Abstract
A toothbrush formed of a handle, a neck and a bristle head. In order to allow the bristle head to move out of the way in the event of excessive brushing pressure being applied during toothbrushing, an elastic segment is provided between the handle and the bristle head. Injury to the gums, damage to the teeth and possibly to the tooth-holding means can be averted by the elastic flexure of the bristle head. The elastic segment is formed by one or more clearances, slots or slits at least partially filled with elastic polymeric/copolymeric plastic material.
