Abstract
A system for oral irrigation comprises a fluid delivery tube () with a proximal end and a distal end. The proximal end is for receiving oral irrigation fluids. A nozzle () is placed at the distal end of the fluid delivery tube. The system further comprises an interdental sensor () for detecting whether the nozzle is in an interdental space, and a motion sensor () for measuring the displacement of the nozzle. A processor is configured to determine whether the nozzle () is moving along the occlusal surface of a tooth based on the displacement of the nozzle being larger than a critical distance, wherein the critical distance is indicative of the length of a tooth, and the interdental sensor () not detecting an interdental space during the displacement of the nozzle.
