Electric toothbrushes or and manual toothbrushes

Looking back on my transition from ordinary toothbrush to electric toothbrush, I did experience a lot of searching and learning at that time. This problem was even focused on learning before, which strengthened my determination to change from manual toothbrush to electric toothbrush.

In fact, the advantages and disadvantages of electric toothbrush compared with manual toothbrush, the masters in the front row have answered very complete, basically in the all-round comparison, electric toothbrush wins.

First of all, the brushing efficiency of electric toothbrush is far more than that of manual toothbrush. Our manual brushing is dozens of times per minute, while the frequency of electric toothbrush is as high as thousands of times per minute. As the frequency of brushing your teeth per unit of time increases, the cleaning ability naturally increases.

Second, the electric toothbrush is more friendly in terms of brushing. By vibrating or rotating at high frequencies, the electric toothbrush can better protect the gums and teeth, as opposed to the conventional toothbrush with the see-saw transverse brush.

And studies have shown that electric toothbrushes are better than manual ones at removing plaque. Volunteers were randomly divided into two groups for the detection of electric toothbrush and manual toothbrush. It was found that the efficiency of the electric toothbrush in plaque removal was significantly higher than that of the ordinary toothbrush.

If you don't want to force a defect, electricity, the purchase cost is high. But in addition to these two, both in terms of cleaning and oral protection, the electric toothbrush is better.

After these years of use, I know nothing about electric toothbrush from the very beginning. Until now, I can generally make toothbrush purchase more comfortable. So I would like to share some of my concerns about choosing an electric toothbrush.

Sound waves or rotation?

It is estimated that this is the first problem that all people face when they buy electric toothbrushes. Electric toothbrushes can be generally divided into two categories, that is, rotary electric (rotary) and acoustic electric.

Rotating electric means that the circular brush head is driven by the motor inside the toothbrush to rotate so as to realize brushing. The electric sonic toothbrush is easy to understand. It's similar to the round mop we use to mop the floor, but it's manually powered.

It also works in a way that is closer to our common toothbrush.

The sonic electric toothbrush may be called a sonic toothbrush, but it's not really a sonic toothbrush, it's a vibration. The brush head is driven by the machine to swing at high speed, and then the brush hair is driven to produce a small amplitude of high frequency vibration. Because the vibration frequency and sound frequency are close, so it is called sonic toothbrush.
