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 bristles 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 elastically retaining the tuft of bristles through the elastic collar to the elastic collar.
A toothbrush comprising an elongate body including a handle and a head formed with bristle assemblies each comprising an elastic collar extending through a layer, a tuft of bristles extending through the elastic collar to a brushing extremity, the layer pinching the elastic collar against the tuft of bristles the elastic collar elastically and pivotally retaining the tuft of bristles to the head, and the layer formed with an inwardly-directed continuous edge against and surrounding the elastic collar and sufficiently rigid along a plane perpendicular relative to the elastic collar and the tuft of bristles to enable the inwardly-directed continuous edge to pinch the elastic collar against the tuft of bristles.

A toothbrush comprising an elongate body including a handle and a head formed with bristle assemblies each comprising an elastic collar extending through an opening extending through a layer from a lower surface of the layer to an upper surface of the layer, a tuft of bristles extending through the opening and the elastic collar from under the lower surface to a brushing extremity beyond the upper surface, the layer pinching the elastic collar against the tuft of bristles, the elastic collar elastically and pivotally retaining the tuft of bristles to the head, and the layer formed with an inwardly-directed continuous edge against and surrounding the elastic collar and sufficiently rigid along a plane perpendicular relative to the elastic collar and the tuft of bristles to enable the inwardly-directed continuous edge to pinch the elastic collar against the tuft of bristles.
