Next month Crest will be releasing chocolate toothpaste for adults.  The flavor is called Mint Chocolate Trek.  Later in the year, they'll also be releasing flavors called Lime Spearmint Zest and Vanilla Mint Spark.  They aren't adding actual chocolate to toothpaste; the flavors will be totally artificial.  A Crest executive says the toothpaste is targeted at "experiential consumers".
