4hw.com.cn: with the development of science and technology, a variety of new dental cleaning tools are competing. For example, the electric toothbrush, which is very popular in recent years, has become a new choice for modern people. So, what's good about the electric toothbrush? What's the difference with the toothbrush we usually use.
Advantages of electric toothbrush
1. Strong cleaning ability
Brushing can remove the plaque, followed by cleaning the dirt and stains. The cleaning ability of electric toothbrush is much higher than that of ordinary toothbrush, which can remove a certain proportion of plaque, effectively prevent gingivitis and periodontitis, so as to protect the health of oral gums.
2. Reduce tooth damage
Under the correct brushing method, the use of electric toothbrush can achieve a good cleaning effect, but few people can stick to the correct method of brushing, because this method of brushing is often time-consuming and laborious in actual operation, and the more commonly used saw or cross brushing method will damage the teeth and gums.
3. Easy to use
Another advantage you may often overlook is its convenience. Generally, people who use electric toothbrush are not used to it when they change back to ordinary toothbrush, because it is easy for people to have strong dependence.
Causes of gum injury of electric toothbrush
In fact, it is not the electric toothbrush that damages the gums, but the wrong way to brush teeth. Many people are afraid that their toothbrush is not clean, they will brush hard and "pull the saw" back and forth, but this may damage the gums and wear the teeth. Many studies have shown that electric toothbrush is better than manual toothbrush in reducing plaque and improving gingivitis.
Which kind of toothbrush is the cleanest
Electric rotary toothbrush & gt; sonic toothbrush & gt; ordinary toothbrush & gt; 5 battery vibration toothbrush
Generally speaking, the brush head of rotary toothbrush is relatively small. The brush head can cover the whole tooth directly, mainly to clean some dirt around the tooth by turning the brush hair after covering. The sonic type is a high-speed left and right swing through the brush, similar to the traditional manual brushing. Compared with the two, the power of the electric rotary toothbrush at the same price is greater than that of the sound wave, so the cleaning effect is better. But also because of the strength, the normal loss of enamel will be higher, and the rotary type is more noisy than the acoustic type. So why can't the vibration toothbrush with No. 5 battery work. Although its principle is similar to that of acoustic wave, its effective vibration frequency is even lower than that of manual brushing.
