Abstract

A head for a toothbrush including a neck and, first and second sets of one or more bristles each. The first and second sets are indirectly supported by the neck and movable relative to each other such that at least one component of this relative movement causes the bristle(s) of the first set to be raised and/or lowered relative to the bristle(s) in the second set. The first and second sets of bristles both are movable relative to the neck.

2. The head of claim 1, wherein the first bristle support is rotatable in an oscillating manner about the axis.

3. The head of claim 1, wherein the first bristles extend substantially perpendicular from the first bristle support.
