as the saying goes, toothache is not a disease, but it hurts and kills people. Nevertheless, there are more and more people who need to see a doctor for dental diseases. One important reason is that some of the habits of loving and protecting teeth we have adhered to since childhood may be wrong!

error 1. Brushing teeth with cold water

cold water will cause toothache in people with dentin sensitivity, and is not conducive to the activity of effective substances in toothpaste. The main components of

toothpaste are friction agent and fluoride. Laboratory research found that the best temperature for these effective components to play a role is about 37 ℃.

suggestion: when brushing teeth, it is best to use warm water close to your body temperature.

error 2. Brush your teeth too hard

brush your teeth with too much force, which may hurt your teeth.

suggestion: 200 grams of force is enough, which is about the force of fingers picking up a popsicle and brushing teeth with the force of wrist instead of arm.

error 3. Brush your teeth horizontally

the survey shows that more than 90% of Chinese people brush their teeth horizontally. Brushing teeth is a physical wear on enamel.

the purpose of brushing teeth is to remove bacteria from the surface and gaps of teeth, not to damage the teeth themselves.

on the one hand, transverse brushing can not remove the garbage in the tooth gap. At the same time, it may also lead to wedge-shaped defect of tooth root, gum damage, dentin sensitivity and other problems.

suggestion: the correct way to brush your teeth is to brush vertically along the gap of your teeth.

error 4. Brushing time is too short

many people think that the purpose of brushing teeth is to remove food residues. In fact, it is not exactly so. Rinsing with water can remove more than 90% of food residues. The purpose of serious brushing is to eliminate dental plaque.

dental plaque is a colorless bacterium attached to the tooth surface and gum gap. It is the culprit of dental caries and gingivitis. The average time for Chinese people to brush their teeth each time is 59 seconds, which is not enough to completely clean their mouth.

suggestion: brush your teeth for no less than 2 minutes. Rinse your mouth first and moisten it, which is conducive to the action of the effective components in the toothpaste. Carefully brush it vertically from the front teeth, especially the places easy to be ignored such as the gap between teeth and the inside of teeth.

since the growth cycle of dental plaque is 12 ~ 24 hours, you should brush your teeth at least once every 24 hours even if you are away on business.

error 5. The brushing time is wrong

98% of Chinese people get up early to brush their teeth every day and then eat breakfast. As a result, the effective tooth protection ingredients in the toothpaste did not have much chance to stay on the teeth, but went to the stomach with breakfast.

suggestion: brush your teeth 20 minutes after meals. After getting up, rinse your mouth with water, eat breakfast and brush your teeth for 20 minutes after dinner. Especially after drinking acidic drinks or eating acidic fruits, it is best to brush your teeth after 20 minutes to avoid greater damage to the surface of your teeth.

error 6. There are too many mouthwashes after brushing

. Some active ingredients in toothpaste need to be retained on the surface of teeth to form a protective layer. Bacteria will not grow rapidly for a period of time. Excessive mouthwash will not have this effect. Some people will brush their teeth again with clean water, which is a foolish behavior to help bacteria hurt their teeth.

suggestion: one mouthwash for 10 seconds is enough. The experiment found that when we spit out the first mouthwash after brushing our teeth, 95% of the active ingredients are spit out, and 95% of the remaining 5% will be spit out in the second mouthwash.

so you can rinse your mouth once after brushing your teeth with toothpaste. Just rinse your mouth for about 10 seconds.

error 7. Dry mouth, staying up late and drinking less

will lead to high incidence of dental caries. Now people spend more time facing the computer and less time talking, and the secretion of saliva will be reduced accordingly.

saliva has the function of balancing oral ecology. After 11 p.m., people’s oral environment will begin to enter the drying period, and oral drying will breed bacteria.

suggestion: drink more green tea and water. In addition to replenishing water, green tea also contains fluoride to protect teeth from bacteria.

error 8. Brush clean only with a big tooth brush

everyone’s teeth are large and small. If the toothbrush is too large, it will not be flexible enough to perform tasks in the mouth. The toothbrush is too small to complete a large area of oral cleaning.

suggestion: choose a toothbrush of appropriate size. The size of the tooth head should be equal to the width of 2 and a half to 3 teeth.

the service life of a toothbrush should not exceed 1 month. The toothbrush head of the electric toothbrush should be replaced every 3 months. Because the power of the electric toothbrush is more mild and the design of the bristles is more conducive to tooth cleaning, the service life can be longer.
