Abstract

L'invention concerne une brosse à dents. La brosse à dents peut comprendre une tête de brosse ayant une première brosse et une seconde brosse. Chacune de la première brosse et de la seconde brosse peut comprendre des poils s'étendant radialement à partir de premières extrémités de la première brosse et de la seconde brosse. La première brosse et la seconde brosse peuvent tourner dans des directions opposées le long d'axes de rotation parallèles à un axe longitudinal de la brosse à dents pour brosser les gencives d'un utilisateur et aider à mettre en oeuvre un procédé de brossage par rotation.
