Abstract

Abstract A dental implement is provided for removing stains and plaques from the teeth, and which may also be used as a gum stimulator. The implement is in the form of an elongated handle which may, for example, have the configuration of any one of the standard types of tooth brush handles. The handles may, for example, have a round, square, triangular or other cross-section shape, and it may be made of plastic or other suitable material. A tip is mounted on one end of the handle which is made of hardened rubber, plastic, or other appropriate material, and which has embedded in it an abrasive material such as a carborundum particles, pumice, or the like. The tip may also contain fluoride compounds, if desired, to aid in the resistance of the teeth to decay. It also may contain an appropriate flavoring to make the operation more enjoyable to the user. The other end of the handle is shaped to have a pick and hoe configuration to aid in the removal of plaques from the surface of and between the teeth. These ends may be offered as individual units rather than a double-ended instrument.
