The present invention relates to an electromotion toothbrush, and more particularly to an electromotion toothbrush which easily converts rotational direction thereof by simple manipulation of a switching circuit and easily removes foreign substances in gaps between teeth. For the purpose, the present invention comprises: a grip which can accommodate a driving motor for generating rotational force, a power supply for supplying power to the driving motor and a decelerator connected to the driving motor for decelerating the rotational speed of the output shaft of the driving motor; a direction conversion switch provided between the power supply and the driving motor for easily converting the rotational direction of the driving motor into a positive or reverse direction; a rotating toothbrush bar consisting of a rotating rod installed to the decelerator and a removable bristle part which is positioned on the rotating rod and on which toothbrush bristles are planted; and a removable protective stand installed at one side of the top of the grip parallel to the rotating toothbrush bar. The bristle part has longer bristles on the upper part, the middle and the lower part thereof, than that provided to the other parts.
