Abstract:

The present invention provides a dental appliance for cleansing the gingival one third areas of the teeth, the sulcular regions and the embrasure regions. The dental appliance of the present invention is in the form of a tooth brush having a brush head portion a handle portion and a neck portion. A plurality of tufts of bristles are connected to the brush head portion, preferably in a single row. The tufts form an undulating brushing surface having a plurality of alternating convex and concave regions. The convex regions are configured to coincide with portions of the free gingival margin adjacent to the facial surfaces of selected teeth and the concave regions are configured to coincide with the interproximal margins between the teeth selected in configuring the convex regions. As a result of the coincidence, the aforementioned areas of the teeth and gingivae can be efficiently cleaned. In order to permit easy manipulation of the appliance within the oral cavity, the brush head portion is cylindrical.
