Abstract: A dental apparatus adapted for penetrating and cleaning the interstices and interproximal surfaces between the teeth, the surfaces at and below the gum margins, and the tooth-gum interfaces including the grooves and crevices thereof, is provided. In a preferred embodiment, a neck portion interconnects an elongated handle portion and a head portion, with the head portion being angled upwardly of the handle portion. A plurality of tufts of bristles are fixedly attached to the face of said head portion, said tufts of bristles having wedge means and conforming means to enable penetration into and cleaning of said interstices, surfaces and interfaces.A single row of a plurality of tufts of bristles, disposed substantially perpendicularly of said handle portion, has the free end of each of said plurality of tufts which are disposed at said end of said head portion beveled, said bevel sloping upwards from a vertex formed at said free end of the outermost bristle in each of said tufts.
