A toothbrush is disclosed including a head (201) with a bristle mounting surface (209) having a center section (217) within which an array of bundles of bristles (207) is mounted, and a pair of bristle supports (218,219) located at either end of the center section which are effective to resist bending of the bristles within the center section in the longitudinal direction in response to brushing motion so that the tips of such bristles are maintained in contact with the teeth.

L'invention concerne une brosse à dents comprenant une tête (201) dotée d'une surface de montage (209) de soies, cette surface comportant une section centrale (217) dans laquelle un groupe de faisceaux de soies (207) est monté, ainsi qu'une paire de supports de soies (218, 219) situés à l'une ou l'autre extrémité de la section centrale. Ces supports agissent efficacement pour empêcher la flexion des soies dans la section centrale, dans le sens longitudinal, en réponse à des mouvements de brossage, de façon que les extrémités de ces soies restent en contact avec les dents.
