Japanese scientists have invented a tooth coating that could revolutionize many aspects of dentistry.
The 'tooth patch' consists of a microscopically thin film of a hard-wearing and ultra-flexible material comprised of the same mineral found in natural tooth enamel. Once applied it can prevent tooth decay and even cure sensitive teeth. The material is staggeringly thin at just 0.00016 inches thick and is made by firing lasers at compressed blocks of hydroxyapatite in a vacuum.
"This is the world's first flexible apatite sheet, which we hope to use to protect teeth or repair damaged enamel," said professor Shigeki Hontsu. "Dentists used to think an all-apatite sheet was just a dream, but we are aiming to create artificial enamel."
"Scientists in Japan have created a microscopically thin film that can coat individual teeth to prevent decay or to make them appear whiter, the chief researcher said."
