  • Patent number: 5944519
    Abstract: A device for oral cleaning consists of an elongate handle carrying a resilient pad, for example of polyester foam, with flock adhering directly to its surface. Preferably the pad surrounds an underlying support portion of the handle so that this does not contact the interior of the mouth in use. The handle support portion may have a series of projections to enhance the cleaning action. The pad may be pre-impregnated with an oral cleaning agent.
