The toothbrush has a brush head (10) mounted on a brush body (12), which rotates about an axis (R) and is driven by an eccentric reversible drive (40,50,52). The external drive comprises a drive shaft (50) which runs in a direction orthogonal to the axis of rotation of a brush carrier (20), which has a guiding groove (32) in an axial direction, in which an eccentric spigot (52) is guided. |
