Why do many people say that using an electric toothbrush is an IQ tax

The so-called experience assessment is nothing more than putting the toothbrush in the water and taking a small video of the water shaking. Most of the answers I don't look at are too watery. I don't think I have enough voice if I don't experience a toothbrush by myself (I really brush my teeth with this toothbrush in the morning and evening) for more than 3 months. I've been using electric toothbrush for 5 years myself, but not as many as those who review electric toothbrushes have toothbrushes in their hands, just to share their experience.

Can't believe 2021 is the year electric toothbrush still haven't removed the stigma of the IQ tax... The last time I answered this kind of question was euphemistic, which was to ask "why dentists do not agree to use electric toothbrush". Then I did a small survey in my circle of friends among oral doctors. In order to save time, each type of electric toothbrush here only brushes about 50 years, which is indeed excellent in cleaning teeth. However, it works by physical friction and rotation, so stains still remain on the surface of teeth during brushing. The high frequency vibration of the horizontal electric toothbrush can easily peel the tooth stains off the tooth surface, and at the same time, it can also reduce the damage of tooth enamel. The cleaning power is also visible to the naked eye, and the cleaning effect of not only the tooth surface, but also the periodontal space is very ideal. Based on the 2 minutes of our normal electric toothbrush, this horizontal electric toothbrush can clean the entire tooth mold completely, but it takes 3 to 4 minutes to clean the entire tooth mold. Back to say the pair, part of an electric toothbrush cleaning effect is better than ordinary toothbrush, even this I very agree with you, a price a points goods we all understand this truth, electric toothbrush ok or not largely depends on the motor, watching video, electric tooth brush on the tooth surface didn't swing, a see be dozens of pieces of a pair of eccentric wheel motors, The price of the mainstream magnetic levitation motor on the market is only more than 200, and the cleaning ability is not worse than the rotary effect. And a good electric toothbrush of choose and buy besides clean effect this one element, still follow brush bristle, vibration frequency, endurance ability, noise to hook up directly.

When it comes to electric toothbrush, you can try the big brands. The big brands have strong cleaning power and good product quality, which have won many praises. The only disadvantage is a little more expensive than domestic brands! But the cleanliness and the experience are great, and it's actually worth it. But the cleanliness and the experience are great, and it's actually worth it. First of all, briefly introduce the characteristics of electric toothbrush: the higher the price of electric toothbrush, the better the appearance and feel, and the more functions. Except for a few low-priced models, the vibration frequency is 31000 times/min, and the power is very stable. The endurance is between 14 and 20 days. The price of brush head is about 50 yuan, dupont imported soft hair, can go deep into the narrow gap to remove plaque. In addition, the electric toothbrush models with similar prices have similar other configurations, except some accessories or appearance differences, so it is not necessary to understand each model.
