Ginnifer Goodwin Kicks-Off the LISTERINE 21-Day Challenge

Ginnifer Goodwin, better known as Snow White on ABC'S "Once Upon a Time," takes a break from Fairy Tale Land and the Evil Queen to join forces (for good) with LISTERINE. The LISTERINE 21-Day Challenge encourages everyone to commit to "swish" with LISTERINE for 21 days. For every person who signs up, a contribution will be made to Smiles Across America, a division of Oral Health America that brings oral health care services to children in need.
