The object of the invention is to provide a tooth-cleaning composition
capable of well removing staining matters such as tar of tobacco and tea
incrustation from teeth merely by cleaning teeth with it in a simplified
manner for a short period of time not damaging the surfaces of teeth to
thereby estethicize the thus-cleaned teeth, and to provide a method for
producing the composition. The object can be attained by a tooth-cleaning
composition that contains silicon nitride having a mean particle size of
from 0.5 to 10 .mu.m. The method for producing the tooth-cleaning
composition comprises mixing powder of silicon nitride, powder of natural
wax, and a solution that contains a water-soluble polymer followed by
stirring the resulting mixture until its viscosity at 25.degree. C.
reaches from 100,000 to 500,000 cps. Not containing expensive diamond
powder but containing silicon nitride powder, a type of ceramics of high
hardness, the tooth-cleaning composition of the invention effectively
removes staining matters such as tar of tobacco and tea incrustation from
teeth merely by cleaning teeth with it in a simplified manner.
