Paste carrying toothbrush
A toothbrush that uses air pump system, usually seen in high-end helmets wherein a push button inflates an air pouch to customize the fit around jaws. The pump action inflates the air pouch and forces the toothpaste out and into the header section, where it flows out through channels and is ready to use. The header section is replaceable when bristles get old. Toothpaste can be refilled too.
