Abstract
A dental cleaning implement such as a toothbrush, having longitudinally disposed first and second parts flexibly joined together. Between the first and second parts is a rotatable member such that when the implement bends the first parts adjacent to the member bear upon the member. The rotatable member has circumferentially disposed relatively softer and harder regions, so that as the member is rotated the parts can be caused to bear compressibly upon selected softer or harder regions.
