  • Silver-plated tooth brush
    Patent number: 4411041
    Abstract: Silver-plated tooth brush comprising the brush head and the handle, fixed together by a moveable connection to enable silver-plating to be done to the head only, and to make it interchangeable. The brush head, including the holes in which the tufts of the bristles are fitted, is entirely coated with a layer of silver whose bactericidal properties, when contacted with water, are transferred by the water to the bristles by the ions of silver possessed within the silver.
