The present invention relates to a toothbrush head for an electric toothbrush with a brush head holder on which a bristle holder having a bristle cluster is movably arranged. It is provided that locking means are provided on the attachment section of the brush head holder, which, when the brush head holder is pushed onto the handpiece of the toothbrush with a linear, axial motion engage with the engaging means provided thereon. In order to achieve more efficient cleaning, it is further provided that several groups of bristle tufts are fixed on the motorized drivable bristle holder, and are inclined in different directions, and have different cross-sections, preferably also varying from the circular cross-sections, in order to better penetrate the gaps between teeth and effectively remove plaque. Preferably, a stationary bristle holder is arranged on the toothbrush head adjacent the movable bristle holder, to which stationary bristle holder several groups of bristle tufts are affixed and are inclined in different directions, and preferably have differing cross-sections.
