A method of making a dental restoration has the step of providing a precursor of the dental restoration. The dental restoration has at least a first and a second surface portion which are delimited by a physical boundary structure. The method further has the steps of applying a first coloring solution associated with the first surface portion onto the first surface portion, sintering the dental restoration precursor, and removing the physical boundary structure.
