Abstract: The invention relates to a method for producing a bristle, especially for a toothbrush. A filament thread is cooled following extrusion, re-heated and stretched, and optionally heated under stress. According to the invention, the filament thread is heated without any stress or with barely any stress. This allows for additional annealing which considerably improves the wear properties of the bristle in particular.

Abstract: A toothbrush head has a tooth cleaning element extending from the head. The head is divided into at least two portions which can be moved independent of each other. The tooth cleaning element is rotatable relative to that portion of the head from which it extends.
