Japanese Researchers Invent ‘Tooth Patch’ to Prevent Tooth Decay
In Japan, scientists have created a new tool that many believe will help prevent tooth decay in the future. They call it the “tooth patch,” an ultra-flexible biocompatible film that scientists have designed to fit snugly over the surface of teeth. The film is made entirely of hydroxyapatite, the natural mineral from which tooth enamel is made. The developers of the tooth patch hope that it’s enamel-like composition will make it an effective shield to prevent tooth decay, as well as a restorative material that can be used to repair teeth with pre-existing cavities or dental caries.
