Electric toothbrush is becoming more and more popular, and the functions and models of electric toothbrush are becoming more and more complex. When choosing electric toothbrush, there are often many question marks, one of which is whether it is better to choose rotary electric toothbrush or acoustic vibration toothbrush. What is the difference between the two?
What is the difference between rotary and acoustic electric toothbrushes? Who is better? These two toothbrushes work in different modes, and the picture shows the difference between them. The rotary electric toothbrush is driven by an electric motor to rotate the bristles, and through the rotation, the dirt on the teeth is removed.
The acoustic vibration type is to use the motor to drive the brush head to produce "high speed reciprocating vibration" to reach the frequency level of acoustic waves, and clean the dirt on the surface of the teeth through rapid vibration. Electric toothbrush vibration frequency is usually 26,000 times/min, 31,000 times/min, 40000 times/min, etc.
Rotating electric toothbrush and acoustic vibration electric toothbrush are the mainstream of electric toothbrush at present. Which is better or worse? Who is it? The medical community has also done a lot of clinical research on this issue. The study found that the rotary toothbrush cleaned teeth better than the sonic one. However, the rotary toothbrush did more damage to teeth than the sonic one, and people who were sensitive to the gums were not as friendly.
Is an electric toothbrush more effective than a manual toothbrush? Is the electric toothbrush an IQ tax? A few hundred yuan electric toothbrush is a scam? Is it our IQ tax again? Apparently not. A large body of scientific literature has proven that electric toothbrushes are indeed more effective than manual toothbrushes. Is a few hundred yuan electric toothbrush a scam? Is it our IQ tax again? Apparently not. A large body of scientific literature proves that electric toothbrushes are indeed more effective than manual toothbrushes.
Choose an electric toothbrush, there is also a focus that is often ignored by everyone, is to look at the work of the bristles. The tips of the bristles should be rounded so that they can be cleaned effectively and not hurt teeth.
Why use an electric toothbrush and what are the benefits? Many people around me have this attitude about electric toothbrushes. "As for being lazy like that?" "You don't like cleaning, a toothbrush can make you love brushing your teeth?" "It's all a scam," but the science is that brushing time is 2 minutes. This makes many people overestimate the amount of time they spend brushing their teeth. You may think you've been brushing for two minutes, but it might only take you 30 seconds. Even if you brush for a full two minutes, the manual brush is about 250 strokes per minute, and the electric toothbrush averages more than 30,000 strokes per minute. Using an electric toothbrush can improve brushing efficiency hundreds of times! Brushing a toothbrush is dental plaque, not just vegetable leaves, meat scraps, electric toothbrush vibration frequency can make the toothpaste and water mixture in the mouth to create a large number of tiny bubbles, bubbles burst when the pressure can be deep into the teeth to clean dirt. Literature has shown that compared with ordinary toothbrushes, electric toothbrushes can remove 12%~20% of dental plaque and reduce bleeding and inflammation of gums by 34%~50%.
