Abstract

A teeth-cleaning device includes a rod-shaped, small diameter strand about which is surrounded a softer, floss-type material. The rod-shaped material is of sufficient stiffness to allow it to be used to remove food particles lodged between teeth, but sufficiently flexible to allow the invention to be bent to conform to the contours of the teeth for removing plaque. The material is also resilient, i.e., non-deformable, so that it returns to its original shape once it is removed from between the teeth for ease of use.

Claims

1. A dental probe comprising:

an unsupported thin core strand having a generally uniform cross-section of a material which is stiff and flexible but returns to substantially its original shape when not stressed; and

an outer sheath surrounding said core strand made of a material suitable for engaging teeth and gums.

2. A dental probe, as in claim 1, wherein the core strand is made of narrow gauge spring steel.

3. A dental probe as in claim 2 wherein said sheath is made of floss.

4. A dental probe as in claim 3 wherein said sheath comprises a thin thread of floss wrapped around said strand.

5. A dental probe as in claim 3 wherein said sheath is extruded on said strand.

6. A dental probe as in claim 3 wherein said sheath is sprayed on said strand.

7. A dental probe as in claim 3 wherein said strand fits within a floss bag.

8. A method of manufacturing a dental probe comprising the step of surrounding an unsupported thin, central rod having a generally uniform cross-section of a material which has the characteristics of being stiff and resilient but returns to substantially its original shape when not stressed, with an outer surface of floss.
