Do tv stars have to get their teeth fixed?

I'm watching deadliest catch, the crab fishing show. Anyways, I can see an actor on the lifetime channel needing nice straight white teeth, but i'm kind of surprised it would matter on this particular show. My guess is they're probably at least made to get them whitened. The tv probably doesn't show them good enough to see if they're actually straight is my only thinking. They sure all look straight though. Maybe they get paid enough to do whatever it takes to make them nice and straight I don't know. opinions? Or the discovery channel pays for it. Hell, it's like $5k just for a root canal and crown these days.
