A tool head for an electric toothbrush has at least one tool carrier movably supported on a base part by means of a bearing device. The bearing device includes rotational support means for rotatably supporting the tool carrier about an axis of movement and axial support means for axially movably supporting the tool carrier along the axis of movement, and drive means for driving the tool carrier in an oscillating manner to rotationally oscillate about said axis of movement and to axially oscillate along said axis of movement. The drive means include a cam surface for transforming a rotation of said tool carrier into axial movement of the tool carrier relative to the base part along the axis of movement.
