Rotary electric toothbrush or sonic vibration toothbrush?

At that time, I bought an electric toothbrush for me, my mother and my father. My father is a thrifty person and it is the first time to use an electric toothbrush, so he chose the entry-level electric toothbrush with a relatively low price.The price is very good, it works very well, and while it's an entry-level model, it also uses proprietary stack hair transplant technology which gives the electric toothbrush  the benefit of a clean brush without cracking.The stack stack technique allows each bristle to rotate and vibrate individually, rather than the vibration of the toothbrush head to cause the bristles to vibrate. Therefore, when brushing, the electric toothbrush head does not knock, so my old father quickly adapted to it. It is really suitable for people who are just starting to use electric toothbrush.

My mother and I use an advanced electric toothbrush. Compared with my father's electric toothbrush, there are two more functional modes to use. There are five modes in total, including beginner (soft and easy to adapt, which my mother has always liked since the beginning of using electric toothbrush), clean, deep clean, sensitive and polished.Here, I must mention the sensitive mode of electric toothbrush. My gums are not in good condition. It was easy to bleed when I brushed my teeth before, but there was no bleeding after using this toothbrush.The timing function is also very useful, each part of the brush after enough time will remind you to change parts of the brush, to ensure that all areas of the mouth can be effectively cleaned.

Electric toothbrush is more and more popular, the functions and models of electric toothbrush are more and more complex, in the choice, there are often a lot of question marks, one of which is to choose the rotary electric toothbrush or acoustic vibration toothbrush is better, what is the difference between the two?Are electric toothbrushes more effective than manual toothbrushes?Are electric toothbrushes taxed on INTELLIGENCE?Are electric toothbrushes worth hundreds of yuan a scam?Another tax on our intelligence?Apparently not.A large body of scientific literature has proven that electric toothbrushes are indeed more effective than manual toothbrushes.

Dentists compared the effectiveness of electric and manual toothbrushes in removing plaque and improving the condition of gums. After four weeks of observation, electric toothbrushes were more effective than manual toothbrushes.The study was published in the American Journal of Dentistry.A large number of domestic studies have proved that electric toothbrushes are indeed effective.So we can rest assured that electric toothbrushes do work, not an IQ tax.What is the difference between rotary and sonic electric toothbrushes?Who is better?The working mode of these two toothbrushes is different, and we can clearly know the difference from the picture.The rotary electric toothbrush uses an electric motor to drive the bristles to rotate to remove dirt from the teeth.

The sonic vibration electric toothbrush uses a motor to drive the brush head to produce "high speed reciprocating vibration" at the frequency of sound waves to clean dirt from the tooth surface.The vibration frequency of electric toothbrush is usually 26,000 times/min, 31,000 times/min, 40,000 times/min, etc.
