A toothbrush comprising: an elongated tuft of bristles shaped and configured to enclose, at least partially, an area, thereby forming an elongated bristle tuft having a contoured interior shape surrounding the partially enclosed area, wherein the elongated tuft extends about the area such that the area is bound on more than one side by the elongated tuft; and at least one complementary-shaped tuft of bristles in the at least partially enclosed area enclosed by said elongated tuft, said at least one complementary-shaped tuft of bristles being shaped at least to fit within the partially enclosed area enclosed by said elongated tuft and to complement said contoured interior of said elongated bristle tuft; wherein: said elongated bristle tuft and said complementary-shaped bristle tuft extend from a substantially planar head surface of a toothbrush head; said elongated bristle tuft has a bristle profile presenting a cleaning surface angled to a first degree with respect to said toothbrush head surface; said complementary-shaped bristle tuft has a bristle profile presenting a cleaning surface angled to a second degree with respect to said toothbrush head surface, said second degree differing from said first degree said bristle profile of said elongated bristle tuft and said bristle profile of said complementary-shaped bristle tuft are substantially planar; wherein said bristle profile of said elongate bristle tuft extends in a first direction angled with respect to said toothbrush head surface; and said bristle profile of said complementary-shaped bristle tuft extends in a second direction angled with respect to said toothbrush head surface wherein said second direction is different from said first direction. an elongated tuft of bristles shaped and configured to enclose, at least partially, an area, thereby forming an elongated bristle tuft having a contoured interior shape surrounding the partially enclosed area, wherein the elongated tuft extends about the area such that the area is bound on more than one side by the elongated tuft; and at least one complementary-shaped tuft of bristles in the at least partially enclosed area enclosed by said elongated tuft, said at least one complementary-shaped tuft of bristles being shaped at least to fit within the partially enclosed area enclosed by said elongated tuft and to complement said contoured interior of said elongated bristle tuft; wherein: said elongated bristle tuft and said complementary-shaped bristle tuft extend from a substantially planar head surface of a toothbrush head; said elongated bristle tuft has a bristle profile presenting a cleaning surface angled to a first degree with respect to said toothbrush head surface; said complementary-shaped bristle tuft has a bristle profile presenting a cleaning surface angled to a second degree with respect to said toothbrush head surface, said second degree differing from said first degree said bristle profile of said elongated bristle tuft and said bristle profile of said complementary-shaped bristle tuft are substantially planar; wherein said bristle profile of said elongate bristle tuft extends in a first direction angled with respect to said toothbrush head surface; and said bristle profile of said complementary-shaped bristle tuft extends in a second direction angled with respect to said toothbrush head surface wherein said second direction is different from said first direction. said elongated bristle tuft and said complementary-shaped bristle tuft extend from a substantially planar head surface of a toothbrush head; said elongated bristle tuft has a bristle profile presenting a cleaning surface angled to a first degree with respect to said toothbrush head surface; said complementary-shaped bristle tuft has a bristle profile presenting a cleaning surface angled to a second degree with respect to said toothbrush head surface, said second degree differing from said first degree said bristle profile of said elongated bristle tuft and said bristle profile of said complementary-shaped bristle tuft are substantially planar; wherein said bristle profile of said elongate bristle tuft extends in a first direction angled with respect to said toothbrush head surface; and said bristle profile of said complementary-shaped bristle tuft extends in a second direction angled with respect to said toothbrush head surface wherein said second direction is different from said first direction.
