Abstract
A dental hygiene device has a brush assembly and a control unit. The brush assembly has a handle with suction and irrigation conduits passing therethrough. A brush head has two or more parallel rows of bristles. Suction and irrigation ports are positioned between the rows and coupled to the suction and irrigation conduits. Suction and irrigation tubes are coupled to the suction and irrigation conduits. The control unit has an irrigation outlet coupled to the irrigation tube and an irrigation pump, and a supply reservoir coupled to the irrigation pump. The supply reservoir contains a dental hygiene solution that is pumped from the supply reservoir through the irrigation outlet into the irrigation tube. The irrigation tube transmits the solution to the irrigation conduit and then to the irrigation port, where it is expelled. A suction inlet is coupled to the suction tube, and a suction pump is coupled to the suction inlet. A waste reservoir is coupled to the suction pump, which suctions the solution into the suction port to the suction tube, which transmits the solution to the suction inlet. The suction pump draws the solution from the suction inlet and expels the solution into the waste reservoir. The solution is an aqueous solution of sodium fluoride, from 0.5 to 1.0 milligrams per fluid ounce; and ascorbic acid from 350 to 425 times, bioflavinoids from 3 to 4.5 times, calcium ascorbate from 19 to 20 times, magnesium ascorbate from 9 to 10.5 times, and potassium ascorbate from 19 to 20 times the sodium fluoride concentration.
