  • Patent number: 6671919
    Abstract: A oral care brush device is described for use primarily for massaging and stimulation of sensitive gums and teeth. The brush head is hollow but closed at one end, and is made of a shape-retaining but soft and resilient material. One end of the brush handle is inserted into the hollow handle and is configured to substantially seal the open end of the head and trap air inside, the trapped air providing an air cushion effect. The air cushion effect and the soft head allow use of the device for effective and thorough cleaning, massage and stimulation of the gums and teeth notwithstanding the user's tooth or gum sensitivity.
