Abstract
A toothbrush head is provided with a plurality of separate cleaning areas. The distal end and the proximal end of the head include cleaning elements mounted to generally non-movable bases. The central portion of the head includes resilient pods carrying cleaning elements in such a manner that the cleaning elements are capable of bending away from their initial position and then returning to their initial position. In another aspect of the invention the pods are made as a separate unitary subassembly wherein the cleaning elements are bristles in an IMT procedure. The unitary subassembly is secured to the remainder of the cleaning head of the brush during the molding operation of the remainder of the head and the handle. In this aspect of the invention non-movable bases may be provided or may be omitted.
