[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.
