A super-tapered toothbrush (normal) that effectively removes plaque by regular brushing. The surprisingly 48 holes have a large amount of hair transplant and a large contact area with teeth, so you can easily and efficiently remove plaque by regular brushing. Combination of soft outer and hard inner flocking. In addition, the tips of the hair are ultra-tapered hair that goes into the periodontal pocket to remove dirt, and flat hair that removes dirt from the surface of the tooth.
