Dental floss provided in the form of a continuous loop includes at least one tab positioned on the loop. The at least one tab provides a gripping feature for the continuous loop of floss material. A separate pick device can be configured to receive the continuous loop of floss material with the at least one tab positioned thereon. A cutout portion of the pick device provides the usable area for the floss once positioned in the holder. The pick device is configured to receive the continuous loop of dental floss material to assist in the use of the dental.

This disclosure proposes a technique for finding and treating areas of tooth decay primarily below the gum line using protuberances provided in a length of modified dental floss. The length of modified dental floss is provided with protuberances which can be used to detect areas of tooth decay by the roughness and sensitivity felt as the length of modified dental floss glides over the area of tooth decay. Specially designed posts are used to anchor the ends of the length of modified dental floss in order to be able to apply greater force during flossing, and free up fingers that would normally have the dental floss wrapped around them, to guide the floss to the right locations for flossing.

Embodiments of a floss strip and methods of using the same are disclosed herein. The floss strip can include a flossing filament. The flossing filament can have a first end and a second end. The flossing strip can include a first anchor coupled to the flossing filament at the first end of the flossing filament. The flossing strip can include a second anchor coupled to the flossing filament at the second end of the flossing filament. The flossing filament can couple the first and second anchors. The flossing strip can include a tensioning member attached to the flossing filament at an intermediate location between the first anchor and the second anchor.

Provided is a dental floss that keeps cleaning performance thereof on one hand, and that is easy to handle because of a high rigid portion thereof on the other hand. Dental floss includes: a floss part that is formed by twisting a plurality of filaments together but not tying up the filaments; and tied-up parts that are provided continuously with the floss part, and are formed by tying up the plurality of the filaments, wherein each of the tied-up parts is formed in such a manner that filaments are covered with a contour part in a cross section thereof.

A bristled dental floss is provided for effectively removing plaque, tartar, food particles and the like from between a user's teeth. The bristled dental floss includes an elongated, flexible floss core. A plurality of floss bristles extends from the floss core. At least one elongated bristle group is formed by the plurality of floss bristles. An undulating pattern is formed by the plurality of floss bristles in each bristle group. In typical use, the bristled dental floss may be inserted between the teeth of a user and moved in a back-and-forth motion. The bristle groups effectively remove plaque, tartar, food particles and the like from between the user's teeth, particularly in hard-to-reach recessed areas between the teeth.

A ridged dental floss that includes a flexible dental floss string of a polymeric material that includes multiple sections of ridges, wherein a first section includes a tightly spaced series of spherical ridges each of an elastic polymeric material and directly coupled to opposing sides of the dental floss string to define a diameter and a second section adjacent to the first section includes a tightly spaced series of spherical ridges each of an elastic polymeric material and directly coupled to opposing sides of the dental floss string to define a diameter, wherein the diameters of each of the tightly spaced series of spherical ridges in the second section are greater than the diameters of each of the tightly spaced series of spherical ridges in the first section.
