An oscillating disk dental hygiene device of the present invention includes a quick coupling assembly having a first stage adapted to be coupled to a water source fixture and a second stage adapted to be quickly attachable and detachable from the first stage; a main housing defining a water chamber and having an inlet and an outlet, the inlet being coupled with the second stage of the quick coupling assembly; and a disk defining at least one opening therein and being disposed in the water chamber, the disk adapted to oscillate between a first substantially neutral position and a second position substantially obstructing the outlet when water entering the water chamber via the inlet has a pressure within a predetermined range, the oscillating disk creating a pulsating water stream exiting the water chamber via the outlet. A hand held nozzle is coupled to the outlet and is adapted to concentrate and direct the pulsating water stream into a pulsating water jet.
