A toothbrush (10) has a number of rotatable brush assemblies (18) mechanically linked so as to move together with a handle (16). Each rotatable brush assembly (18) includes a wheel (22), with radially projecting bristles (26), configured to rotate about an axis (24) which is roughly parallel to a plane of contact (20) with the teeth. The axis (24) of rotation is inclined relative to a primary direction of insertion (14) of the toothbrush (10), corresponding to an extensional direction (14) of the handle (16), by an angle of between about 15~ and about 75~, and preferably closer to 45~.
L'invention concerne une brosse à dents (10) qui comporte un certain nombre d'ensembles de brosses rotatives (18) reliés mécaniquement pour bouger ensemble, ainsi qu'une poignée (16). Chaque ensemble de brosses rotatives (18) comprend une roue (22), avec des poils saillants radialement (26), conçue pour tourner autour d'un axe (24) qui est approximativement parallèle à un plan de contact (20) avec les dents. L'axe de rotation (24) est incliné par rapport à une direction primaire d'insertion (14) de la brosse à dents (10), correspondant à une direction extensionnelle (14) de la poignée (16), d'un angle compris entre environ 15· et environ 75·, et, de préférence, avoisinant 45·.
