The process is as follows:
① Choose a soft-haired toothbrush, and point the toothbrush at a 45-degree angle with the long axis of the teeth to the root tip;
(2) Pressing the gingival-dental junction area to make one part of the bristles enter the gingival sulcus, and the other part spread out on the gingival margin, reaching into the adjacent gap as far as possible;
(3) Two brushes and ten horizontal brushes;
④ Brush the buccal side with the same hand and the lingual side with the opposite hand;
⑤ lingual and palatal surfaces of anterior teeth: brush up and down;
⑥ Tooth chewing surface: brush before and after;
⑦ Brush above and brush below;
8 Brush your teeth to "cover everything".
In addition, we must also avoid several common mistakes when brushing our teeth:
Mistake one,
Brush your teeth with cold water
Cold water can cause toothache in people with sensitive dentin, and it is also not conducive to the active substances in toothpaste. The main components of toothpaste are abrasives and fluoride. Laboratory studies have found that the optimum temperature for these effective components to work is about 37 degrees Celsius.
Suggestion: It is best to brush your teeth with warm water close to your body temperature.
Mistake two,
Brush your teeth hard
Brushing your teeth too hard may hurt your teeth.
Suggestion: 200 grams of strength is enough, which is roughly equivalent to picking up an popsicle with your fingers and brushing your teeth with the strength of your wrist instead of your arm.
Mistake three,
Brush your teeth sideways.
Brushing teeth is a kind of physical wear on enamel.
The purpose of brushing teeth is to remove bacteria from the surface and crevices of teeth, not to damage the teeth themselves. 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.
Error 4,
The brushing time is too short.
Many people think that the purpose of brushing teeth is to remove food residues, but it is not entirely true. Rinsing your mouth with clear water can remove more than 90% of food residues, and the purpose of brushing your teeth carefully is to eliminate dental plaque.
Suggestion: Brush your teeth for at least 2 minutes. Rinse your mouth first. Moisturizing is beneficial to the effective ingredients in toothpaste. Carefully brush it vertically from the front teeth, especially in places that are easily overlooked, such as between the teeth and the inside of the teeth.
Because the growth cycle of dental plaque is 12-24 hours, you should brush your teeth at least every 24 hours even if you are on a business trip.
Mistake five,
Wrong time to brush your teeth.
Get up early to brush your 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. Rinse your mouth with water after getting up, eat breakfast and brush your teeth for 20 minutes after meals. Especially after drinking acidic drinks or eating acidic fruits, it is best to brush your teeth after 20 minutes, so as not to cause more damage to your teeth.
Mistake six,
Rinse your mouth too much after brushing your teeth.
Some effective ingredients in toothpaste need to be left on the surface of teeth to form a protective layer, so that bacteria will not grow rapidly for a period of time, and too much mouthwash will not have this effect. Some people will brush their teeth again with clean water, which is a foolish act to help bacteria hurt their teeth.
Suggestion: 1 mouthwash 10 second is enough. The experiment found that when we spit out the first mouthwash after brushing our teeth, 95% of the effective ingredients were spit out, and the remaining 5% was spit out in the second mouth.
Therefore, it is enough to rinse your mouth once after brushing your teeth with toothpaste, and the rinsing time is about 10 second.
Error 7,
Stay up late and drink less water.
These conditions will lead to a high incidence of dental caries. Now people spend more time in front of the computer, less time talking, and the secretion of saliva will be reduced accordingly.
Saliva can balance the oral ecology. After 1 1 pm, people's oral environment will begin to enter a dry period, and oral dryness will breed bacteria.
Suggestion: Drink more green tea and water. Green tea can not only replenish water, but also contain fluoride, which can protect teeth from bacteria.
Error 8,
Clean with a big toothbrush.
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.
The method of brushing teeth in different parts of the inner surface of the mouth is different. It is recommended to choose a toothbrush with soft bristles and small brush head. The specific method is as follows: 1. Upper tooth surface: rotate the toothbrush up and down at an angle of 45, brush about 2 teeth at a time, brush from top to bottom at a time, and do not brush horizontally, and it is appropriate to brush every 2 toothbrushes 10; 2, the inner surface of the upper teeth: similar to the brushing method of the upper teeth, special attention should be paid to brushing the front incisors, so that the toothbrush is vertical and brushed from top to bottom; 3, the lower tooth surface: similar to the upper tooth surface brushing method, or rotating brushing, but should be brushed from bottom to top to fully remove the food left on the tooth surface; 4, the inner surface of the lower tooth: similar to the brushing method of the upper tooth surface, because the inner surface of the lower tooth is prone to dental disease, so be sure to pay attention. Should the toothbrush stand upright, brush from bottom to top, or use the method of rotating brush.
Last time I attended a lecture on teeth, experts said that the most correct way to brush teeth is to squeeze out Geelong's natural toothpaste and apply a thin layer of about 1g on the toothbrush. The toothbrush is head-down, starting from the innermost part of the mandibular teeth, with bristles facing down, and rotating at a 45-degree angle from bottom to top for 65,438+00 times. Brush back and forth in front of the occlusion of teeth, close to the inside of teeth and tongue, brush carefully, and rotate the brush 10 times from bottom to top.
There are many correct ways to brush your teeth, and the one that suits you is the best. The so-called fitness for yourself means that for yourself, the skills are easy to master, you can brush your teeth easily and skillfully, massage your gums effectively, and keep your mouth clean and healthy. Pap brushing method is also recommended by dentists: the bristles of the toothbrush make an angle of 45 degrees with the long axis of the tooth, and the tips of the bristles point to the root tip of the tooth, that is, the upper teeth are up and the lower teeth are down. Gently press the bristles, but don't bend them, so that the bristles partially enter the gingival sulcus, and gently vibrate in the gingival sulcus for 4-6 times at a short distance from front to back, without leaving the gingival sulcus, and then rotate the toothbrush along the tooth surface towards the crown to clean the whole tooth surface. Similarly, brushing teeth in the lower area can effectively clean the gingival sulcus and neck, massage and stimulate the gums, but it takes a long time and is difficult to master.
1
Brush the outer surface of the teeth first.
First of all, hold the toothbrush well, and the angle between the teeth and the toothbrush should be 45 degrees. Gently put it between the gums and teeth, and then brush your teeth in a rotating way. All teeth should be brushed gently.
2
Then brush the occlusal surface of the teeth.
The method of brushing teeth on the occlusal surface is relatively simple, as long as we follow the usual sawing method and the included angle between toothbrush and teeth is 90 degrees when brushing teeth.
three
Brush the inside of your teeth again.
Stand the toothbrush upright and brush it gently with the bristles in front of the toothbrush, with the upper teeth brushing from top to bottom and the lower teeth brushing from bottom to top.
four
Finally, brush the surface of the tongue
Many people neglect to clean their tongues. In fact, brushing your tongue after brushing your teeth can effectively remove food residues and reduce bacteria, which is very helpful to prevent bad breath.

Brush up and down!
