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

My grandmother never brushed her teeth with an electric toothbrush in her life, and she can still open a bottle with her teeth -- an electric toothbrush would be even more of an intellectual tax for people who treat brushing their teeth as if it were just a nice thing to do. Others are stuck in the last century, when people were not well fed and warm enough to have a toothbrush, so they still think "keep your toothbrush clean" in the "I'll make sure I brush every day" mindset. Even if you get rid of the above two kinds of thinking, people will feel that the electric toothbrush is just an excuse for being lazy. A little diligence is enough. The electric toothbrush is just an accelerated version of manual brushing, which is so expensive that it is not cost-effective at all. First of all, most people have already realized the importance of brushing their teeth. If the people who don't brush their teeth should be taught the importance of brushing their teeth, then it is necessary to explain the advantages of electric toothbrushes to those who want to brush their teeth more cleanly. As mentioned above, electric toothbrushes not only brush faster, but are significantly more efficient and effective than manual toothbrushes. Not to mention pressure alarms, artificial intelligence and other features that can protect teeth by reducing wear and tear and help you develop healthier brushing habits. On the other hand, electric toothbrushes do cost more than regular toothbrushes. Is it worth the price? On the one hand, electric toothbrush is expensive because of its cost. Its structure is not only bristles and handle, but also vibration motor with adjustable frequency. On the other hand, electric toothbrush has many other functions: pressure alarm, artificial intelligence, timing function and so on, which are the multi-functional cost source of electric toothbrush; Finally, the electric toothbrush contains a variety of original instruments, as well as certain appearance level and waterproof performance requirements, industrial design and product process are far higher than ordinary toothbrushes, which also constitute another dimension of high cost of electric toothbrushes. All in all, electric toothbrushes have many advantages over ordinary toothbrushes except that they are more expensive. In this age of efficiency, electric toothbrush is definitely not an IQ tax, it will usher us into a new era of brushing teeth.

Electric toothbrush is not a labor-saving version of manual toothbrush. Many users have some misunderstandings about using electric toothbrush to brush their teeth, thinking that they can turn on the switch and put it in their mouth. In fact, if they cannot use electric toothbrush, the efficiency of brushing will be greatly reduced, and even improper use will increase tooth wear and gum damage.

Mom received the electric toothbrush, said that the appearance is not good, much better than her previous toothbrush. And she has a personal passion for design. It's a two-minute timer. My dad used to brush his teeth badly, so it might take less than a minute. Now with the timing feature, she can monitor my dad's complete brushing of electric toothbrush  of his teeth. Maybe anyone with a husband of the same style should use it too.
