Toothing
I was talking with my dentist about regrowing teeth, from an article I saw some time ago about using stem cells to grow mouse teeth on rooster beaks. I was discussing the possibility that we might get to grow our teeth again, specially after traumatic (read: accidents) events. Of course, this dentists will like a lot: instead of fillings or crowns or whatever, just grow another tooth.
Now they have mouse teeth on mouse mouths. Would you be for one?

UPDATE: Here is the link to the original paper about chicken with mouse teeth, Kings' College announcement, a link to a similar article on The Economist, and the company founded to capitalize on Regenerative Dentistry, called odontis.
Now, aren't you happy that Bush and his rabid inquisitors forbid cell stem research here in the USA?
