Methods for providing beneficial effects to the oral cavity
A device for providing a beneficial effect to an oral cavity of a mammal, the device providing: a liquid for contacting a plurality of surfaces of the oral cavity, wherein the liquid is effective for providing the beneficial effect to the oral cavity, and reciprocation of the liquid over the plurality of surfaces of the oral cavity under conditions effective to provide the beneficial effect.
1. An oral care system comprising:
a) an application tray or mouthpiece comprising:
i) a chamber for contacting liquid with a plurality of surfaces of teeth therein, said chamber defined by front and rear inner walls and a base inner wall, said base wall extending between said front and rear inner walls, said front and rear inner walls comprising a plurality of openings,
ii) a first manifold for providing fluid to and from said chamber through said openings of said front inner wall,
iii) a second manifold for providing fluid to and from said chamber through said openings of said rear inner wall,
iv) a first port for conveying liquid to and from said first manifold,
b) at least one pump for alternately and repeatedly over a period of time: (i) directing a liquid effective for removing biofilm from said plurality of surfaces of teeth into said chamber through said first manifold and out of said chamber through said second manifold, and (ii) directing said liquid into said chamber through said second manifold and out of said chamber through said first manifold; and
c) collection device for collecting biofilm removed from said plurality of surfaces of the teeth by said liquid.
2. The system of claim 1 wherein said biofilm comprises plaque.
3. The system of claim 1 wherein said liquid comprises a vehicle and an abrasive.
4. The system of claim 3 wherein said liquid comprises water.
5. The system of claim 4 wherein said vehicle further comprises additives selected from the group consisting of shear thinning agents, thickening agents, and gelling agents.
6. The system of claim 3 wherein said abrasive is selected from the group consisting of silica, sodium bicarbonate, alumina, apatites, and bioglass.
7. The system of claim 1 wherein said collection device comprises a reservoir for collecting said biofilm.
