Oral care systems

1. An oral care system suitable for use in providing a beneficial effect to an oral cavity of a mammal, said system comprising,

a. an application tray or mouthpiece for directing a liquid effective for providing said beneficial effect to said oral cavity onto a plurality of surfaces of said oral cavity, said application tray or mouthpiece comprising:

a chamber for contacting said liquid with said plurality of surfaces, said chamber defined by front and rear inner walls and a base inner wall of said means for directing, said base wall extending between said front and rear inner walls, said front and rear inner walls comprising a plurality of openings,

a first manifold for containing a first portion of said liquid and providing said first portion to and from said chamber through said openings of said front inner wall,

a second manifold for containing a second portion of said liquid and providing said second portion to and from said chamber through said openings of said rear inner wall,

a first port for conveying said first portion of liquid to and from said first manifold,

a second port for conveying said second portion of liquid to and from said second manifold;

b. means for providing reciprocation of said liquid over said plurality of surfaces under conditions effective to provide said beneficial effect, said means of providing reciprocation of said liquid comprising at least one pump for alternately: (i) directing fluid into said chamber through said first manifold and out of said chamber through said second manifold, and (ii) directing fluid into said chamber through said second manifold and out of said chamber through said first manifold; and

c. means for providing said liquid to and from said application tray or mouthpiece and said means for providing reciprocation.

2. The system of claim 1 wherein said application tray or mouthpiece comprises a plurality of front lumens connected by said first manifold and a plurality of rear lumens connected by said second manifold.

3. The system of claim 1 wherein said application tray or mouthpiece comprises a top piece and a bottom piece for providing substantially simultaneous contact of a plurality of surfaces of both top and bottom sections of said oral cavity.

4. The system of claim 1 wherein said pump is a dual action piston pump.

5. The system of claim 1 wherein said at least one pump comprises a first pump to direct fluid from said means for providing reciprocation into said chamber and a second pump for providing vacuum to pull fluid out of said chamber.

6. The system of claim 1 further comprising a reservoir for containing said fluid.

7. The system of claim 1 wherein said means for providing reciprocation comprises a hand held device.

8. The system of claim 7 further comprising a base station into which the hand held means for providing reciprocation is inserted to dock.

9. An oral care system suitable for use in providing a beneficial effect to an oral cavity of a mammal, said system comprising:

a. a mouthpiece or application tray for directing a liquid effective for providing said beneficial effect to said oral cavity onto a plurality of surfaces of said oral cavity, said mouthpiece or application tray comprising:

a chamber for contacting said liquid with said plurality of surfaces, said chamber defined by front and rear inner walls and a base inner wall of said means for directing, said base wall extending between said front and rear inner walls, said front and rear inner walls comprising a plurality of openings,

a first manifold for containing a first portion of said liquid and providing said first portion to and from said chamber through said openings of said front inner wall,

a second manifold for containing a second portion of said liquid and providing said second portion to and from said chamber through said openings of said rear inner wall,

a first port for conveying said first portion of liquid to and from said first manifold, and

a second port for conveying said second portion of liquid to and from said second manifold;

b. a reservoir for containing said fluid;

c. at least one pump to simultaneously direct fluid from said reservoir to said mouthpiece or application tray and pull fluid from said mouthpiece or application tray to said reservoir;

d. means for providing said liquid to and from said reservoir and said mouthpiece or application tray;

wherein said fluid is alternately: (i) directed into said chamber through said first manifold and out of said chamber through said second manifold, and (ii) directed into said chamber through said second manifold and out of said chamber through said first manifold.
