ABSTRACT:
A brush head for cleaning and massaging the teeth and gums is disclosed having a bundle of fibers welded together to form a bottom plate. The bottom plate has formed structures produced by partially melting one end of the fiber bundle while pressing the bundle into a shaped recess in a heated tool. The shaped structures allow interlocking of the brush head with mating structures in a driving devise.
