Abstract

A toothbrush includes an elongate body having a handle and a head formed with bristle assemblies each including elastic upper and lower boots on either side of an intermediate layer, an elastic collar extends through the intermediate layer from the lower boot to the upper boot a tuft of bri sties bound by a coupling, the tuft of bristles extends from the coupling in the lower boot through the collar and through the upper boot and therebeyond to a brushing extremity, the upper boot provides lateral elastic compliance between the upper boot and the tuft of bristles through the upper boot, the lower boot provides lateral elastic compliance between the lower boot and the coupling in the lower boot, and the intermediate layer pinches the collar against the tuft of bristles through the collar elasticallv retaining the tuft of bristles through the elastic collar to the elastic collar.
