Disclosed are a brush head structure having three working surfaces for a toothbrush, and vibrating electric toothbrush having the same. The brush head structure having three working surfaces comprises a bristle frame and bristles. The bristle frame is U-shaped or H-shaped, and is entirely or partially made of soft rubber. The U-shaped bristle frame comprises two side plates, one base plate, and two curved connection plates made of soft rubber, wherein the bristles are implanted on inner walls of the side plates and the base plate, a bristle cavity is formed thereby, and rear ends of the side plates are connected to two ends of the base plate via the curved connection plates. The H-shaped bristle frame comprises two side plates and a cross plate connected to middle portions of the side plates, wherein the bristles are distributed on inner walls of the side plates and two sides of the cross plate, an upper and lower bristle cavity formed thereby, and the bristles on the H-shaped bristle frame are cylindrical and formed with the H-shaped bristle frame as an integrated structure by means of soft rubber injection molding. The bristle frame of the brush head of the present invention is made entirely or partially of soft rubber, such that the bristle frame has superior flexibility, the brush head better accommodates the size of a tooth automatically when brushing teeth, and does not easily damage gums.L'invention concerne une structure de tête de brosse ayant trois surfaces de travail pour une brosse à dents, et une brosse à dents électrique vibrante la comprenant.
