摘要

PROBLEM TO BE SOLVED: To process a tip portion of a brush in manufacturing various toothbrushes so as not to damage the gingiva. In addition, a large amount of toothbrush processing is required and it must be completed in a short time. In addition, the issue was the manufacture of toothbrushes that would increase added value by introducing new technology into the processing. SOLUTION: The brush tip portion of various tooth brushes is processed into a spherical shape, and the inside and outside thereof are impregnated with calcium, calcium carbonate, calcium phosphate, calcined calcium, etc., and the brush tip is bonded at the time of dissolution. In order to prevent the above-mentioned calcium, the above-mentioned calcium is added to dissolve the tip of the brush and process it into a spherical shape. By this technique, the brushes standing in a forest do not dissolve and bond with each other, and the calcium is impregnated inside and outside the dissolved spherical portion.
