Never Brush Teeth Again With Protective ‘Armor’ That Prevents Decay
Scientists in Japan have created a hard-wearing, artificial enamel that covers your teeth and is only 0.004 millimeters thick.
Scientists from Kinki University in Japan have created an artificial enamel that covers and protects your teeth. The thin film (which is only 0.004mm thick) can be used to prevent decay, repair damaged enamel, or make your teeth less sensitive. It is made from hydroxyapatite (the main mineral in tooth enamel) and is currently transparent, although it’s possible to make it white for use in cosmetic dentistry.
AFP reports that researchers are currently experimenting on disused human teeth and the technology is patented in Japan and South Korea, with applications underway in the U.S., Europe, and China. The hard-wearing and flexible film could be ready for cosmetic use within three years, and for dental treatment within five.
