The invention relates to an electric toothbrush comprising a handle and a head movable with respect to said handle and provided with a rotating working element having at least one brush, said working element located out of the geometric axis of said handle, said electric toothbrush having in addition an electric motor for driving the working element in a rotary movement in a clockwise or counterclockwise direction and having a motor rotation direction switch, coupled functionally with the head and the handle, characterized in that the head (2), (15) is joined with the handle (1) by a rotating coupling, and the working element (3), (16) is mounted in the head (2), (15) and located out of the rotation axis of the head (2), (15) with respect to the handle (1), wherein the head (2), (15) and the handle (1) are coupled with resilient technical means (10), (19), enabling - after exertion of the torque to the head (2) - to rotate the head (2), (15) with respect to the handle (1) into the left or the right position, in which position the motor rotation direction switch turns on the motor (5), (25) in the clockwise or counterclockwise rotation direction and after release of said torque, said resilient technical means (10), (19) enable to maintain the head (2), (15) in a standby position relative to the handle (1), in which position the motor rotation direction switch coupled with the head (2), (15) and the handle (1) turns off the motor (5), (25).L'invention concerne une brosse à dents électrique composée d'une poignée et d'une tête mobile par rapport à ladite poignée, et comprenant également un élément rotatif fonctionnel équipé d'au moins une brosse, ledit élément fonctionnel étant situé hors de l'axe géométrique de ladite poignée. Ladite brosse à dents électrique possède également un moteur électrique permettant d'assurer la rotation de l'élément fonctionnel dans le sens des aiguilles d'une montre ou dans le sens inverse des aiguilles d'une montre et intégrant un commutat
