Abstract
The present invention relates to a toothbrush having a handle formed of interlocking opposed S-curved sections, the first being relatively rigid and the second relatively resiliently flexible, the opposed S-curved sections forming a generally elongated figure 8, having an aperture within each segment of the figure 8, such that during brushing the user can manipulate the relatively rigid and resiliently flexible section to position the bristle bearing face of the toothbrush to conform to the arcuate configuration of the dentiture.
