Electric toothbrush refers to the toothbrush driven by electricity, which is mainly divided into mechanical rotation type and acoustic vibration mode. Their main difference is their different principles. The mechanical rotary electric toothbrush drives the brush handle to rotate at high speed through the motor in the machine body to achieve the effect of cleaning teeth, and the revolutions per minute are between several thousand and 30 thousand 1 thousand; Acoustic vibration electric toothbrush, referred to as acoustic toothbrush for short, drives the brush head to vibrate at low frequency and high amplitude through the motor in the machine body to realize the function of cleaning teeth, and the vibration times per minute range from several thousand to 40 thousand; On the whole, the cleaning effect of mechanical rotation is slightly better than that of acoustic vibration, but the enamel wear is 2-3 times that of acoustic vibration. On the whole, users are advised to buy sonic toothbrushes!
