Is it necessary to buy an electric toothbrush?

In addition, some studies have shown that the risk of dental plaque and gingivitis is much lower after using an electric toothbrush.If we have an electric toothbrush and keep brushing for more than two minutes at a time, our teeth will be very white and healthy.

Then the biggest difference between electric toothbrush and ordinary toothbrush is that the electric toothbrush relies on motor to generate power, while the ordinary toothbrush relies on manual power, and the electric toothbrush needs to be charged before it can be used, while the ordinary toothbrush does not need to be charged.On the other hand, the electric toothbrush does not need to float back and forth by hand when it is in use, while the ordinary toothbrush needs to be brushed by hand. The vibration frequency of the electric toothbrush is relatively high, and the effect of removing dental plaque and tartar is better, while the ordinary toothbrush can only barely maintain the daily tooth cleaning.When using the electric toothbrush, we basically do not need to use their own force, so it is just the right force control.But the strength of the ordinary toothbrush is completely controlled by their own, I believe that we will usually have their own gum bleeding.

Electric toothbrush head structure has a great impact on the cleaning effect, fine and soft brush hair is easy to penetrate the gingival crevice and teeth, hard brush head is difficult to do, forced brushing seam will also damage the fragile gums, and even damage the enamel.

Electric toothbrushes on the market fall into two main genres.

Mechanical rotary electric toothbrush: using the rotation of the motor to drive the swing arm, simulated manual brushing, but faster and more violent (called a simple polishing machine!).The brush head and bristles rotate or reciprocate to achieve a clean effect by rubbing.

Sound wave vibration type electric toothbrush: rely on the high-speed movement of the motor to produce vibration, transfer to the bristles, produce a slight and fast movement, through the shock to achieve the effect of cleaning.

we need to pay attention to some of the parameters of the electric toothbrush when we buy the electric toothbrush, such as its battery life, cleaning strength and the use time of the bristles. These are more important and directly affect our subsequent use.1. Battery life Most of the electric toothbrushes on the market can last about 60~100 days, which depends on the frequency of each person using the electric toothbrush. For example, some people just brush their teeth morning and evening, and some people may alternately use the ordinary toothbrush and the electric toothbrush.2, cleaning force most of the automatic toothbrush timing in two minutes, because the more scientific brushing time is two minutes, it is best not to more than two minutes, but less than two minutes is not up to the cleaning effect.As for mechanical and acoustic electric toothbrush which good after all?Personally, I prefer a sonic electric toothbrush. Although the mechanical cleaning of tooth surfaces is very efficient, the sonic electric toothbrush can be easily cleaned to areas such as the gingival crevicular, and there is less physical wear on the teeth.
