We've been noticing Miley Cyrus's much-straighter smile lately, and we're glad someone else (aka Star magazine) noticed: her bottom teeth look straighter, and her top front teeth are less prominent. Could she have gone the way of her idol Hilary Duff and gotten veneers? "It looks as though she's had some porcelain veneers put in her front teeth," Star's dentistry expert says. "And her small incisors appear to have been covered to make them look longer and more balanced with the rest of her mouth."
