A partial set of dentures used by former British leader Winston Churchill - described as the teeth that saved the world - sold at auction for 15,200 pounds ($23,723.) The upper dentures, one of several sets specially made for the wartime prime minister, were crucial for maintaining his distinctively slurred speaking style famous from World War II-era radio broadcasts. They are on show in a glass cabinet alongside other famous teeth - including dentures worn by Queen Caroline, the estranged wife of King George IV. The false teeth were bought Thursday by a British collector of Churchill memorabilia at an auction in England at three times the estimated price.
