A mouth douche including a water reservoir, a water pump and a nozzle insertable into the oral cavity is provided with a detachable power unit operable by a preferably rechargeable battery. The power unit advantageously is the body of an electric toothbrush insertable upside down, without its bristle-carrying head, into the base of the mouth douche for operative coupling of its shaft with the water pump. |
