Dentists in Switzerland have developed a gel that creates a protective layer for coating tooth enamel.

Swiss company vVardis, a maker of oral health products, has created the gel, which infuses tooth enamel with calcium, phosphate and other essential substances.

As the gel clogs the holes in the enamel, teeth are restored and whitened. Meanwhile, as the gel protects, it absorbs the acids encountered from eating, drinking and smoking.

According to its makers, the gel could one day prove to be a drill-free alternative to treating and filling cavities.
