In daily life, people brush their teeth every day, but a considerable number of people do not know how to brush their teeth, so it is extremely important to learn to brush your teeth correctly to maintain personal oral hygiene. The role of brushing teeth Brushing is the main method to keep the oral cavity clean, it can eliminate the soft white dirt, food debris and part of the plaque in the oral cavity, and has the role of massage gums, so as to reduce the pathogenic factors in the oral environment, enhance the ability of tissue resistance to disease, brushing teeth for the prevention of various oral diseases, especially for the prevention and treatment of periodontal disease and caries, has an important role. The good way to brush teeth 1, vertical brushing method is to put the tip of the toothbrush hair bundle at the junction of the gums and the crown of the teeth, with slight pressure in the direction of the teeth, brush downward when brushing the upper teeth, brush upward when brushing the lower teeth, and brush both the inner and outer sides of the teeth and the occlusal surface. Brush several times in the same area. This method can effectively eliminate plaque and soft scale, and can stimulate the gums to keep the gum shape normal. 2, chattering method refers to brushing the toothbrush bristles at an angle of 45 degrees to the teeth, so that part of the toothbrush bristles enter the gap between the gum and the tooth surface, and the other part reaches into the gap between the teeth, doing a short distance of chattering back and forth. When brushing the occlusal surface, the bristles should be placed flat on the tooth surface, making short back and forth tremors. You can brush 2-3 teeth in each part. Brush both the inner and outer sides of the teeth. This method is also horizontal brushing, but because it is a short horizontal brushing, the bristles are basically in the original position for horizontal chattering, compared with the large horizontal brushing, it will not damage the neck of the teeth and is less likely to damage the gums. 3. The physiological brushing method means that the tip of the toothbrush bristles are in contact with the tooth surface and then brushed gently toward the gums. This method stimulates the gums slightly as food passes through the gums and promotes blood circulation to the gums, which helps to keep the periodontal tissues healthy. In short, brush your teeth gently, not too hard, but repeatedly. Every side of the teeth should be brushed, especially the most backward molars, make sure to reach the toothbrush in and brush. If the previous methods are applied in combination, the results will be better. Every time you brush your teeth, if you are not sure, you can also look in the mirror to see if it is clean, only if you take it seriously, you can ensure the effect of brushing your teeth. Technical points of brushing 1. Identify the attachment site of plaque: This is a very important part of the brushing effect. The plaque display is a reliable way to identify plaque. 2, brush bristles close to the tooth surface: the anatomical structure of the mouth is complex, and there are more uneven areas, especially the adjacent surface of the teeth and the far middle surface of the last molar, which are the most likely to accumulate plaque. When brushing the far middle surface of the molar, from a direction or from a different direction, angle, try to put the bristles into and close to the tooth surface, before it is possible to make a clear brush. 3, the action of the toothbrush head: oral structure is more complex, only one brushing method, a brushing action, is difficult to go to the net plaque in the mouth. When people brush their teeth, the basic action of the toothbrush head has four kinds of longitudinal, horizontal, rotating and chattering, usually four kinds of action mixed to complete the brushing process. 4, sequential proficiency in the above-mentioned brushing methods: on the basis of proficiency can also be integrated, for example, first for the horizontal chattering method, and then for a few vertical chattering method, choose their advantages to maintain oral hygiene. Brushing water Before brushing, do not dip the toothbrush in water, and do not rinse your mouth with water, water will make the toothbrush toothpaste teeth friction reduced, it is best to use warm water (water temperature of about 35 ℃ water) when brushing teeth. If you do not pay attention to the water temperature when brushing or rinsing, long-term brushing with cool water, there will be gum recession, loose teeth fall off and other phenomena. Warm water brushing can also effectively reduce the irritation of toothbrush bristles on gums and effectively avoid bleeding of gums. Frequent stimulation of teeth and gums with sudden cold and heat may lead to various diseases and shorten the life span of teeth and gums. The life span of teeth is shorter than that of the human body, and the root cause is the habit of “brushing teeth with cold water”. Brushing the three misconceptions 1, mouthwash every day, cool and clean Correct: mouthwash is not advocated for daily use, the use of pharmaceutical mouthwash in the hospital more to follow medical advice. Many people think that mouthwash is convenient and useful, after brushing the mouth feels cool and clean. In fact, mouthwash is not advocated for daily use and long-term use. Because the oral cavity also has a number of flora communities, these flora balance to effectively prevent the occurrence of various oral diseases. Now some mouthwash, especially in the hospital doctors to patients prescribed mouthwash contains anti-inflammatory ingredients, anti-inflammatory ingredients often inhibit a certain type of oral flora, another flora relatively increased, resulting in oral flora imbalance. For example, too many anaerobic bacteria in the mouth will induce periodontitis, more likely to form tartar, and too many lactic acid bacteria will cause dental caries. Therefore, mouthwash should not be used frequently for a long time, the use of medicinal mouthwash is best to follow medical advice, after the oral inflammation is cured, it is best not to use medicinal mouthwash as a daily care products, the best oral care or daily adhere to the brush. 2, brushing straight up and down for a short duration Correct: you should keep the toothbrush and teeth at an angle of 45 degrees, and each position should be brushed lightly at least 10 times. The correct way to brush teeth should be the toothbrush and teeth at an angle of 45 degrees, brush lightly up and down, brush lightly in front of and behind the teeth bite, each brushing position should be brushed at least 10 times, each brushing time lasts at least 3 minutes, so as to thoroughly and effectively remove oral bacteria, for some difficult to remove parts can also use mouthwash and dental floss with cleaning. Hu Xiaomin said, “Brush at home can watch the time themselves, if the brushing time is too short, brush is equal to white brush.” 