The invention is directed to a device (1) for cleaning teeth and gums, which is provided with a liquid container (2) that is joined by way of a liquid supply conduit (7) to an inlet (8) of a pump (9) adapted to be driven by an electric motor (10). The pump, when activated, draws a liquid (3) from the liquid container (2) to the inlet (8). Still further, an air supply conduit (13) is provided which is connected to the liquid supply conduit (7) for the purpose of admixing air to the drawn liquid (3). According to the invention, at least a section (15) of the air supply conduit (13) is arranged at a level above a maximum possible level (14) of the liquid (3). This prevents the escape of liquid (3) from the device (1). |
