Electric toothbrush is a product of scientific and technological progress. Relying on motor vibration, it can achieve a cleaning efficiency that cannot be achieved by human hands. Using sonic toothbrush correctly is also safer than manual brushing. When steam trains were invented instead of livestock, allowing us to get to our destinations more efficiently, the development of transportation allowed us to reach boundaries far beyond our feet. In fact, the toothbrush is also in continuous development, continuous iteration update. And the human "brushing history" is also the same, from the earliest hand to clean teeth, to the use of animal hair when the brush, and then to the industrial civilization of nylon wire when the brush, and then to the industrial production of nylon wire more and more fine, can be made into any hardness and surface grinding round, these have prepared for the appearance of electric toothbrush. Then, electric toothbrush appeared, it relies on the vibration of the motor to complete the human hand speed can not achieve the cleaning efficiency, toothbrush entered a new era.

Many electric toothbrushes on the market use adjectives such as "sound wave" and "ultrasonic wave" to make people think that they rely on the power of sound wave or ultrasonic wave to clean teeth. In fact, they do not use sound wave to brush teeth, but the bristles similar to the vibration frequency of sound wave to clean teeth. So how much is the vibration frequency of the general acoustic electric toothbrush? Electric toothbrushes on the market vibrate between 20,000 and 40,000 times per minute. Most electric toothbrushes focus on 30,000 to 35,000 times per minute. While most of us brush our teeth with our hands at 3-6 times a second, that's 180-360 times a minute, which means that electric toothbrushes vibrate 100 to 200 times faster than human hands.

The cleaning efficiency of manual brushing is closely related to the way and time of brushing, while horizontal brushing is inefficient and easy to damage teeth. The Pap brushing method is efficient, but it is also difficult to brush and not easy to master. The vibration frequency of sonic toothbrush is much higher than manual brush speed, so it is far more efficient than manual toothbrush in cleaning. The high-frequency vibrations of an electric toothbrush can help quickly clean the plaque on your teeth, simply by holding it in the right place.

There are two categories of electric toothbrushes, one is the round head brush head, mainly rotating and swinging clean; The other type is the common bristle shape, which is mainly reciprocating vibration to clean. Round head brush head can take care of the teeth of a variety of convex and concave structure, the movement direction of the brush along the tangent of the round head swing and rotation, brush bristles can be deep into a variety of teeth and grooves, has a strong mechanical cleaning effect and cleaning effect. However, the brush head with the shape of ordinary rectangular bristles has reciprocating motion. If it is inserted horizontally into the gingival crevise, it can quickly clean the gingival crevise by imitating The Pasteur brushing method. Meanwhile, the reciprocating motion can also drive the water to vibrate and enter the middle of the tooth gap, which has a certain cleaning effect on the adjacent surface of the teeth.
