A tongue cleaning device includes a tool head defining a trough that delivers the vacuum flow from an inlet to the inner surface disposed above a working edge for efficient removal of debris. The trough has a defined rear wall giving it a defined width. This allows the vacuum flow to be directed to where it is needed to remove debris. One configuration of the device has a head that defines a liquid distribution channel with an outlet disposed in front of the working edge with a supply of liquid being removably in fluid communication with the liquid distribution channel. The liquid supply being a bulk supply or a hand held bottle with a supply tube extending down the handle of the device. Another configuration of the device includes vacuum control openings controlled by the user's finger.
