An oral hygiene system includes a mouthpiece having an outer portion and an inner portion configured to receive at least a portion of a user's dental and gum structures, a plurality of filaments disposed within the inner portion of the mouthpiece, a water pressure irrigator configured to be selectively coupled to the outer portion of the mouthpiece and to deliver fluid to the inner portion of the mouthpiece, and a fluid reservoir in fluid communication with the water pressure irrigator and configured to deliver the fluid thereto, wherein the system is configured to generate ultrasound/ultrasonic vibration within the inner portion of the mouthpiece. ## Claims ### Claim 1 An oral hygiene system, comprising: a mouthpiece having an outer portion and an inner portion configured to receive at least a portion of a user's dental and gum structures; a plurality of filaments disposed within the inner portion of the mouthpiece; a water pressure irrigator configured to be selectively coupled, in a first configuration, to the outer portion of the mouthpiece and to deliver fluid to the inner portion of the mouthpiece when in the first configuration, and to be selectively decoupled from the mouthpiece in a second configuration, in which a tip area of the water pressure irrigator is sized and shaped to deliver fluid to the user's dental and gum structures, independent of the mouthpiece; a handle rigidly connected to the water pressure irrigator; and a fluid reservoir in fluid communication with the water pressure irrigator and configured to deliver the fluid thereto, wherein the system is configured to generate ultrasound within the inner portion of the mouthpiece. ### Claim 2 (depends on 1) The oral hygiene system of claim 1, wherein: the tip area of the water pressure irrigator comprises a wedge-shaped tip having an elongated orifice, and the system is further configured to generate ultrasound at the tip of the water pressure irrigator. ### Claim 3 (depends on 1) The oral hygiene system of claim 1, wherein the mouthpiece further comprises a channel extending along the outer portion of the mouthpiece, such that fluid delivered from the water pressure irrigator travels along the channel and into the inner portion of the mouthpiece. ### Claim 4 (depends on 1) The oral hygiene system of claim 1, wherein each of the plurality of filaments is formed of silicone. ### Claim 5 (depends on 1) The oral hygiene system of claim 1, wherein the mouthpiece comprises a pair of opposed U-shaped walls and a transverse connecting wall, which together define the inner portion. ### Claim 6 (depends on 5) The oral hygiene system of claim 5, wherein the plurality of filaments project from each of the U-shaped walls and the connecting wall, at angles of from about 10 to about 90 degrees, relative to a surface of each wall. ### Claim 7 (depends on 5) The oral hygiene system of claim 5, wherein the plurality of filaments project perpendicularly from each of the U-shaped walls and the connecting wall. ### Claim 8 (depends on 1) The oral hygiene system of claim 1, wherein the system is further configured to generate an oscillating pulse within the inner portion of the mouthpiece. ### Claim 9 (depends on 8) The oral hygiene system of claim 8, wherein the oscillating pulse is a sonic vibration. ### Claim 10 An oral hygiene system, comprising: a mouthpiece having an outer portion and an inner portion configured to receive at least a portion of a user's dental and gum structures; a plurality of silicone filaments disposed within the inner portion of the mouthpiece; a water pressure irrigator configured to be selectively coupled to the outer portion of the mouthpiece and to deliver fluid to the inner portion of the mouthpiece, the water pressure irrigator comprising a wedge-shaped silicone tip having an elongated orifice; a handle rigidly connected to the water pressure irrigator; and a fluid reservoir in fluid communication with the water pressure irrigator and configured to deliver the fluid thereto, wherein the system is configured to generate ultrasound within the inner portion of the mouthpiece and at the tip of the water pressure irrigator. ### Claim 11 (depends on 10) The oral hygiene system of claim 10, wherein the mouthpiece further comprises a channel extending along the outer portion of the mouthpiece, such that fluid delivered from the water pressure irrigator travels along the channel and into the inner portion of the mouthpiece. ### Claim 12 (depends on 10) The oral hygiene system of claim 10, wherein the mouthpiece comprises a pair of opposed U-shaped walls and a transverse connecting wall, which together define the inner portion. ### Claim 13 (depends on 12) The oral hygiene system of claim 12, wherein the plurality of filaments project from each of the U-shaped walls and the connecting wall, at angles of from about 10 to about 90 degrees, relative to a surface of each wall. ### Claim 14 (depends on 12) The oral hygiene system of claim 12, wherein the plurality of filaments project perpendicularly from each of the U-shaped walls and the connecting wall. ### Claim 15 (depends on 10) The oral hygiene system of claim 10, wherein the system is further configured to generate an oscillating pulse within the inner portion of the mouthpiece. ### Claim 16 (depends on 15) The oral hygiene system of claim 15, wherein the oscillating pulse is a sonic vibration.
