Abstract
A tooth cleaning apparatus has a working surface formed by fibrous cleaning elements of different lengths and of very small diameters at their working ends. The cleaning elements are fixed on a base fabric, which is reinforced by a foam layer and thus forms a deformable hollow unit that is then attached to a handle. The pile-like cleaning elements facilitate very effective cleaning even of the fine surface contours of curved tooth surfaces.
