Miley Cyrus is said to have paid a professional to have a brighter smile. In comparison with older photos, the star now appears with a new set of perfect polished teeth, reports a dental expert. "It looks as though she's had some porcelain veneers put on her front teeth. And her small incisors appear to have been covered to make them look longer and more balanced with the rest of her mouth," Star magazine quoted Michael D. Kosdon, as saying. In other news, Miley Cyrus has taped a performance for successful TV show American Idol. The second edition of “Idol Gives Back” airs tonight (April 9) on Fox.
