Abstract
A toothbrush head containing a first tuft block mounted for oscillating about a centrally located axis and an elongated second tuft block mounted for rotational movement about an axis eccentric to its center point. One of the tuft blocks has a recess for receiving an extension of the other tuft block to create a drive connection between the two tuft blocks, such that when one of the tuft blocks is driven by a drive structure the rotational movement of that tuft block causes the other tuft block to oscillate.
