According to scientists in China, the answer for dentures and broken teeth could be in urine (your pee)! Researchers from the Guangzhou Institutes of Biomedicine and Health took stem cells – cells that can become anything in the body – from our pee and made them grow into teeth. While they are confident in the technique used to grow the bones, a professor from University College London, Chris Mason, isn’t completely sold on the idea. Since urine contains several toxins and bacteria, he is worried these chompers can lead to infection.
