Sam had the whitest teeth, IIRC, but that was the only thing that made me think he could proceed to a media career.
As an aside, I am old and had basic NHS dentistry as a child. My teeth are anything but pearly white, but fortunately still there (for now). I still do a double take at the gleaming white, totally regular teeth so many young people have now. I hope whatever it is they're having done is not going to cause them problems later on.
