Abstract

A method for producing a brush head for a toothbrush head is disclosed. The method includes the steps of providing a bristle carrier; providing cleaning elements having first ends which will not be embedded in the bristle carrier and second ends which will be embedded in the bristle carrier, wherein the cleaning elements are selected from at least two different types of cleaning elements or at least two distinctive cleaning elements of the same type; placing the first ends of the cleaning elements in the bristle carrier in a carrier part for holding; and supplying different amounts of heat to the second ends in the bristle carrier by reflecting the heat supplied partially from the carrier part and/or absorbing the heat supplied partially by the carrier part resulting in the second end being molten.
