A piece of artwork made up of children's milk teeth is being created at Exeter's Royal Albert Memorial Museum... and the artist is inviting parents to donate any that the tooth fairy has left behind.
The stalagmite crystal sculpture will be included in an exhibition exploring the life-giving potential of discarded or shed body parts.
Parents who'd like their children's baby teeth to form part of it can leave them in a special collection box in the museum's garden reception area.
