a plurality of teeth cleaning pads, the teeth cleaning pads comprising:
a first facial teeth cleaning pad coupled to the first facial wall; and
a first glossal teeth cleaning pad coupled to the first glossal wall so as to oppose the first facial teeth cleaning pad, the first facial teeth cleaning pad and the first glossal teeth cleaning pad being oriented such that an acute angle is formed therebetween;

a plurality of air bladders operably coupled to the teeth cleaning pads; and
an air-flow subsystem operably coupled to the air bladders;
wherein the first facial wall comprises a first facial wall portion a second facial wall portion, and a third facial wall portion, the first glossal wall comprises a first glossal wall portion, a second glossal wall portion and a third glossal wall portion, and the first channel floor comprises a first floor portion, a second floor portion, and a third floor portion;
wherein the plurality of air bladders comprises a first facial air bladder located adjacent the first facial wall portion, a second facial air bladder located adjacent the second facial wall portion, a third facial air bladder located adjacent the third facial wall portion, a first glossal air bladder located adjacent the first glossal wall portion, a second glossal air bladder located adjacent the second glossal wall portion, a third glossal air bladder located against the third glossal wall portion;
wherein the first facial teeth cleaning pad is coupled to the first facial air bladder, and the first glossal teeth cleaning pad is coupled to the first glossal air bladder;
wherein the plurality of teeth cleaning pads comprises a second facial teeth cleaning pad coupled to the second facial air bladder, a third facial teeth cleaning pad coupled to the third facial air bladder, a second glossal teeth cleaning pad coupled to the second glossal air bladder, and a third glossal teeth cleaning pad coupled to the third glossal air bladder; and
wherein each of the second facial teeth cleaning pad, the third facial teeth cleaning pad, the second glossal teeth cleaning pad, and the third glossal teeth cleaning pad is positioned at a third angle with respect to the first floor portion of the first support structure.

2. The device according to claim 1 , wherein the first channel floor comprises a first floor portion, a second floor portion, and a third floor portion, the first floor portion having a first width and the second and third floor portions having a second width, the first width being less than the second width.

3. The device according to claim 1 , wherein the first facial teeth cleaning pad is positioned perpendicular to the first channel floor, and the first glossal teeth cleaning pad is positioned at an oblique angle with respect to the first channel floor.

4. The device according to claim 1 , wherein the air-flow subsystem comprises:
a first valve operably coupled between the first facial air bladder and the air pump;
a second valve operably coupled between the first glossal air bladder and the air pump;
a third valve operably coupled between the second facial air bladder and the air pump and between the third glossal air bladder and the air pump; and
a fourth valve operably coupled between the third facial air bladder and the air pump and between the second glossal air bladder and the air pump.

5. The device according to claim 1 , wherein the air-flow subsystem comprises:
a first transfer pump operably coupled between the first facial air bladder and the first glossal air bladder; and
a second transfer pump operably coupled between (1) the second facial air bladder and the third glossal air bladder and (2) the third facial air bladder and the second glossal air bladder.

6. The device according to claim 1 , wherein:
the plurality of air bladders further comprises a first floor air bladder located adjacent the second floor portion and a second floor air bladder located adjacent the third floor portion; and
the plurality of teeth cleaning pads comprises a first floor teeth cleaning pad coupled to the first floor air bladder and a second floor teeth cleaning pad coupled to the second floor air bladder.

7. The device according to claim 6 , further comprising:
a second support structure comprising a second dentature channel configured to receive at least a second portion of the dentature of the user, the second dentature channel defined by a second channel floor, a second facial wall, and a second glossal wall, wherein the second channel floor comprises a fourth floor portion and a fifth floor portion;
the plurality of air bladders further comprises a third floor air bladder located adjacent the fourth floor portion and a fourth floor air bladder located adjacent the fifth floor portion; and
the plurality of teeth cleaning pads comprises a third floor teeth cleaning pad coupled to the fourth floor air bladder and a fourth floor teeth cleaning pad coupled to the fifth floor air bladder.

8. The device according to claim 7 , wherein the at least on valve comprises:
a fifth valve operably coupled between the first and second floor air bladders and the air pump; and
a sixth valve operably coupled between the third and fourth air bladders and the air pump.

9. The device according to claim 7 , further comprising:
a third transfer pump operably coupled between (1) the first and second floor air bladders and (2) the third and fourth air bladder.

10. The device according to claim 1 , wherein each teeth cleaning pad is integrally formed with one of the air bladders.

11. The device according to claim 1 , wherein the air-flow subsystem comprises a pressure release valve operably coupled to the air bladders.

12. The device according to claim 1 , wherein each air bladder is formed of one of a silicon rubber or a polyurethane.

13. The device according to claim 1 , wherein each air bladder has a Shore hardness between and including 15-30 A.
