A method and system for applying colored dental adhesive and a high-resolution decal to the surface of a person's tooth. The colored dental adhesive is formed by combining dental adhesive with a food grade colorant. The high-resolution decal is formed by printing a design on a paper substrate. Before application of the colored dental adhesive, the tooth is cleaned and etched with a phosphoric acid compound. The colored dental adhesive is applied to the surface of a tooth. The decal is then placed on colored dental adhesive, and the colored dental adhesive is cured. Additional layers of dental adhesive may be applied on top of the decal.

Fibers, for example fiberglass fibers, are added to dental stone powders to provide for reinforced dental stones. Dental stones are made by combining dry components, including binder and fiber glass, adding water to the resulting mixture and setting the mixture in a dental mold. The dental stones are reinforced by the fibers, and allow for reduced breaking or chipping during handling.
