Abstract

The subject of the invention is a cosmetic preparation for teeth which is composed of one or more film-forming polymers--at least one of which is water soluble, partly soluble, emulsifiable or dispersible--and coloring agents. The composition ensures the aesthetic appearance of the teeth and can--by contrast with earlier products--be removed easily and rapidly.
