Abstract: A free-standing oral hygiene device that is attachable to and detachable from a faucet member with one hand. An elongate flexible hose extends from the device to a hand-held wand which terminates in a nozzle that ejects a jet stream of water onto the teeth and gums of the user. When water pressure exceeds an adjustable preselected threshhold, a pressure relief valve opens so that the gums of the individual are not injured. A retaining clip member is depressed when the device is attached to the faucet, and released. When the retaining clip has been released, it holds the device to the faucet even when the water pressure from the faucet is very high. Removing the device is accomplished by depressing the retaining clip a second time and displacing the device downwardly. It can then be stored on a substantially level support surface as a free-standing unit.
