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.
Claims15
An oral care brush comprising:
- an elongated handle having opposite first and second ends;
- and
- a brush head having a closed first end and an opposite open second end, at least one-peripheral face with a plurality of bristles extending orthogonally therefrom, and a hollow interior for releasably receiving said first end of said handle through said open second end of said head, with the head being composed of a material which is substantially shape-retaining but which is soft and resilient,
- said first end of said handle being structured such that upon receipt thereof in said hollow interior of said brush head, it cooperates with an inner surface and said closed first end of said head to entrap a volume of air in said hollow interior of said head;
- whereby when said oral care brush is used for brushing of teeth or gums or both, said entrapped volume of air acts as an air cushion and moderates relative movement of said handle and said head, such that in combination with said soft and resilient material composing said head, a user obtains effective massaging and stimulation of the gums in conjunction with effective brushing of the teeth without suffering stress imposed upon the gums.
