ABSTRACT:
Disclosed is a fountain toothbrush and a hollow handle, which are connected together to dispense toothpaste from a reservoir in the handle to the bristles of the toothbrush. Within the handle is a flexible tube which is secured at one end of the handle to prevent rotation and secured to a rotatable knob at the other end of the handle for rotation. Extending from the handle and through the toothbrush to the bristles is a conduit for extruding toothpaste to the bristles when the knob is rotated to twist the flexible tube thereby dispensing paste from the reservoir. Also provided is a cover for the toothbrush, which includes a stopper for sealing the conduit in the toothbrush.
