To provide a flocked file for clearing injury of a dental root canal during endodontic treatment, in total.

This flocked file 70 includes a shank 72 having a peripheral face 74, and fiber 76 installed to the peripheral face 74 by a method such as transplantation. The peripheral face 74 has at least one flocked face segment 80. The peripheral face 74 includes the flocked face segment 80 dispersed with the fiber 76 over the segment 80, and at least one grinding face segment 78 suitable to grind or scrape a wall of the dental root canal. The fiber 76 can be made of various materials, and can have various textures, deniers and lengths, and flexibility. The fiber 76 rubs out and removes a potential stimulus of a dental root canal structure including a recessed region 40 and a accessory canal 50 without unnecessary reshaping or without requiring removal of dentin from the dental root canal.
