1. A dental cleaning device for simultaneously brushing at a plurality of dental positions, the dental cleaning device comprising:
a mouthpiece having a pressure chamber and a recess which is U-shaped in cross section and delimited by a flexible or deformable recess wall, the pressure chamber being configured for containing a fluid under pressure,
a pump unit arranged in fluid communication with said pressure chamber, the pump unit being configured to reciprocatingly increase and decrease a pressure in the pressure chamber between an increased pressure condition and a decreased pressure condition by pumping a volume of fluid into and out of the pressure chamber, thereby deforming the recess wall and moving the recess wall back and forth;
a pressure sensor configured to measure a pressure representative of the pressure in the pressure chamber and to produce a pressure signal representative of said pressure;
a controller integrated with a printed circuit board configured to generate a control signal;
wherein the pressure sensor and the controller are connected such that the controller, in use, receives the pressure signal from the pressure sensor;
wherein the controller and the pump unit are connected such that the pump unit, in use, receives the control signal from the controller;
wherein the controller is configured to generate the control signal in dependence on the pressure signal and the pump unit is configured to provide a delivery into and/or out of the pressure chamber in response to the control signal; and
wherein the controller is configured to reduce the delivery of the pump unit when the pressure in the pressure chamber exceeds a predetermined upper threshold.
