DENTAL FLOSSER

1 . A dental flosser for delivering to a mouth a moisture activated composition including a flavor agent, the dental flosser comprising:

a base portion forming a handle and terminating at a distal head portion;

a pair of spaced apart arms extending from the head portion, each of the spaced apart arms having a proximal first end adjoining the head portion and a distal second end;

a length of dental floss extending between the distal second ends of the arms,

wherein a surface of at least one arm of the pair of arms defines a cavity between the first end and the second end and extending into the thickness of the arm forming a well for accommodating the composition, and

wherein the width of the cavity in a plane parallel to the surface of the at least one arm is substantially the same or greater than the width of the bottom of the cavity.

2 . The dental flosser as recited in claim 1 , wherein the cavity has a depth less than the thickness of the arm.

3 . The dental flosser as recited in claim 1 , wherein each of the pair of spaced apart arms defines at least one cavity.

4 . The dental flosser as recited in claim 1 , wherein the cavity has width of about 2.75 mm wide, a depth of about 1.00 mm, and a length of about 5.77 mm.

5 . The dental flosser as recited in claim 1 , wherein the cavity has a central longitudinal axis and a slot in the bottom of the cavity extending along the central longitudinal axis of the cavity, the slot having a length less than the respective dimension of the cavity along the central longitudinal axis corresponding to the cavity length, the cavity length being greater than a respective dimension of the slot.

6 . The dental flosser as recited in claim 5 , wherein the slot has a depth of about 0.41 mm, a width of about 1.00 mm, and a length of about 4.03 mm.

7 . A system of oral care comprising:

a moisture activated composition comprising a flavor agent;

a dental flosser comprising

a base portion forming a handle and terminating at a distal head portion,

a pair of spaced apart arms extending from the head portion, each of the spaced apart arms having a proximal first end adjoining the head portion and a distal second end, a surface of at least one arm of the pair of arms defining between the first end and the second end a cavity having a width and forming a well for receiving the composition, the width of the cavity in a plane parallel to the surface of the at least one arm substantially the same or greater than the width of the bottom of the cavity; and

a length of dental floss extending between the distal second ends of the arms.

8 . The oral care system as recited in claim 7 , wherein the composition comprises materials selected from the group consisting of a flavor agent, an antimicrobial agent, a cleansing agent, a breath freshener, a mineralizing agent, a remineralizing agent, a therapeutic agent and combinations thereof.

9 . The oral care system as recited in claim 7 , wherein the cavity is sized to accommodate from about 5 mm 3 to about 15 mm 3 of the composition.

10 . The oral care system as recited in claim 7 , wherein the cavity has a depth less than the thickness of the arm.

11 . The oral care system as recited in claim 7 , wherein the cavity has width of about 2.75 mm wide, a depth of about 1.00 mm, and a length of about 5.77 mm.

12 . The oral care system as recited in claim 7 , wherein each of the pair of spaced apart arms defines at least one cavity.

13 . The oral care system as recited in claim 7 , wherein the cavity has a central longitudinal axis and a slot in the bottom of the cavity extending along the central longitudinal axis of the cavity, the slot having a length less than the respective dimension of the cavity along the central longitudinal axis corresponding to the cavity length, the cavity length being greater than a respective dimension of the slot.

14 . The oral care system as recited in claim 13 , wherein the slot has a depth of about 0.41 mm, a width of about 1.00 mm, and a length of about 4.03 mm.

15 . A method of making a dental flosser, the method comprising the steps of:

providing a flosser comprising

a base portion forming a handle and terminating at a distal head portion,

a pair of spaced apart arms extending from the head portion, each of the spaced apart arms having a proximal first end adjoining the head portion and a distal second end, and

a length of dental floss extending between the distal second ends of the arms,

wherein a surface of at least one arm of the pair of arms defines at least one cavity between the first end and the second end forming a well, and

wherein the width of the cavity in a plane parallel to the surface of the at least one arm is substantially the same or greater than the width of the bottom of the cavity;

providing a liquid bath of a composition comprising a flavor agent;

providing a base comprising a post extending from the base;

positioning a flosser over the bath;

advancing the base from a first position where the base is submerged in the bath to a second position such that the post extends vertically from the bath and registers with the cavity for delivery of flavor agent to the well; and

retracting the base to the first position after the composition has cooled to a temperature at which the composition begins to solidify and bond to the walls of the cavity such that the composition is deposited in the well.

16 . The method of making a dental flosser as recited in claim 15 , wherein the distal end of the post is planar and has an area smaller than an area of the cavity defined in a plane at the surface of the arm.

17 . The method of making a dental flosser as recited in claim 15 , wherein the post is positioned centrally in the cavity.
