Nowadays, people pay more and more attention to oral hygiene. In addition to cleaning their teeth regularly, they also pay attention to the selection of toothbrushes, from ordinary manual toothbrushes to current electric toothbrushes. Regarding electric toothbrushes, it is not worth starting, let Xiaobian tell you slowly.

　　Electric toothbrushes are mainly divided into two categories, which are distinguished according to their working principles. Different electric methods are different classifications. At present, electric toothbrushes are mainly divided into two categories: rotary electric toothbrushes and sonic electric toothbrushes.

　　The electric toothbrush brush head can be moved in three ways: one is a reciprocating linear motion of the brush head, the other is a rotary motion, and a complete set of electric toothbrushes with two types of brush heads. The bristles of the toothbrush head are made of soft plastic fibers, and the ends are processed into a spherical shape, which will not damage the teeth and gums, and will not affect the brushing effect.

　　Not only can each tooth be cleaned, but also it can massage the gums. The toothbrush handle has a strong and weak switching mode switch, and the speed of the toothbrush head can be selected according to individual needs.

　　Is an electric toothbrush good for rotation or sound?

　　The rotary type mainly achieves the cleaning effect by strengthening the massage force. It simulates manual tooth brushing, but it is faster than manual tooth brushing. The sonic type relies on the high-speed movement of the motor to drive the brush head to stabilize the high-speed vibration and generate a flowing cleaning force.

　　So, how good is an electric toothbrush?

　　Surveys show that electric toothbrushes are more scientific and effective than ordinary toothbrushes. It can remove dental plaque more thoroughly, reduce gingivitis and gum bleeding. It is also a daily necessities that are generally popular in many countries in Europe and America. This kind of healthy life is gradually spreading and spreading in China.

　　How often do electric toothbrush heads change

　　The replacement frequency of electric toothbrushes and ordinary toothbrushes is about 3 months!

　　1.The electric toothbrush can only replace the brush head.This is similar to the replacement of ordinary toothbrushes.It is about 3 months.If the bristles are better, it can be extended properly.It is generally replaced within half a year!

　　2, the life of electric toothbrushes is relatively long, different brands are different, basically using a 5 or 6 years is no problem, if it is well protected, it can take longer.

　　3.If it is a general brand electric toothbrush, some of the quality is just too good. Most of the life is like one or two years. Generally speaking, the life of electric toothbrushes is relatively long, mainly the brush head still takes about 3 months. One change!

　　Through the above analysis, I believe that everyone has a certain understanding of electric toothbrushes, and also has self-judgment in selecting toothbrushes.
