Abstract: A dental coloring stamp has a transfer pad for transferring a dental coloring solution to a precursor of a dental restoration. The transfer pad is at least partially formed of an open-celled elastic sponge and has a free transfer surface. The cross-section of the transfer pad is greater than a circular area of 10 mm in diameter so that a side of a dental restoration precursor can be stamped and thus colored. The invention helps facilitating the coloring of dental restorations.
