1. Electric toothbrush is convenient and quick, but ordinary toothbrush is inconvenient.

In the case of traditional manual soft-bristle toothbrush, we need to push the soft-bristle toothbrush to brush teeth back and forth in the mouth and repeat the movement of this mechanical device. In addition, you need to master the scope, time and direction of brushing your teeth. Some people feel too tired after brushing for a while, and then they don't brush seriously. At this point, the sonic electric toothbrush will be more convenient and faster.

2. Electric toothbrushes are expensive, while ordinary toothbrushes are cheap.

On the price level of both, the price of acoustic electric toothbrush is obviously more expensive than that of ordinary manual soft-bristle toothbrush. Some sonic electric toothbrushes need to be replaced, and charging is more expensive.

3. Electric toothbrush is not suitable for anyone, but ordinary toothbrush.

Although the sonic electric toothbrush is good, some people are not used to it. Because of its high vibration frequency and noise, some people report that the use of sonic electric toothbrush will cause dizziness, so it is not recommended to use sonic electric toothbrush at this time. It is aimed at children. In fact, there is no need to use sonic electric toothbrush, but attention should be paid to choosing low-frequency sonic electric toothbrush for cleaning.
