Why brush your teeth if you have nano?

Researchers at the Universität Witten/Herdecke just reported a new invention that will make brushing your teeth a thing of the past. Using nanotechnology, the German researchers developed a lacquer that will protect teeth. When a person chews, tiny nanoparticles in the lacquer burst and release fluorides that prevent cavities. The nano-based lacquer also prevents tartar and comes in a menthol version that keeps your breath fresh at all times.
