A palace for the tooth fairy made entirely from teeth

When you lose a tooth, do you put it under your pillow and wait for the tooth fairy to call?
An artist in Liverpool had a very different idea and decided to create a sculpture decorated with real teeth.
It's been named the Tooth Fairy's Palace and has a frame made of clear resin into which teeth are carefully glued.
The piece is being built to raise awareness about stem cell research and what it means to science.
