Olsen Twins Fight Plaque
Mary-Kate and Ashley, the toothpaste, noted as mary-kateandashley in official correspondence, shipped to stores last week courtesy the makers of Aquafresh, retailing for an average price of $2.77 per pump-dispensing tube.

The teen titans were described as being closely involved with the development of their toothpaste selves, right down to the selection of the flavor.

“They absolutely tested it out,” says Michael Pagnotta of the Olsen twin-controlled Dualstar Entertainment Group.

Aquafresh is looking to lock in the preteen set with the brand, billing it as a “landmark in the history of toothpaste marketing,” and not just because the Olsens, now 17, appear as 13-year-olds on the packaging.

Tammy Szatkowski-Reeves, curator of the Sindecuse Museum of Dentistry at the University of Michigan, points out adult celebrities, including Pepsodent purveyor Bing Crosby, were frequently seen on toothpaste tubes in the 1940s and 1950s.

And unlike Olsen twins detangler, Olsen twins nail polish and Olsen twins soothing eye gel masks, sold exclusively at Wal-Mart, Olsen twins toothpaste, Lukas says, “will be distributed everywhere.”
