The tooth fairy ought to pay extra for this one.

Retired U.S. Olympian Bryan Clay, who won the gold medal in the decathlon at the 2008 Games in Beijing and a silver in 2004, dusted off his javelin skills to remove his daughter's loose tooth.

What you use javelins for once you're retired. <a href="http://t.co/gVwqK75bVa">pic.twitter.com/gVwqK75bVa</a> —@bryanclay

Clay, 35, said in a reply to a tweet that the stunt was his daughter Ellie's idea. She didn't appear any worse for wear, apart from some blood in her mouth.

Clay even attracted an offer from a fellow Olympian to practise some more amateur dentistry.
