Grow your own teeth: Breakthrough in the lab may spell the end of dentures

By Fiona Macrae - Scientists have made teeth from stem cells in a world first that could make dentures a thing of the past.

They looked like normal teeth, were sensitive to pain and chewed food easily.

While the experiments were on mice, they pave the way for people to 'grow their own teeth' as required.

The technique could also be adapted to other organs, allowing hearts, lungs and kidneys to be grown inside the body to replace parts worn by age or damaged by disease.

The Japanese study focused on stem cells - 'master cells' with the ability to turn into other cell types.

The researchers from the Tokyo University of Science identified two types of stem cell, which together contain all the instructions for a fully grown tooth.
