Doctor Who (Matt Smith)

Don't know if it's true or not; but, I remember reading somewhere that Billie Piper had dental veneer work done in the time frame between when she was the regular companion and when she reprised the role in later episodes. Her speech was certainly different and it wasn't just her accent. All in all Billie Piper's Rose is my favorite companion to date, though I think some of the finest acting for a companion character came out of Catherine Tate at times.
