What should I pay attention to when buying an electric toothbrush?

As a researcher, I did some research on this new species before I bought it and compared it to a regular manual toothbrush. First of all, there is no denying that electric toothbrushes have been proved to have better cleaning ability in many papers and practical cases. It's certainly not an IQ tax in terms of the practicality of cleanliness, but some of the claims made me question it. For example, the electric toothbrush can remove stubborn tooth stones, such as the motor vibration speed increased by several hundred times/second price also rose by several hundred, more and more fight the visible "number", vibration speed and endurance have been inside the roll, but the electric toothbrush as a toothbrush, the really important brush bristles are little attention and research and development.

The official motor shock speed does not mean that the cleaning effect is good. The motor of electric toothbrush has the same shock speed per minute. Whether you are a few hundred yuan or a thousand yuan electric toothbrush, the general motor shock speed is about 10,000-40,000 times. To take a simple example, the speed limit is not more than 200km/h, then 500km/h is not practical, but more important is how to enjoy the quiet driving environment while driving safely at high speed. The bristles, as the core component of the electric toothbrush, are actually like the safety system of a car. With the right vibration frequency, comfortable bristles, and plenty of features, and at the right price, electric toothbrushes are a good product, not a tax. Because of my own good experience, my small family has all used electric toothbrush, also began to arrange this "small appliances" to improve the quality of life for the large family. For those of you who follow me regularly, I'm a big fan of buying things for my parents, from vitamins to fish oil, from the scale to the TV. However, my parents' generation of middle-aged and old people are very economical, an electric toothbrush can be used to fly out in all directions are not willing to change. Maybe you have the same mom or dad and the same "badly used" electric toothbrush at home. In fact, many middle-aged and elderly people have caused irreparable damage because of money saving or the wrong concept of cleanliness. For example, my mother's teeth are so sensitive that she needs painkillers for a few days every year. My father's teeth didn't hurt, but years of smoking and drinking made them look terrible. At my urging, they finally replaced the flying electric toothbrush with cheaper ones issued by hotels.

In order to let my parents experience electric toothbrush, I set foot on a long way to find an electric toothbrush with strong cleaning power but not damaging the gum enamel and sensitive teeth. At the same time, its price is not too high. After my parents learned to shop online, I guess they could not be cheated by deliberately saying the low price. After comparing the official data of various manufacturers and the real experience feedback of netizens, I took advantage of the promotion to buy an electric toothbrush for my mother to try first, and after passing my mother's approval, I will buy it for my father.
