A toothbrush assembly has two main sections, a toothbrush head that
incorporates toothbrush bristles and toothpaste holder. The toothbrush
head has a bristle end and a shaft with an enclosed channel connecting
the bristle end to a threaded end. A flexible tube extends from an
opening in the channel to near the top of bristles. The threaded end
mates to the chamber. The chamber is coupled to a plunger assembly having
a plunger head that seals against the sides of the chamber. The plunger
head pulls a vacuum on the chamber when moved laterally in a first
direction and pressurizes the chamber when moved laterally in a second
direction. A toothpaste tube is threaded into the threaded end of the
chamber and toothpaste is extracted from the toothpaste tube into the
chamber or delivered from the chamber to the bristles. A universal
adapter is used for non-compatible toothpaste tubes.
