New Tooth Patch May Help to Prevent Dental Decay
Japanese scientists developed a microscopically thin film to help prevent tooth decay or to make teeth appear whiter. This film called the “tooth patch” is a hard-wearing and ultra-flexible material made from hydroxyapatite, the main mineral in tooth enamel, that could also mean an end to sensitive teeth.
Professor Shigeki Hontsu, at Kinki University’s Faculty of Biology-Oriented Science and Technology in western Japan, stated that it is the world’s first flexible apatite sheet, which they hope to use in order to protect teeth or repair damaged enamel
