  • Patent number: 5382106
    Abstract: An improved toothbrush with a teeth cleansing substance dispensing system is provided, which consists of a mechanism in cooperation with a compartment in an enlarged handle, which will dispense some teeth cleansing substance through a channel in a neck and head and out through at least one lateral passageway into bristle groups, so that the bristle groups can clean teeth. An apparatus is also in cooperation with the channel in the head and neck for sealing the at least one lateral passageway, when not in use. This stops the flow of the teeth cleansing substance and prevents germs, bacteria, water and other foreign elements from contaminating the teeth cleansing substance left in the channel and the compartment.
