Are electric toothbrushes an IQ tax? How to buy an electric toothbrush?

1. It's not an IQ tax. Decades ago, electric toothbrushes were invented to solve the problem of people with hand defects who couldn't brush properly. Now, it is to solve the problem of lazy people not wanting to brush their teeth every day and brushing their teeth carelessly. You can't imagine how large this population is -- in 2019, the National Health Commission issued a "Healthy Oral Action" document, hoping that 45 percent of adults brush their teeth every day by 2025. It also reflects the gap in oral care education. Not so many people brush their teeth every day, the proportion of people who do not seriously brush their teeth will be as high as how many? Without an electric toothbrush, IT's hard for me to brush effectively myself. Effective here refers to the current mainstream recommended brushing method, which is also required in the oral examination of the future all doctors to jointly teach oral care method.

High frequency vibration of regular electric toothbrush can effectively protect oral diseases, but attention should be paid to the way of use to avoid soft tissue damage. Yes, compared with manual toothbrush, electric toothbrush still has disadvantages: 1. If the electric toothbrush has a low hair rounding rate, it will cause more serious damage to teeth in strong vibration mode. In other words, some patients reported that after using electric toothbrush, their teeth were actually "wedge-shaped defect", which could also be caused by the wrong choice of ordinary toothbrush. Electric toothbrush would accelerate. Electric toothbrushes are more expensive. Common toothbrush is the best brand, store goods to calculate 24 yuan, the common toothbrush of international brand is also mostly 10 yuan or so. However, electric toothbrush, such as some big brands electric toothbrush brush head often 60 yuan, most domestic brands about 30 yuan a; 3. Electric toothbrushes that do not charge in time will become ordinary manual toothbrushes. In particular, the battery life of the electric toothbrush will become shorter and shorter as the service life lengthens. It may become indispensable to the charger in one or two years, no matter you buy 22,000 or 200, do not hold too high expectations for you to use it for a long time. The battery will gradually deteriorate.

The more expensive the electric toothbrush, the better, especially in the fierce competition and the rise of domestic brands. From the price of electric toothbrush, the king of cost-effective brands, less than 200 yuan is enough to buy a good domestic electric toothbrush, imported electric toothbrush needs more than 300 yuan, the higher price is in the brand added value, marketing packaging cost, identity

and so on tax. High roundness rate of bristles and magnetic levitation motor are the entry threshold of a "good" electric toothbrush, and this most basic configuration can be achieved by domestic brands at 100 yuan.A good electric toothbrush can adjust the vibration frequency and pressure, and will sound if the pressure exceeds a certain value, which also protects teeth. So what we need to do is to adjust the frequency and vibration mode according to the instructions and stick the toothbrush on the tooth surface.
