ABSTRACT:
A toothbrush has a body, and a brush member connected to the body, the brush member including three brushes which are arranged at an angle relative to one another so as to provide two side brushes and one intermediate brush extending between the side brushes and to form an elongated passage between the brushes, adapted to receive teeth so that the brushes can contact the teeth from an inner side, from an outer side, and from a biting surface.
