Did you know that those teeth whisked away by the tooth fairy many moons ago are now actively sought for their potential in stem cell research? That's one magic potential of teeth explored in a remarkable, slightly creepy, tooth sculpture 'Palaces', now exhibiting at London's Science Museum.

Artist Gina Czarnecki has created a 2 metre high resin palace which is slowly gathering milk teeth donated by members of the public. The teeth have accumulated over the past few months, along with touching stories of how the teeth were lost (or rediscovered). Each tooth is hand-glued to the resin sculpture by Gina herself. Gina has been working with stem cell biologist Sarah Rankin to explore how milk teeth can be used as sources of stem cells for helping the body to regenerate.

Gina is a bioartist who works with the ethics of biotechnology. If teeth seem like a twee subject to explore this by then you'd be surprised – Gina chose teeth because you can only donate parts of your body when you are living. After death you no longer have any say (even through your last written testament) where your body goes unless you donate it to medicine.
