(EN) According to the practice of the present invention, a toothbrush with two distinct, flexible bristle groups, a more densely packed first bristle group adjacent the toe of the toothbrush and a less densely packed second bristle group further from the brush toe, each group containing at least one radius of curvature and the second grouping containing two subsets of bristle tufts, the first subset of bristle tufts angled toward the toe of the toothbrush and the other away therefrom, which combination of features provides enhanced conformity to the curvature of the teeth and enhanced cleaning thereof.
(FR) L'invention porte sur une brosse à dents dotée de deux groupes de poils flexibles distincts, un premier groupe de poils disposés de manière plus dense étant placé adjacent au manche de la brosse à dents et un second groupe de poils disposés de manière moins dense étant situé à une distance plus éloignée du manche de la brosse, chaque groupe contenant au moins un rayon d'inclinaison et le second groupe contenant deux sous-ensembles de touffes de poils, le premier sous-ensemble de touffes de poils étant situé en angle par rapport au manche de la brosse à dents et l'autre sous-ensemble situé plus éloigné, la combinaison de ces caractéristiques permettant une conformité améliorée par rapport à la courbure des dents et un meilleur brossage de ces dernières.
