How to choose an electric toothbrush

How to choose an electric toothbrush? Choose an acoustic or non-acoustic toothbrush? Non-acoustic electric toothbrush is cleaned by rubbing the brush head with teeth, but the frequency of swinging the electric bristles is higher, and the cleaning effect is better than manual. The cleaning principle relies on high speed friction to clean dirt and dental plaque. The acoustic electric toothbrush uses an ultrasonic transducer hidden in the brush head to cause the brush head to produce high frequency vibration, which can loosen or even shake off the dental plaque, tartar and undetectable early dental calculus on the tooth surface.

In this regard, I choose the sonic type electric toothbrush. Here's why: The acoustic version is safer for the teeth. On average, rotary electric toothbrushes cause four to five times more tooth wear than sonic toothbrushes. The rotation rate is very fast, which is more abrasion to the teeth. Sonic toothbrushes are gentler and less noisy. When rotary toothbrush is used, the vibration is larger, and it is easier to make the gums bleed, and the noise generated by rotary toothbrush is larger. (PS: No matter what kind of electric toothbrush will be noisy, the first time to use may be a little bit uncomfortable oh)

Toothbrush this thing, every use can not do without water, so I think waterproof ability is a very important reference aspect. After all, if the brush head can be changed to last something, if it is not waterproof, it will not be long before you have to buy it again. That would be very uncomfortable!

For electric toothbrush, I think it is ok to charge a power tube for about 20 days a month. If the battery life is too short, it will be inconvenient to use and even add some troubles to life. Of course, longer battery life would be even better!

Although the electric toothbrush only needs to press a button, but I still feel that if there are different gears, timing and transposing functions, it will be easier to use and more convenient. As for appearance level problem, the person is meeting to pursue beautiful thing, even if be toothbrush, appearance level went up also can add a lot of points!

Electric toothbrush is a popular electronic consumer product in recent years. Its advantages are convenient to use and higher cleaning efficiency than ordinary toothbrush. It is an ideal oral cleaning necessity at present. But there are so many brands on the market, types and main functions are different, many people choose electric toothbrushes only look at the cleaning force, which is very blind, to know that the overall dental quality of Chinese people is not high, there are many problems such as tooth decay, choose too strong electric toothbrushes will lead to tooth wear, gingival atrophy bleeding, teeth crack and other problems!

Electric toothbrush from dozens to thousands of prices have, there is a saying that you get what you pay for, the price of the interval is divided so large is also for a reason, less than 100 electric toothbrush do not buy, the quality experience is really a long story, pit money is second, if hurt the oral gum is too irritating. Compared with the rotary type, it is recommended to choose the sonic electric toothbrush first. The technology is mature and is the technology chosen by the vast majority of manufacturers at present. The frequency is generally 30,000-40000 times/min, which is very appropriate. High-quality toothbrushes generally use DuPont bristles, and through high grinding round treatment. The following figure is a schematic diagram of the grinding rate. Many sharp burrs can be seen by the naked eye of the unpolished bristles, which are easy to scratch the gums!
