CA 2462822

A preferably non-electric, non-mechanically actuated toothbrush is provided having a generally U-shaped appearance with a rotary brush (14, 16) located, during use, on each side of a tooth to be cleaned. The brushes are configured to rotate about an axis (24, 26) which is parallel to the long axis of the tooth to be cleaned, and essentially perpendicular to the buccal and lingual gum line, of the user. The brushes are preferably held in contact with the teeth and gum tissue by a resilient section of the toothbrush. In this fashion, a pushing and pulling motion during brushing results in a rotational motion of the brushes. An improved method for cleansing teeth, cleaning the opening to the gingival crevice area, and stimulation of the gingival tissue is provided.

L'invention concerne une brosse à dents actionnée, de préférence, de manière non électrique et non mécanique. Cette brosse à dents présente une forme générale de U et deux brosses rotatives (14, 16) situées, pendant l'utilisation, sur chaque côté d'une dent à nettoyer. Les brosses sont conçues de manière à tourner autour d'un axe (24, 26) parallèle au long axe de la dent à nettoyer de l'utilisateur et généralement perpendiculaire à la ligne du bord gingival buccal et lingual. Les brosses sont, de préférence, maintenues en contact avec la dent et le tissu gingival, par une section élastique de la brosse à dents. De cette manière, un mouvement de poussée et de traction pendant le brossage permet d'obtenir un mouvement rotatif des brosses. L'invention concerne également un procédé amélioré permettant de nettoyer les dents et l'ouverture de la zone de la crevasse gingivale et de stimuler le tissu gingival.
