Here's a toothpaste you might accidentally swallow -- a chocolate-flavored toothpaste. The oxymoronic comes together in Crest's latest product especially for those with a sweet tooth.

The Mint Chocolate Trek flavor is part of the new Crest "Be" line, which includes Vanilla Mint Spark and Lime Spearmint Zest as well. The company claimed that the creation of deliciously flavored toothpaste is due to the customers' feedback saying they found the previous toothpaste rather boring.

"Got an adventurous spirit or a sweet tooth? Well, then this is the toothpaste for you," the company put out in a press release for the new line. "Now consumers can explore outside their boundaries, arouse their senses and energize their brushing routine like never before. It opens with a rich, creamy cocoa flavor that provides an indulgent and decadent experience."

Some people are skeptical about the toothpaste tasting like chocolate, since it is sweet, meaning it can be harmful for pearly white. However, there is no need to worry: it only contains flavoring and not the actual cocoa butter. The main ingredient to its teeth-cleaning capability comes from the sodium fluoride, which the Crest product already contains.

John Scarchilli, head of scientific communications for Procter & Gamble, said that getting the flavor exactly right was difficult. "We actually use a proprietary flavoring-and-cooling technology that delays the onset of the mint, to let the chocolate make the first impression," he said. "Holding back the mind long enough -- 30 to 40 seconds -- lets the chocolate be satisfying."

Priced as $4.99 per tube, the chocolate-flavored will hit store shelves in the first week of February. It will certainly be interesting to see consumers' reaction, starting their day and going to bed with a hint of chocolate in their mouths.
