Abstract
A toothbrush head having a bristle carrier, and bristles held in bristle holders, the bristle holders being connected to the bristle carrier by resilient connectors which cause the holders to move resiliently as brushing pressure is applied to the bristles and also cause the bristle holders to rotate. A suitable form of connector follows a conical surface between the bristle holder and bristle carrier.
