A motor can be disposed within or coupled to the handle and configured to articulate the brush assembly within the mouthguard.

An electrical toothbrush system, device, method and kit are disclosed herein. In some embodiments, the system or device or kit include a suction lumen. In some embodiments, a display-control circuitry is provided, the circuitry configured to cause the display assembly to operate in the first or second display modes according to an elapsed-time-since-most-recent-operation, as measured by the timing circuitry.

An oral care system includes: an oral care device including a head having a reference face; and a plurality of sensors configured to generate sensor data, the sensor data including: motion data and orientation data corresponding, respectively, to motion measurements and orientation measurements of the reference face during a freeform oral care routine; and image data generated from external images of the oral cavity during the freeform oral care routine; and at least one programmable processor communicably coupled to the plurality of sensors, the at least one programmable processor configured to: generate transformed sensor data from the sensor data, the transformed sensor data comprising the orientation data transformed to be expressed in terms of an angular orientation system, the motion data, and enhanced image data, the enhanced image data representing each external image of the oral cavity combined with a representation of corresponding transformed orientation data.

A toothbrush comprising a drive mechanism and electronic circuitry configured to drive the drive mechanism to execute toothbrushing motions is disclosed. The electronic circuitry comprises a drive circuitry and a controller which is configured to form a drive signal to operate the drive circuitry to generate drive current. The drive signal comprises a plurality of signal packets, wherein a signal packet has a signal packet duration and comprises a train of switching signals. The switching signals are configured to repeatedly switch on and switch off drive current supply to the drive mechanism at a switching frequency f.sub.s. The signal packet duration is configured to define a rhythm of toothbrushing motions.

The present disclosure provides an electric toothbrush including a driving module, a connection shaft, a battery supporter, a support cover, a print circuit board and a switch. The driving module includes a driving element, a driving element supporter, a reset elastic element and a stress element. The connection shaft passes through the driving element supporter and the battery supporter. The driving element is used to drive the driving module to rotate from a starting position to a triggering position and make the reset elastic element generate elastic deformation. In the starting position, the driving element supporter is separated from the switch, and the switch is in an OFF state. In the triggering position, the driving element supporter contacts the switch and the switch is in an ON state, and the driving module rotates to the starting position with a reset force of the elastic deformation of the elastic element.
