Oscillating disk dental hygiene device

A method of generating pulsating water jet to clean teeth and massage gums, and comprising:

• coupling an inlet of a pulsating water wave generator of an oscillating disk dental hygiene device onto a water source;
• providing water at a predetermined water pressure entering the inlet and reaching a water chamber of the pulsating water wave generator, and permitting the water to flow through at least one opening defined in a free-floating disk positioned in the water chamber, the disk having an inlet side and an outlet side;
• increasing the water pressure at the inlet side of the disk due to the inlet being greater than at least one opening of the disk, the water pressure being built up at the inlet side of the disk rapidly, outlet side water being discharged and not able to build much pressure, the pressure unbalance between the inlet and outlet side pushing the disk against a biasing spring and toward the outlet opening protruding into the water chamber leading out to the outlet;
• continuing to permit the water to flow through the at least one opening in the disk so that when the outlet side water pressure equalizes or nearly equalizes with the inlet pressure combined with the defection rate of the compressed disk and the biasing spring, causing greater pressure at the outlet side of the disk than the inlet side, the disk instantaneously returns toward to its neutral position spaced from the discharge opening;
• again permitting the disk to be pushed against the biasing spring toward the discharge opening by the intake water pressure, causing a continuous oscillating motion in the disk thereby creating pulsating water waves;
• and
• ejecting and directing the pulsating water waves in the form of a pulsating water jet.
