Find Out How Colgate® Max White One Optic Toothpaste Works

Though I found the blue foam, when brushing, initially disconcerting, this toothpaste actually does what it says it will.  It may only be a temporary optical illusion, but my teeth definitely appear whiter for hours after brushing.  Just be sure to double-check for blue residue on gums and around mouth before leaving the house! :)
