In a method for the optical distinction of a dental material applied to a substrate from natural teeth, false teeth or parts thereof, 0.00001 to 1% by wt. of a fluorescent substance having an absorption maximum in the wave length range of 360 to 480 nm and a fluorescence maximum in the wave length range of 480 to 600 nm is incorporated in the dental material. The dental material is applied to the substrate and irradiated with a light source emitting light of a wave length in the region of 360 to 480 nm and is then viewed through a light filter filtering out at least partially the light of a wave length in the region of 360 to 480 nm. The dental material for use in the process can comprise coumarin derivatives, phthalimide derivatives, fluoranthene derivatives, perylene derivatives, xanthene derivatives, thioxanthene derivatives, pyrano-benzopyran-2, 5-dione derivatives, pyrano-quinoline-2, 5-derivatives, pyrazole quinoxaline derivatives, 2-pyrono-isoquinoline-3, 6-dione derivatives, benzimidazo-benz-isoquinolin-7-one derivatives, acridine derivatives or mixtures of the above-mentioned derivatives as fluorescent substances.
