PEE IS THE KEY Human urine has been used to grow rudimentary teeth by scientists in China. The pee was used as a source for stem cells which were mixed with other material from a mouse and implanted into the animal. The result was a “tooth-like structure” which the team hope could pave the way for tooth regeneration.
MOUTH MEMORY Losing your teeth could make you lose your memory, according to research in the European Journal of Oral Sciences. The number of natural teeth was said to be “significantly” linked to performance in memory tests. One theory is that those with fewer teeth produce fewer sensory impulses to the part of the brain that forms and retrieves memories.
BEYOND TEETH People could eventually develop pufferfish- like beaks because teeth are “no longer fit for purpose”, say Sheffield University scientists. As we all live longer, having a limited supply of teeth is impractical and evolving such beaks could result in more robust, self-replacing teeth.
