I’ve been telling you about my experience with Aquafresh White Trays and now there’s a way for you to win your own whiter smile from Aquafresh.

It’s easy: just go to Guess This Celebrity Smile for a chance to guess whose famous face the smile belongs to (and how much it’s insured for with Lloyd’s of London) and you could be a winner. A hundred entrants will win an Aquafresh White Tray Perfect Fit Kit. The kits include an Aquafresh White Trays Whitening Treatment, White & Shine Toothpaste and other fun stuff.

The face behind the smile will be revealed on the site on May 10.
