The interproximal dental tool includes a compact, ergonomically designed housing which is gripped by a dental practitioner during use and a blade extending from and structurally supported by the housing which includes serrations for cutting or abrasive materials for sanding unwanted material. ## Claims ### Claim 1 An interproximal dental tool comprising: at least one blade; and a substantially u-shaped thermoplastic housing secured to said at least one blade, said substantially u-shaped thermoplastic housing including a body having an outer edge that includes spaced apart first and second grip ends that are angled so as to at least partially diverge away from each other proximate terminal ends thereof, said outer edge and said first and second grip ends including concave portions, a terminal inner edge extending between said first and second grip ends, said outer edge being thicker than the terminal inner edge, and opposing side walls which extend from the outer edge to the terminal inner edge; whereby said at least one blade includes an exposed portion including at least one of serrations or abrasive material for detaching unwanted material from teeth. ### Claim 2 (depends on 1) The interproximal dental tool of claim 1, wherein said first and second grip ends include ribs for enhanced gripping. ### Claim 3 (depends on 1) The interproximal dental tool of claim 1, wherein the body is thicker along the first and second grip ends than at the center. ### Claim 4 (depends on 1) The interproximal dental tool of claim 1, wherein said body includes at least one through-hole for receiving a tether. ### Claim 5 (depends on 1) The interproximal dental tool of claim 1, wherein said blade is permanently fixed to said housing. ### Claim 6 (depends on 1) The interproximal dental tool of claim 1, wherein said side walls taper downwardly along at least a portion thereof in the direction of the terminal edge. ### Claim 7 An interproximal dental tool comprising: at least one blade; and a substantially u-shaped thermoplastic housing secured to said at least one blade, said substantially u-shaped thermoplastic housing including a body having an outer edge and spaced apart first and second grip ends that are angled so as to at least partially diverge away from each other proximate terminal ends thereof, a terminal inner edge extending between said first and second grip ends, said outer edge being thicker than the terminal inner edge, and opposing side walls which extend from the outer edge to the terminal inner edge; whereby said at least one blade includes an exposed portion including at least one of serrations or abrasive material for detaching unwanted material from teeth, wherein the body is concaved along at least one of side walls between the first and second grip ends. ### Claim 8 An interproximal dental tool comprising: at least one blade; and a substantially u-shaped thermoplastic housing secured to said at least one blade, said substantially u-shaped thermoplastic housing including a body having spaced apart first and second grip ends, a terminal inner edge extending between said first and second grip ends, an outer edge which is thicker than the terminal inner edge and having a portion that is thinner than said first and second grip ends, said outer edge and said first and second grip ends including concave portions, opposing side walls which extend from the outer edge to the terminal edge and taper in the direction of the terminal edge, and at least one hole disposed in the body for receiving a tether; whereby said at least one blade includes an exposed portion including at least one of serrations or abrasive material for detaching unwanted material from teeth. ### Claim 9 (depends on 8) The interproximal dental tool of claim 8, wherein said first and second grip ends of the housing include enhanced gripping means along said outer edge. ### Claim 10 (depends on 8) The interproximal dental tool of claim 8, wherein said enhanced gripping means along said outer edge are located proximate the first and second grip ends. ### Claim 11 (depends on 10) The interproximal dental tool of claim 10, wherein said enhanced gripping means are in the form of protrusions projecting away from said outer edge. ### Claim 12 (depends on 8) The interproximal dental tool of claim 8, wherein the body is thicker along the first and second grip ends than at the center. ### Claim 13 (depends on 8) The interproximal dental tool of claim 8, wherein the body is at least partially concaved along the side walls between the first and second grip ends. ### Claim 14 (depends on 8) The interproximal dental tool of claim 8, wherein said blade is permanently fixed to said housing. ### Claim 15 (depends on 8) The interproximal dental tool of claim 8, wherein the distance from said terminal edge to said leading edge along a center point defined by said first and second ends is no more than about 0.4 inches.
