Abstract
A unitarily molded toothbrush is provided including a head with bristles integrally molded therewith, the bristles being integrally anchored to a top surface of the head and having a polygonal cross-section defined by at least three faces, at least one of the faces gradually transitioning outward as a slope in an area near the head top surface to minimize breakage and deformation. Preferably the bristles have a triangular cross-section with slopes of two of the faces being different from one another.
