Chinese Scientists Regrow Tooth Enamel In 48 Hours With Phosphate Gel

hackingbear writes: A team of researchers at China’s Zhejiang University were able to create a gel that makes tooth enamel repair itself, they wrote in the science journal Science Advances, a development that could spell the end of fillings as an (unreliable) method to repair cavities which are one of the most prevalent chronic diseases in humans. The gel succeeded in making the enamel repair itself within only 48 hours. Though it now only manages to generate a layer of about 3 micrometres — about 400 times thinner than undamaged enamel, the researcher says the gel could be repeatedly applied to build up this repair layer. The team is now testing the gel in mice and hopes to later test it in people.
