Why does Crest Pro-Health Toothpaste feel gritty?
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.
