Abstract
A brushhead for a toothbrush having a particular bristle configuration which includes a plurality of bristle tufts arranged in three columns and nine rows, wherein the distal end two adjacent rows and the proximal end two adjacent rows and an intermediate row have longer bristles than the remaining bristle tuft rows. The distal, intermediate and proximal bristle tuft rows all have pointed tips (in the lateral direction) and beveled outside edges at the top portion thereof. The shorter bristle tuft rows also have beveled outside edges. The shorter bristle tuft rows between the distal and intermediate rows have angled top surfaces in addition to the beveled outside edges.
