You may notice Crest Pro-Health Toothpaste feels a little different in your mouth. It is due to the presence of the ActivClean™ crystals. As you begin to brush, the ActivClean™ crystals immediately begin to dissolve to form a protective barrier that helps prevent stains from attaching to the tooth’s surface and helps prevent tartar buildup.
ActivClean crystals are part of the special whitening ingredients contained in Crest Pro–Health Toothpaste. They are a sodium hexametaphosphate polypyrophosphate compound that forms a barrier on your teeth to help protect the surface from stain and tartar–buildup.
