Miley Cyrus was a cute child star with some pretty rough teeth. She had plenty of work done to get them evened out and whitened, but her overall change takes away from the work she had done. She came out as such a different person from her childhood persona that few noticed the work she had done. While some love her and some hate her, it time, those teeth will still be the biggest change to her appearance, no matter how wild she goes with her wardrobe.
