1. Will you brush your teeth immediately after meals?
Brushing your teeth immediately after a meal will destroy the enamel. Brushing your teeth is a good habit. People who love teeth are used to brushing their teeth twice every morning and evening. But some people brush their teeth immediately after meals, and some people even brush their teeth no matter what they eat. In fact, it is not good for their dental health. A large number of acidic foods that people eat at meals will adhere to the teeth, which will soften the enamel on the surface of the teeth and even react with calcium and phosphorus molecules in the axial layer of the teeth, so that calcium and phosphorus are separated, and the teeth will become soft and brittle. Brushing teeth at this time will destroy enamel and damage tooth health.
Dentists suggest that you can rinse your mouth with water or drink a small glass of milk after meals or eating acidic food. Close contact with teeth with milk like gargling is helpful to clean the mouth, neutralize the acidity of food and accelerate the recovery process of calcium in teeth. The harm of food with high acidity to children's teeth can not be ignored. Parents must control the amount of candy their children eat. If you insist on brushing your teeth after meals, wait half an hour before brushing your teeth. At this point, the protective layer of your teeth has been restored, and brushing your teeth will not damage your teeth.
2. Common misunderstandings of brushing your teeth
(1) Brush your teeth sideways
According to the post, the survey shows that more than 90% people in China brush their teeth horizontally, which is a kind of physical wear on enamel. On the one hand, transverse brushing can't remove the rubbish between teeth, and at the same time, it may lead to wedge-shaped defect of root, gum damage, dentin sensitivity and other problems.
Suggestion:
The correct way to brush your teeth is to brush vertically between your teeth.
Expert comments:
Transverse brush is easy to wear enamel.
Horizontal brush is really not worth advocating. The dentist's advice is vertical brush. Because brushing your teeth horizontally is actually very difficult to brush your teeth, and it can't achieve the effect of thorough cleaning. The worse effect of transverse brushing is to wear the enamel of teeth, especially those who brush their teeth hard, which is easy to form "wedge wear" after a long time. Wedge-shaped wear is characterized by root wear and atrophy, which makes teeth loose and sensitive. Many people have toothache when they are dry in winter, which is caused by wedge-shaped wear.
Experts emphasize that you should brush your teeth vertically. If wedge-shaped wear has occurred, you can go to the hospital to repair it and fill the worn position with resin to avoid further damage to the teeth.
(2) Brush your teeth with cold water
According to the post, cold water can cause toothache in people with dentin sensitivity, and it is not conducive to the active substances in toothpaste. The main ingredients in toothpaste are abrasives and fluoride. Laboratory research shows that the optimum temperature for these effective components to work is about 37℃.
Suggestion:
It is best to brush your teeth with warm water close to your body temperature.
Expert comments:
(3) It is best to brush your teeth with warm water.
It is right to brush your teeth with warm water. Some people brush their teeth with cold water, which can cause dentin hypersensitivity and pain. Especially in winter, you need to brush your teeth with warm water to avoid dentin allergy. The temperature of warm water should be close to body temperature. Too hot water is not good.
(4) The brushing time is too short.
As mentioned in the post, many people think that the purpose of brushing teeth is to remove food residue. But in fact, the purpose of brushing teeth is to eliminate dental plaque. Dental plaque is a colorless bacterium attached to the tooth surface and gingival space, which is the chief culprit of dental caries and gingivitis. In China, the average time for people to brush their teeth is 59 seconds, which is not enough to thoroughly clean their mouths.
Suggestion:
Brush your teeth for at least 2 minutes. First, carefully brush vertically from the front teeth, especially in places that are easily overlooked, such as between the teeth and the inside of the teeth.
Expert comments:
(5) Brush your teeth for at least 3 minutes.
Brush your teeth for at least 3 minutes at a time to ensure that the tooth surface of each tooth is carefully brushed. As long as you brush your teeth carefully every time, brush your teeth twice every morning and evening. It is not necessary to brush your teeth after every meal, because it takes more than 12 hours for dental plaque to form and adhere to your teeth. Some people's way to protect their teeth is to brush their teeth frequently, which is actually unnecessary. Brushing your teeth too many times is easy to wear your teeth.
