Abstract

A brush head section for an oral care device is provided. The brush section includes an insert being made from a first thermoplastic material by injection-molding, at least one oral cleaning element and a cleaning element carrier consisting of a second thermoplastic material or a second thermoplastic mixture. The insert and the at least one cleaning element are partially embedded into the cleaning element carrier by over-molding and the cleaning element carrier at least partly engages behind the insert. The hardness of the second thermoplastic material is less than the hardness of the first thermoplastic material.
