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, with a central axial tunnel expending part way into the fiber bundle, similarly made up of welded fibers. The brush head is produced by partially melting one end of the fiber bundle to form the bottom plate, with the bundle moved into contact with a heated mandrel, while the fibers remain substantially parallel.
