Abstract

The invention concerns a toothbrush having a handle and a brush head wherein the brush head comprises non-circular cross section filaments. The filaments have a trilocular, tetralocular, trilobular, rectangular or hexagonal cross section. These toothbrushes offer a much better cleaning efficiency c.q. better plaque removal from the tooth surface.
