Claim:
1. A dental hygiene system that discharges a liquid containing particles dispersed from a solid dental cleansing compound for impinging the particles against the teeth of a user, the system comprising: a dispersing device comprising a housing, the housing comprising an inlet for connection to a source of liquid, a discharge for discharge of the liquid from the housing, and a fluid line extending through the housing fluidly connecting the inlet and the discharge to flow a liquid stream through the housing from the inlet to the discharge, the fluid line defining a downstream direction from the inlet to the discharge and an opposite upstream direction, a portion of the fluid line defining a dispersing chamber having an interior volume to receive the solid dental cleansing compound in the dispersing chamber, the dispersing chamber having a downstream side, a first body in the dispersing chamber disposed on the downstream side of the dispersing chamber, the first body having a plurality of openings that allow particles of a predetermined maximum size to pass through the first body, and a holder in the fluid line that obstructs upstream movement of the solid dental cleansing compound in the dispersing chamber; the dispersing chamber is configured to receive the solid dental cleansing compound and to provide clearance between the dispersing chamber and the solid dental cleansing compound when the solid dental cleansing compound is centered in the liquid stream to enable liquid flowing through the dispersing chamber to wet all sides of the solid dental cleansing compound; the holder comprises at least one member, the at least one member being at least semi-elastic and generating a force to locate the solid dental cleansing compound in the dispersing chamber, the force being applied to the solid dental cleansing compound and pressing the solid dental cleansing compound against the first body when the solid dental cleansing compound is in the dispersing chamber; and the holder permits displacement of the solid dental cleansing compound with respect to the holder when the solid dental cleansing compound is in the dispersing chamber to permit movement of the solid dental cleansing compound in the liquid stream caused by liquid flowing past the solid dental cleansing compound.
