Abstract
A toothbrush comprising a handle and a head supported at one end of the handle. The head includes a portion extending from the handle and having bristles mounted thereon. The head also includes a series of bristle tuft carriers based from the handle extension portion. Each bristle tuft carrier retains at least one tuft of bristles. A region between the bristle tuft carriers and the handle extension portion includes an elastomeric material configured to provide resilient flexing of the bristle tuft carriers with respect to the handle extension during tooth brushing, so that the bristles and the bristle tuft carriers move relative to the bristles on the handle extension portion.
