[Solution] Cette brosse à dents est pourvue d'une partie de préhension au niveau de la partie inférieure d'un support pour poils et présente une partie brosse conçue à partir d'une pluralité de touffes de brosse tuftées dans le support pour poils. Au moins une saillie en forme de crête (saillie de traction) est formée sur la pointe d'une partie de traction de la partie brosse. Lorsque l'on regarde dans la direction suivant les côtés courts, la saillie (saillie de traction) est formée de façon à présenter un angle de sommet aigu ou et une ligne de bord linéaire ou incurvée descendant vers les extrémités latérales correspondantes. Lorsque l'on regarde dans la direction suivant les côtés longs, la saillie (saillie de traction) est formée de façon à présenter un angle de sommet aigu et comprend un bord latéral de traction présentant une ligne de bord sensiblement verticale et un bord latéral de partie inférieure présentant une ligne de bord linéaire ou incurvée descendant vers la partie inférieure.
