These years, your brushing method may be wrong.

Brush your teeth in the morning and go out and brush your teeth at night to stimulate your libido.

Brushing teeth has become a part of modern civilized life and is no longer a patent of the royal family.

"Tooth brush twice a day" is a slogan that is so popular that some dental manuals no longer advise dentists to ask patients whether to "brush their teeth" or "brush a few times a day." Because even if he/she doesn't do that, he/she knows what to say.

But do you really know how to brush your teeth and brush your teeth? I don't think so.

The first is the number of brushing. Do you really accept that you should brush your teeth twice a day? In addition to decent and libido, are there other reasons to support brushing?

Of course! This begins with the purpose of brushing your teeth.

What should I brush off from my teeth?

Leftovers? Pork? Chives leaves? To brush, it is actually bacteria, more precisely, plaque.

Plaque is the form of bacteria on the teeth. Like a film, it sticks to the teeth and is the precursor of the calculus.

Note that plaque is stuck to the teeth, unlike the dust on the tabletop, like the oil on the exhaust hood. The light mouth opens the mouth and lets the wind blow like a mouthful of water. It can't be removed; it must be wiped with force.

The bacteria in the mouth are endless, the wildfires are not burning, and the spring breeze blows again. If left unchecked, the bacterial family would be four generations after a few hours; in a dozen or so hours, they began to damage the teeth and gums, causing tooth decay, gingivitis, bad breath and so on.

In this case, we can't take the old road of "polluting and then re-treating", so we have to brush our teeth twice a day. It's like urban management patrols, although it is impossible to eliminate all hawkers, but at least it can make the road clean and orderly.

Then let's get to the point: how to brush your teeth.

How to brush your teeth?

Direction of the bristles

The most important thing to brush your teeth is the direction of the bristles. The bristles are placed at an angle of 45 degrees between the teeth and the gums. This is the core technology of contemporary scientific brushing, no matter what toothbrush you use.

The friend who asked the bottom of the question should ask again, why?

The purpose of our brushing is to brush the plaque, and it is easy to grow in the middle third of the tooth close to the gum, even in the gap between the tooth and the gum.

Therefore, only when the brush is inclined at 45 degrees, the plaque can be effectively removed.

2. What should I do with bleeding gums?

Some people will worry, then will this brush the gums? Will it brush bleeding?

Why is the gums bleeding? It is white because the gums are dirty. If it is dirty, it will cause inflammation of the gums, and the inflamed gums will easily bleed. The gums that are prone to bleeding will make you afraid to brush your gums, so that the gums become more and more dirty, and the more dirty the gums become more inflammatory... just enter a vicious circle.

Therefore, the bleeding of the gums is not terrible, the bleeding should be brushed, and the more bleeding, the better the brush.

After the brush is cleaned, the gums are anti-inflammatory, and naturally there is no bleeding. The healthy gums are not afraid of brushing. Of course, if you brush it for a week, it still bleeds a lot, which means that some dirty things that can't be removed by brushing your teeth stick to your teeth, and you need to wash your teeth.

3. The extent of brushing

The toothbrush position is right, how to brush it?

The correct way is tremor, a small horizontal movement that does not exceed the width of one or two teeth. One tooth, one tooth, from front to back, from back to front, all the way.

Don't open your mouth, because "one inch long and one inch strong", the magnitude is large, and the power is not well controlled. The water drops are worn, and after a long time, the teeth will be broken. The most common injury is to grind a row of grooves at the root of the tooth.

4. The strength of brushing your teeth

What is the specific strength? A high-grade electric toothbrush will have an alarming power warning. In the case of a manual toothbrush, the bristles should be placed close to the teeth, and the tip of the bristles is bent by 1/3 and penetrates into the corners around the teeth. Similar to this feeling:

5. Brush up from the left or right?

If you are not left-handed, try to start from the right side of the tooth, because the right hand will be a little bit dirty when you touch the right side of the toothbrush, you need to pay more attention, so let's brush first.

This is not a joke. Many people have a little more tartar on the right side of the teeth than on the left side.

6. Brush the outside of the inside?

As for the inside and the outside, I have to brush it. I don't need to say this. The bacteria can pick up where it is the upper hand, and they grow 360 degrees seamlessly on the teeth. If you only engage in half health, it is self-deception.

7. Brush for two minutes so long?

Why is it at least two minutes?

The average person is not a wisdom tooth is 28 teeth, each tooth has 3 faces to brush, which is a total of 84 tooth faces, 120 seconds / 84 tooth faces, each face brush less than two seconds, this speed is fast enough It is.

In fact, for most people, if you want to achieve better brushing effect, two minutes may not be enough.
