Abstract: A double-ended toothbrush having two bristle portions, a major or larger, contoured bristle portion at one end and a minor or smaller wedge-shaped bristle portion at the other, both formed of parallel rows of bristles extending out perpendicularly from a base which is longer and narrower than most available toothbrushes. The larger brush head has four parallel rows of tufts (except at its end) which are shaped or contoured to conform to the natural contour of the teeth and gingivae, with the two outer rows forming a shallow concavity, the shape allowing the use of the natural back-and-forth brushing action. The smaller, interdental brush head is made of six tufts arranged in two parallel rows which are cut in a uni-bevel facing outwards to form a small wedge-shaped interdental brush.
