Why are electric toothbrushes better than regular toothbrushes?

Although the use of electric toothbrush has become more and more common, but the mainstream oral cleaning tool is still ordinary toothbrush, electric toothbrush is still exclusive to young people is not the mainstream "mass product". In the dental clinic we were in, for example, many of the young doctors close to my age had switched to electric toothbrushes, while the old director had never used them and was unwilling to try...... 1, vibration frequency back to the point, no matter what tool you choose to brush your teeth, the ultimate goal is to remove plaque and fresh breath. The frequency of manual brushing of normal people is 220 times/minute, while the vibration frequency of mainstream electric toothbrush is 20,000-40000 times/minute, which means that the cleaning efficiency of electric toothbrush is much higher than that of manual brushing in the same time. 2. Brushing method on the other hand is the correct way to brush teeth. The internationally recognized method of brushing teeth is the Pap brushing method. If you follow the Pap method strictly, very few people can consistently use it correctly. The electric toothbrush has its own time reminder, cleaning mode selection, pressure reminder and other functions, which can help us better master the correct way of Brushing. The third point is that more cleaning modes are suitable for more people. Different people have different degree of tooth sensitivity, and they have different requirements for the strength of electric toothbrush. Due to the simple design of ordinary toothbrush, the strength of use can only be adjusted by hand, which is not only very tired but also may aggravate their periodontitis, tooth sensitivity and other problems. Electric toothbrushes come with different cleaning modes. Low-end toothbrushes have at least 2-3 cleaning modes, and high-end toothbrushes even have 4-6 cleaning modes. More lost is not always better, but it can meet the actual needs of our teeth in a way that ordinary toothbrushes can't. 4, the cost of using the cost of the early investment in electric toothbrush is very large, spend two or three hundred can buy a better domestic brand, more than three hundred is the position of imported brands. I to electric toothbrush brand attention is not high, in my more or less used more than a dozen electric toothbrush, the actual feeling is domestic electric toothbrush slings at the same price imported toothbrush, and is killed that..... Another cost is the cost of replacing the brush head. Most of the domestic brushes cost more than 20 pieces, which is not too excessive compared to the price of ordinary toothbrushes of about 10 yuan. As long as the quality of brush head is good enough and the circular grinding rate reaches the national standard, we can choose the price from low to high.

After I go to work to now a few years of time, more or less used more than a dozen electric toothbrush....... Even smelly shameless used some brands of children's electric toothbrush, but also very good.
