Abstract

La présente invention concerne une tête de brosse à dents comprenant : une zone centrale comprenant un corps élastique en caoutchouc ; et une zone revêtue, qui est formée autour de la circonférence de la zone centrale et qui comprend une résine qui est plus dure que le corps élastique en caoutchouc, une pointe à partir de laquelle la zone centrale est découverte étant formée dans une partie d'extrémité de celle-ci. Ainsi, étant donné que la pointe est formée dans la partie d'extrémité qui entre en contact avec la gencive de telle sorte que le corps élastique en caoutchouc soit exposé à partir de celle-ci, l'invention présente l'avantage de procurer un massage souple des gencives pendant le brossage des dents.
