Tooth-cleaning composition and method for producing it

   
   

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.
