The present invention describes a method for a U-shaped teeth brush device having a conformable shape adjusting U-shaped teethbrush module and one or more individual tooth brushes coupled to the power drive mechanism, each brush having a sensor, piezoelectric crystal and transducer and each tooth brush having a block anchor coupled to the power drive, under smart controls, an electronic control system for sensing individual tooth pressure and controlling motor transmission of vibration to prior positioned brushes, whereby a users unique mouth features can be accounted for by adjusting U-shape distal ends to fit through the users mouth and align with users teeth arch for programmatically brushing more than one tooth simultaneously.

Various embodiments for cleaning carious regions of a tooth are disclosed herein. For example, a dental apparatus can include a fluid platform having a chamber sized and shaped to retain fluid. The chamber can be configured to be coupled to the tooth over the carious region. A pressure wave generator having a distal end may be configured to be positioned in the chamber. The pressure wave generator may be configured to generate pressure waves in the retained fluid sufficient to clean the carious region.

A system for oral irrigation comprises a fluid delivery tube (102) with a proximal end and a distal end. The proximal end is for receiving oral irrigation fluids. A nozzle (104) is placed at the distal end of the fluid delivery tube. The system further comprises an interdental sensor (2002) for detecting whether the nozzle is in an interdental space, and a motion sensor (2004) for measuring the displacement of the nozzle. A processor is configured to determine whether the nozzle (104) 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 (2002) not detecting an interdental space during the displacement of the nozzle.

Systems and methods for using a liquid jet apparatus for dental treatments are disclosed. In one implementation, the liquid jet apparatus may include a handpiece configured to deliver a high velocity liquid jet to a desired location in the mouth of a patient. The handpiece may include a positioning member having a channel through or along which the jet can propagate. The positioning member may have a distal end portion configured to be at least partially disposed in a pulp cavity, canal space, or opening in the tooth under treatment. During operation, the jet may impact an impingement surface of the distal end portion of the positioning member and be deflected as a spray through one or more openings in the distal end portion. The liquid jet apparatus may be used for root canal treatments.

An electric toothbrush includes a handle provided with a liquid feeding port, a toothbrush head connected to the handle and provided with a liquid discharging port communicated to the liquid feeding port through a liquid transfer passageway, a pumping mechanism disposed at the liquid transfer passageway and used for providing a pumping force for the liquid transfer passageway so as to transfer liquid from the liquid feeding port to the liquid discharging port and spray the liquid, and a transmission mechanism disposed on the handle and connected to the toothbrush head to drive the toothbrush head have a reciprocating motion relative to the handle.
