This invention creates a convenient low cost water pressure driven multi user oral cleansing device, the DentalJet with exchangeable color coded nozzle/handle which is easy to use, needs no electricity. The invention uses a faucet attachable rotating diverter, a flexible longer food grade PVC tube and interchangeable color coded jet nozzle/handle. The diverter also functions as a fine water volume/pressure control with a preset temperature and filter. Water pressure bulges up the flexible rubber tube clamped to the end of the adapter and to the PVC tubing. Inside the handle the water pressure created friction keeps the hose adapter in solid coupling while the pressure is on. The rubber tube oscillates, as pulsating water exist at the nozzle. When the water pressure is removed, color coded nozzle/handle is exchangeable.
