Proposed is a mouthpiece-type electric toothbrush. The mouthpiece-type electric toothbrush includes a toothbrush body a first tooth insertion groove in which the upper teeth of a user are inserted and a second tooth insertion groove in which the lower teeth are inserted. The toothbrush body has a plurality of bristles having different lengths and formed in the first tooth insertion groove and the second tooth insertion groove in accordance with a tooth mold patterned after a row of teeth of the user.

In one embodiment, the invention may be a teeth cleaning device including: a first support structure comprising a first dentature channel configured to receive at least a first portion of a dentature of a user; a plurality of teeth cleaning pads located within the first dentature channel; a plurality of air bladders operably coupled to the teeth cleaning pads; an air-flow subsystem operably coupled to the air bladders; and a control unit operably coupled to the air-flow subsystem, the control unit configured to: (1) pressurize the air bladders with external air in a pressurization mode; and (2) transfer air between select ones of the air bladders in a cleaning mode.

A smart electric toothbrush showing the results of brushing by determining the brushing posture, which includes a brush handle and a brush head mounted on the brush handle, a motor in the brush head driving the brush head to work, and a controlling component electrically connected to the motor. A posture detection unit is located in the brush head electrically connected to the controlling component, and the posture detection unit includes a three-axis gyroscope and a three-axis accelerometer. Roll and pitch angles of the smart electric toothbrush are detected by the posture detection unit, and a brushing section is determined by the controlling component by detecting a posture of brushing after complementary filtering the roll angle and the pitch angle. By matching the determined position to the 16 sections, the user can be alarmed that which section is missing or over-brushing.

A method of charging a battery of a dental light irradiation device has the steps of powering the battery at a first charging current and measuring a first terminal voltage of the battery; powering the battery at a different second charging current and measuring a second terminal voltage of the battery; calculating a battery source voltage; and powering off the battery as soon as the battery source voltage reaches or exceeds the threshold voltage.
