No more dentures

From The New Scientist a team of researchers in Japan have been able to grow new teeth in mice. They take some cells and grow them into a tooth bud which they then transplant in to a mouse. The tooth then grows as normal.
Great news for all of us who occasionally forget to brush our teeth. Or eat sugary foods. Maybe next they can grow us new lungs or hearts. Or replacement limbs.
I wonder if we can order designer teeth next, few vampire like fangs might be cool. Blooooood, I vant to suck your blooood.
