Too Cool – Grow new teeth!

Folks who read Slashdot have probably already seen this, but apparently some researchers in the UK have used stem cells to grow new teeth in lab animals.. From the article:
“Stem cells, the so-called master cells, would be programmed to develop into teeth and then transplanted into the patient’s jaw where the gap is.”
“It is thought it would then take two months for the tooth to fully develop. ”
For those of us with less than perfect teeth (HI!), this sounds awfully cool.
