A method and apparatus for oral hygiene, in particular having an oral hygiene device similar to a WATER PIK® brand device which has a pump with an inlet port and an outlet nozzle. A reservoir is placed in a sink above a drain and below a faucet and water from the faucet is adjusted for temperature and flows into the reservoir and over and into the drain of the sink. A conduit is provided between the inlet of the pump and the outlet of the reservoir so that, in use, a person can first adjust the temperature of the water in the reservoir and then turn on the pump and use the oral hygiene device as with any other oral hygiene apparatus while either allowing the water to continue to flow from the faucet at the desired temperature; or, if desired, to stop the flow and put medication into the container before use so that the water and medication solution is used rather than just water.
