Abstract

A dental tool for personal oral hygiene includes a pen barrel shaped holder which carries a curved metal pick. The pick includes an arcuate zone ending at a tapered tip. A cap selectively covers the pick when the tool is not in use to simulate a writing implement. Opposite the tip, the pick includes a stem which is seated in the holder. The pick is formed of a stainless resilient metal alloy having a diameter in the order of one millimeter. The arcuate zone is employed to dislodge food or debris from pockets or interproximal spaces at both the mesial and distal areas of the oral cavity with the tip functioning as a probe. The convex surface of the arcuate zone is employed as a burnishing implement for the removal of soft plaque.

Claims

1. A dental tool for personal oral hygiene comprising a pick, the pick having a stem and an arcuate zone projecting from the stem and terminating at a tip, the tip extending along a plane substantially perpendicular to the axis of the stem and projecting beyond the stem axis a distance up to but not significantly greater than three millimeters, the pick being formed of a resilient material, the material having a diameter in the order of one millimeter at the arcuate zone and tapering to a smaller diameter at the tip, the stem diameter being larger than the material diameter at the arcuate zone, the arcuate zone being anatomically configured to be accommodatingly received around curved tooth surfaces and including a longitudinal span of between substantially ten to fifteen millimeters, the tip passing between interproximal spaces formed between adjacent teeth in the user'"'"'s mouth with the pick contoured to avoid interference with adjacent teeth to thereby efficaciously remove materials lodged in such interproximal spaces, the tool further including an elongate cylindrical holder, means securing the pick at one end of the holder and a cap, the cap selectively covering the pick when not in use, the holder and the cap being configured in simulation of a writing implement whereby the tool may be inconspicuously carried about.

2. A dental tool for personal oral hygiene constructed in accordance with claim 1 further including a carrier, the means securing the pick to the holder including means mounting the stem to the carrier and means selectively securing the carrier to the holder, the pick and the carrier comprising a replaceable unit.

3. A method of removing material lodged in a user'"'"'s mouth with a personal oral hygiene tool constructed in accordance with claim 1, said method comprising the steps of:

(a) ascertaining the location of the lodged material,

(b) removing the cap to expose the pick,

(c) grasping the holder and rotating the holder to orient the tip and the arcuate zone adjacent the tip toward the lodged material,

(d) removing the lodged material by applying lateral pressure to gently force the tip against the lodged material.

4. A method in accordance with claim 3 wherein the lodged material is located at a distal area of the user'"'"'s mouth, the method further including the step of orienting the curvature of the arcuate zone to be coincident with a curved surface of the tooth immediately preceding the located material to avoid interference between the pick and the preceding tooth when the tip is urged laterally against the material.

5. A method in accordance with claim 3 further including the step of placing the removed cap over the opposite end of the holder before removing the lodged material.
