ABSTRACT:
A brush head for an electric toothbrush with a bristle carrier, in which bristles which are set in motion during the operation of the electric toothbrush, are anchored. The bristles are at least partly pointed filaments, which are arranged on the bristle carrier in such a way that, during the operation of the electric toothbrush, their tips cover at most a predetermined maximum path dmax. This advantageously succeeds in providing a toothbrush with an improved cleaning effect, in particular of the spaces between the teeth and the smallest structures on the tooth surface, while minimizing the mechanical loading, and consequently the wear, of the pointed filaments. The electric toothbrush has such a brush head, and a production method for such a brush head is shown.
