Stem cells is the issue on this one, apparently they don't hang around later in life.
On the bright side, this is one of the places where current stem cell research has already panned out, so if you wan to pick up new teeth just head over to your local University Dental Implant facility and sign up to get some teeth regened and nine weeks later you'll have your tooth:
