摘要：
The invention is directed generally to an electric toothbrush and particularly to a brush head for such an electric toothbrush, having a preferably substantially plate-shaped bristle support including mounting means for the movable mounting of the bristle support, said bristle support carrying several outer bristle tufts and several inner bristle tufts, said outer bristle tufts having a greater height than said inner bristle tufts, such that in the working surface defined by the free ends of the tufts there is formed a central depression which has a groove-shaped concave bottom curved in one direction and extending substantially straight in the direction vertical thereto. According to the invention, at least one of the outer bristle tufts has a chamfer on its outer lying edge of its free end close to the circumferential side of the bristle support.
