A device for providing a coloured covering of the teeth, consisting of a light mask (1) of out of coloured, non-toxic plastic and/or resin material, like polyester spiced with colour pigments, exactly shaped onto the tooth mould (2) of each user and that therefore may be applied to the real lower and/or upper set of teeth, thus giving a smile an aesthetic and psychological effect never seen before.
