The invention relates to an integral toothbrush having a similar shape to that of a mouth guard, which is designed to clean all of the teeth in a simple and simultaneous manner with minimum effort by the user. The integral toothbrush comprises an upper part and a lower part which are both in the shape of a U and include a channel for receiving the teeth. In addition, both of said parts are connected to a central part containing a set of gears and axles. According to the invention, the actuation of a first axle transmits a movement to the rest of the axles and gears, resulting in the movement of brush systems in the form of rows of transversely intersecting bristles disposed in the aforementioned channels in each of the upper and lower parts, thereby cleaning all of the teeth.
