Miley goes 4 Porcelain

Teenage pop sensation Miley Cyrus is showing off a new set of perfect polished teeth, according to a dental expert.

After studying before and after images of the 15 year old Hannah Montana star, a leading California dentist is convinced she has paid a professional to make her smile even brighter.

Michael D. Kosdon tells America's Star magazine, "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."
