  • Publication number: 20240081964
    Abstract: An electric toothbrush is disclosed, having a handle including a drive motor and a head portion removably coupled to the handle. The head portion includes a brush, an exit port fed by an internal irrigation lumen, and a drive shaft operatively connecting the drive motor to the brush. A disposable irrigant reservoir is removably coupled directly to the head portion. The irrigant reservoir is in fluid communication with the internal irrigation lumen of the head portion. The head portion is configured to be replaceable with respect to the handle, and the irrigant reservoir is configured to be replaceable independent of the head portion. In some examples, the irrigant reservoir is a disposable bulb (e.g., a capsule), and is positioned such that the user can hold the handle while also squeezing the reservoir with the same hand. In some examples, the toothbrush head includes a suction mechanism.

  • Publication number: 20230240822
    Abstract: A toothbrush system configured to be coupled to an external suction source. The toothbrush system includes a shaft with a main body with a first end and a second end, and a bristle array and a suction port arranged at the second end. The bristle array and the suction port both extend away from the shaft so that an opening of the suction port is proximal to a distal end of the bristle array. The shaft also includes a stem arranged at the first end. The stem includes a passageway that extends through the main body to provide a fluid connection to the suction port, and is configured to be coupled to the external suction source. Also, the handle is removably coupled to the shaft and includes a drive system operably coupled to the bristle array to actuate motion of the bristle array.

  • Publication number: 20220039928
    Abstract: A toothbrush for use by an operator and capable of being connected to a suction device and a syringe. The toothbrush includes a head, a handle, and a suction assembly. The head includes a plurality of bristles and an irrigation port configured to be in fluid communication with the syringe. The handle is coupled to the head and includes a user interface and a controller configured to actuate at least one of rotation, oscillation, and vibration of the plurality of bristles in response to feedback from the operator through the user interface. The suction assembly is coupled to one of the head and the handle and configured to be coupled to the suction device. The suction assembly includes a suction tip that is moveable relative to the head.
