The present invention relates to an electric toothbrush that includes a head part and a handle part having a shape connectable to the head part and supplying a driving voltage to the head part according to a user's control. The head part may include a toothbrush head formed with a plurality of bristle holes where toothbrush bristles are disposed and a first through hole and a second through hole spaced apart from each other, a head body extending from the toothbrush head and having an inner passage connected to the first through hole and the second through hole, a head cover which closes the inner passage of the head body, and a first electrode rod and a second electrode rod inserted through the inner passage of the head body, whose one ends being positioned in the first through hole and the second through hole, respectively, and the other ends being exposed to the outside through the head cover, respectively.

The purpose of this invention is to improve the health of users while effectively utilizing data obtained from information about tooth brushing. One embodiment of the present invention is a server connected via a network to a user terminal communicating with an instrument equipped with a sensor that detects predetermined measurement information on tooth brushing, and to an evaluator terminal that inputs predetermined evaluations, which receives measurement information on tooth brushing detected by the sensor, receives the measurement information on tooth brushing, receives the receiving habit information of a user who performs tooth brushing, and transmits the evaluation information based on the measurement information and the habit information to the user terminal.

A teeth cleaning apparatus includes a mouthpiece, a transducer, a cleaning liquid supply unit and a power control unit. The mouthpiece includes a containment wall, a hollow ingress tube connector and a vibrator holder. The vibrator holder has a vibrator holder hole and a vibrator holder body, and the transducer has a stationary part and a vibrator part, wherein an end of the stationary part of the transducer is kept in the vibrator holder, and a vibrator part of the transducer is disposed near the containment wall. The cleaning liquid supply unit includes a cleaning liquid container, at least one connecting tube, and a cleaning liquid delivery unit that delivers a cleaning liquid from the cleaning liquid container through the hole of the hollow ingress tube connector of the mouthpiece piece. The power control unit is used for supplying electricity to operate the transducer to generate cavitation bubbles at a vibration frequency to dean teeth.

An oral care device comprises a head portion and a handle portion. The head portion comprises at least one supporting arm and a base. The supporting arm extends from the base. A sensor is exposed from the supporting arm. The handle portion is configured to move relative to the head portion. The handle portion comprises a processor, wherein the processor is configured to receive signals from the sensor and analyze the signals received from the sensor.

A method and apparatus permitting arbitrary, relative motions of a distal end of a toothbrush or flosser with respect to a handle with real-time selectable motions. The toothbrush has a handle and a post, with a mechanism mechanically coupling the handle to the post permitting relative translational movement of the post with respect to the handle.

The present invention relates to an electric or motorized toothbrush. The toothbrush contains a brush head having bristles that rotate in either a clockwise or counterclockwise direction in a non-oscillating manner. An elongated handle contains a motor, rechargeable batteries and a rotatable shaft to rotate the bristles in a desired direction. The bristles are rotated using manual control buttons disposed on the handle. Typically, a clockwise rotation is performed for cleaning top teeth and a counterclockwise rotation is performed for cleaning bottom teeth. The toothbrush enables users to change the brush direction for top and bottom teeth without having to switch hands.

The present invention relates to a comprehensive oral care system. The oral care system provides users with an improved dental cleaning system to ensure people can practice optimal oral care routines. The system has an extendable mouthpiece for receiving the teeth and the tongue of a user. The mouthpiece has a plurality of brushes, and more specifically, three brushes for each tooth for brushing. The mouthpiece also releases water, dental rinse agents, and mouthwash for providing complete oral care. The system has a touch panel that can be used for configuration of parameters like speed and pressure of brushes, amount of water, dental rinse agents and mouthwash and other solutions for meeting requirements of individual users. The system uses a digitized dental mold for configuration and generation of the mouthpiece to create a replica of the jaw of users.

The mouth piece toothbrush is a medical device. The mouth piece toothbrush is adapted for use with a patient. The mouth piece toothbrush is a mouthpiece. The mouth piece toothbrush is adapted for use in cleaning the dentition of the patient. The mouth piece toothbrush comprises a dental tray, a plurality of cleaning structures, and a control circuit. The dental tray houses the plurality of cleaning structures and the control circuit. The plurality of cleaning structures clean the dentition of the patient. Each of the plurality of cleaning structures is an electrically powered device. The control circuit controls the operation of the plurality of cleaning structures. The dental tray simultaneously receives the mandibular dental arch and the maxillary dental arch for cleaning.

A brush head of a toothbrush includes a plurality of bristles for cleaning teeth and a sensor unit for monitoring the health status of a user regarding development of paradontitis, cavities, periodontitis, and/or for health monitoring. The sensor unit is exchangeably arranged on or in the brush head.

A brush includes a head with bristles, an actuator that expands and contracts in accordance with an electric signal, a connection member that transmits vibration of the actuator to the head, and a body including a housing that houses the actuator. The direction of reciprocal vibration of the head is at a predetermined angle relative to the direction of extension of the housing.
