Claim:
A process for producing a toothbrush, comprising: producing at least one carrier element having a top surface, a rear surface and a plurality of cutouts running between the top surface and the rear surface, the top surface and the rear surface each having a non-planar three-dimensional configuration; guiding clusters of bristle filaments through the cutouts in the at least one carrier element; connecting the clusters of bristle filaments to the rear surface of the at least one carrier element by melting the rear ends of the bristle filaments using a heating die, with the result that a bristle coating at least partially covering the rear surface is formed on the rear surface of the at least one carrier element; and connecting the at least one carrier element holding the clusters of the bristle filaments and the bristle coating to a head part of the toothbrush such that the top surface of the at least one carrier element defines a front surface of the head part, wherein the at least one carrier element is produced by two-component injection molding from a hard material and a soft material, then provided with the clusters of bristle filaments and connected to the head part.
