PROBLEM TO BE SOLVED: To easily and quickly remove the dirt mainly consisting of the stain adhered to the surface of teeth and improve the feeling of use and easiness by constituting tooth brushing dentifrice materials by use of a fiber assembly containing a superfine fiber having a sharp edged cross-sectional form in a specified weighting capacity. SOLUTION: The tooth brushing dentifrice materialsare formed in a shape such as sheet or stick suitable to be held in one's hand to clean the teeth to clean the teeth by use of a fiber assembly containing at least partially containing a modified cross-sectional super fine fiber having sharp edges with its weighting capacity being set to 20-300 g/m2. The degree of single fiber of the modified cross-sectional superfine fiber is preferably set to 0.0001-1.0 d(Denier), and polyester, nylon, polypropylene, ethylene-vinyl alcohol copolymer or the like is preferably used as the material. The tensile strength of the fiber assembly is preferably set to 1-30 kg/width 2 cm, and the ratio of the hydrophilic fiber contained in the fiber polymer is preferably set to 10/90-90/10 (wt.%).
