A dispensing toothbrush includes a toothpaste reservoir chamber formed in a handle having a paste advancing piston disposed therein. The handle may be closed at one end by a floss dispenser. The handle is connected to a brush head and adapter assembly which includes a manual actuator which is disposed for sliding movement in the adapter to displace a plunger which reduces the volume of a chamber in the plunger to discharge paste into a feed tube. The suction plunger may be biased by a spring or include an elastic memory sufficient to restore the plunger to its original position whereby paste is drawn from the paste reservoir into the plunger chamber. A rubber cover is disposed over the actuator and is also sealingly engageable with a removable, vented brush cover. |
