[1] A method for producing granules for a tooth polishing agent comprising mixing a water insoluble powdery material with a silicic acid salt using a vessel rotatable granulator to granulate the mixture said method involving a step of carrying out the granulation while supplying droplets of an aqueous solution of the silicic acid salt to the water insoluble powdery material using a multi fluid nozzle and said method enabling the production of granules for a tooth polishing agent which have proper collapse strength and excellent wet collapse strength with high yield； [2] granules for a teeth polishing agent which can be produced by the aforementioned method； and [3] a teeth polishing agent which contains the granules for a teeth polishing agent.
