Our bodies possess remarkable natural healing capabilities. Throw in a little modern medical science and our ability to bounce back from an injury looks even better. Broken bones fuse back together. Ageing eyes return to 20/20 vision. With a few snips, a doctor can even re-string a major-league pitcher’s throwing arm. When it comes to our teeth, however, our options are far more limited. Lose an adult tooth and there’s no growing it back.
But is there another way? According to a BBC science article, a team of U.S. scientists at Oregon State University may have discovered the key to growing new teeth in a laboratory. They successfully pinpointed a gene in mice responsible for the production of the hard, enamel coating that give our chompers their bite. In addition to playing a role in nerve and skin development, the Ctip2 gene plays a key role in the production of ameloblasts, the cells that secrete enamel.
