The invention discloses a method for glazing a porcelain-fused-to-metal false tooth. The method comprises the following steps: spraying and washing a false tooth germ body with steam; performing brush dyeing by dyeing porcelain, and gradually dyeing developmental grooves of a rear tooth from light to deep according to a sequence of auxiliary groove-main groove-fossa; brushing glaze water to a lingual side and a lip side of the false tooth germ body as well as a 3/5 area, close to a cut end, of an occlusal surface of the rear tooth, and not brushing the glaze water to a 1/3 area, close to a central groove, of the rear tooth; selecting the dyeing porcelain for gradual brush dyeing from deep to light according to color comparison of a colorimetric plate and the color of a genuine tooth; preheating and baking in a furnace. According to the method, pre-dyeing is gradually performed from light to deep by the dyeing porcelain and then the glaze water is brushed to obtain a glaze layer with balanced color and luster; dyeing is performed from deep to light after color comparison, so that the glaze layer brushed on the surface of the false tooth germ body forms color and luster matched with those of the genuine tooth; due to the adoption of multi-time brushing in a specific direction, the color and luster balance degree of the glaze layer is increased and the appearance quality of a product is improved.
