Before Buying Electric Toothbrush, First Understand Its Type
1. 2 rotary toothbrush
Rotary electric toothbrush work principle is to rely on the traditional axis of rotation around the brush head, resulting in friction to achieve the purpose of cleaning teeth, rotating electric toothbrush brush head will work around for pendulum movement.

2. Sonic toothbrush
Sonic toothbrushes do not use "sound waves" to brush their teeth. They are called sonic toothbrushes because the bristles / brush heads of such toothbrushes vibrate at or near the same frequency as the sound waves. Sonic toothbrush to achieve high-speed vibration generated by the motor-driven brush head to achieve the level of sound waves, sonic vibration Continuous and stable kinetic energy output inside the toothbrush to the top of the bristles, bristles vibration frequency up to 31000 times per minute, bristle top produce 4.5 m / s Of the extremely high speed to drive the flow of water and bubbles flow momentum, with super-clean than traditional manual toothbrush nearly 100 times. The experimental results show that the sonic toothbrush technology is higher than the rotary electric toothbrush, less likely to hurt the gums, and the cleaning ability is higher.
3 electric spray toothbrush
