Abstract: An ornamental metal foil applique for adhesive securement to a dental substrate, comprises a metal foil body having main top and bottom faces of a predetermined shape, preferably with a maximum facial area dimension not exceeding 1 centimeter. The main bottom face may be microetched over at least a major portion of its facial area to enhance the adhesive securement of the applique to the dental substrate and/or have a mesh backing member or other formaminous backing structure secured to such face of the metal foil body. The applique of the invention may be usefully employed for ornamenting a dental substrate of an individual whose mouth contains such dental substrate, by bonding the main bottom face of the shaped metal foil to the dental substrate with an adhesive medium so that the ornamental metal foil applique is in a selected display position on the dental substrate.