(6) Brush your teeth too hard
The post said that brushing your teeth too hard may hurt your teeth.
Suggestion:
The strength of 200 grams is enough, which is probably equivalent to picking up an popsicle with your fingers and brushing your teeth with the strength of your wrist instead of your arm.
Expert comments:
(7) The intensity of brushing varies from person to person.
It is also correct not to brush your teeth too hard. It is not that the greater the intensity, the more you can clean your teeth. If you brush your teeth in the wrong way, the greater the intensity, the easier it is to hurt your teeth. But the intensity of brushing varies from person to person, and there is no quantitative standard. Brush your teeth regardless of weight, it is advisable to brush them clean, and everyone can handle them according to their own situation.
Brush your teeth after getting up.
According to the post, 98% of China people get up early to brush their teeth every day, and then have breakfast. In this way, the effective tooth protection ingredients in toothpaste do not have much chance to stay on the teeth, but are eaten in the stomach with breakfast.
Suggestion:
Brush your teeth 20 minutes after meals. Rinsing your mouth with water after getting up, eating breakfast and brushing your teeth 20 minutes after meals are the healthiest, especially after drinking acidic drinks or eating acidic food.
Expert comments:
(9) There is nothing wrong with eating breakfast after brushing your teeth.
Brush your teeth in the morning and evening, but it is still inconclusive whether to brush your teeth before breakfast or after breakfast in the morning. At present, there is no medical opinion that it is not appropriate to brush your teeth after getting up in the morning. Now most people in China are used to brushing their teeth before breakfast, which is nothing wrong. As for the effective ingredients of toothpaste will be eaten in the stomach after brushing your teeth, this statement is not true. The function of ordinary toothpaste is cleaning. After brushing your teeth and rinsing your mouth thoroughly, there are actually no so-called "effective ingredients" on your teeth. If I don't brush my teeth before breakfast, I always feel that there is a foreign body in my mouth, which is not clean, and I don't feel at ease when eating breakfast. Brush your teeth and rinse your mouth after breakfast to remove food residue from breakfast.
(10) The toothbrush is too big.
Everyone's teeth are big and small, the toothbrush is too big, it is not flexible enough to perform tasks in the oral cavity, and the toothbrush is too small to complete large-scale oral cleaning work.
Suggestion:
Choose a toothbrush with the right size. The size of the toothbrush head should be equal to the width of two and a half to three teeth.
Expert comments:
(1 1) Replace the toothbrush every three months.
It is not recommended to use an oversized toothbrush, and the size of the toothbrush is appropriate to ensure that the brush head can flexibly extend to the rearmost teeth. If the toothbrush is too big, you can't clean the teeth without reaching the last part.
How to grasp the size of toothbrush? It is not accurate to say that the brush head is equal to the width of two and a half to three teeth, because what kind of teeth do teeth refer to? The size of front teeth and big teeth is very different. When you choose a toothbrush, it depends on whether the brush head can flexibly extend into the big teeth for cleaning.
Ordinary toothbrushes can be replaced once every three months, but toothbrushes with deformed bristles should be replaced immediately.
2, brushing steps need to know.
Step 1: Brush the outer surface of teeth first.
Put the bristles of the toothbrush at an angle of 45 degrees to the surface of the teeth, gently press them at the junction of the teeth and gums, and gently brush them back and forth in a small arc. The upper row of teeth brush down and the lower row of teeth brush up. Pay attention to brushing the gums lightly, and proper massage can promote their blood circulation.
The second step is to brush the occlusal surface of the teeth again.
Lay the toothbrush flat and brush the occlusal surface of the teeth back and forth with moderate force. The dynamic bristles of health toothbrush can play a unique role in cleaning the gap between teeth and the surface of teeth. The flexible and slender brush head makes the hard-to-reach posterior molars clean.
Step 3: Brush the inside of the teeth.
Put away your toothbrush. Use the dynamic bristles at the front of the toothbrush to gently clean the inner surface of the teeth up and down.
Step 4: Brush the surface of your tongue lightly.
Gently remove food residue and bacteria from the inside out. Keep your breath fresh.
