDA regulations require that products containing stannous fluoride be labeled about their staining potential. But Crest Pro-Health Toothpaste, with our Polyfluorite Systemâ„¢, contains a high-cleaning silica and sodium hexametaphosphate, a unique whitening ingredient, to remove and help prevent external stains. And it’s the only toothpaste to provide protection against cavities, gingivitis, plaque, tooth sensitivity and tartar buildup, and it freshens breath.