3, women can not brush their teeth during the month Correct: pregnancy and postpartum nutrition sufficient and less exercise, gingivitis more frequent, should adhere to daily brushing with warm water. “Many people think that pregnant women have just given birth and are afraid of the cold during the month, it is best not to brush their teeth, in fact, this is a big misconception.” Hu Xiaomin said that gingivitis occurs more frequently during pregnancy because the gums react more intensely to the stimulation of plaque due to hormonal influences. Pregnant women should have oral examinations before pregnancy and undergo cleaning treatments such as scaling to prevent the occurrence of gingivitis during pregnancy and to prevent the spread to young children. In addition, women are more prone to gingivitis, periodontal disease and other oral diseases after giving birth because the hormone level in their bodies has not fully returned to normal, coupled with adequate nutrition and reduced exercise during pregnancy, the mouth is prone to congestion, and if not cleaned. Even during the month, pregnant women should insist on brushing their teeth with warm water every day. Bad effects caused by incorrect brushing Tartar stimulation Because of infrequent brushing, the plaque attached to the teeth gradually forms tartar, which will constantly stimulate the gums and can cause inflammation and bleeding of the gums. Stimulation of cavity After the dark brown cavity is formed by tooth decay near the gum, the edge is uneven and sharp, which often stimulates the gum to ulcer and cause bleeding. When periodontal disease occurs around the teeth, the main symptom is gum edema, inflammation, neovascularization and expansion, which often causes bleeding when chewing or brushing teeth. If periodontal disease develops into alveolar abscesses or loose teeth, gum bleeding is more likely to occur. These are the most common local causes of gum bleeding. There are also some systemic diseases that can cause gingival bleeding. For example, hematologic diseases, including various types of leukemia, hemophilia, thrombocytopenic purpura, aplastic anemia, and granulocytopenia. Some tumors growing on the gums, including those metastasized to the gums from other parts of the body, are also found to be extremely prone to bleeding in clinical practice. Certain diseases such as liver cirrhosis, hypersplenism, and late nephritis can cause low blood clotting or severe anemia due to vitamin C deficiency, and gum bleeding can also occur. For those who have gum bleeding caused by these systemic diseases, they should go to the hospital for examination and treatment as soon as possible. In addition, some women may have gum bleeding during puberty or pregnancy due to changes in endocrine regulation, which can mostly heal on their own after this period and generally do not require special treatment. Gum bleeding, first of all, you should go to the hospital to find out the cause of bleeding, caused by periodontitis, gingivitis need to go to the Department of Dentistry for treatment, while strengthening oral hygiene; such as systemic diseases caused by gum bleeding should be early to the Department of Internal Medicine for examination, a clear diagnosis, while the oral application of 1% to 3% hydrogen peroxide solution rinse mouth, to prevent oral infection and prevent bad breath caused by bleeding. Brushing posture Although brushing is something people have to do every day, it is not common to see people who really brush their teeth correctly. This brushing method can remove some of the dirt on the teeth, but it is easy to bruise the teeth and the surface of the teeth, which will lead to gum recession and root exposure in the long run. The correct way to brush your teeth is to brush in the direction of tooth growth by placing the toothbrush flat in the mouth, pressing the bristles lightly against the edge of the gums, and then gently turning your wrist to gradually turn the bristles to the tooth surface, brushing the upper teeth from top to bottom and the lower teeth from bottom to top, repeatedly. Brush the upper teeth from top to bottom and the lower teeth from bottom to top, repeatedly. Brush each area 5 to 10 times back and forth, so as to clean the surface of the teeth and the gaps, but also to massage the gums properly. After brushing the outside, brush the inside. The inside of the teeth is the easiest place to hide stains. When brushing the inner surface of the upper and lower front teeth, you should brush the toothbrush vertically, lifting it up and down along the teeth, and when brushing the occlusal surface of the large teeth (molars) at the back, you should brush it back and forth horizontally. Many people believe that brushing should not take less than 3 minutes. However, the latest research shows that the scientific brushing time should be 2 minutes and 1.5 Nm of force. Brushing for too long and with too much force does not result in cleaner teeth, but instead may damage the protective coating of the teeth and cause permanent damage to the teeth. The latest issue of Clinical Periodontology in the UK published the results of a trial conducted by Theismann at Newcastle University. They conducted a 4-week study of 12 people who took 16 different brushing styles, brushing for 30 seconds to 3 minutes and with a force of 0.75 to 3 Ng. Computer records were analyzed for their brushing patterns and tartar before and after brushing. The results showed that tartar decreased with increasing time and force of brushing, but when brushing time exceeded 2 minutes and force exceeded 1.5 Nm, tartar no longer decreased accordingly. Sisman said that brushing for too long and with too much force does not make teeth cleaner, but rather increases the likelihood of damage to the protective coating of teeth. If the toothbrush has a small contact area, he said, the pressure will be high even though the force is not too strong. Ordinary people should consult their dentist if they have difficulty determining how hard to brush their teeth. Please select a good tool for brushing teeth: (1) Small brush head, flexible rotation in the mouth. (2) reasonable arrangement of bristles, usually 2 to 3 rows, easy to clean teeth and brush teeth after the toothbrush itself cleaning. The bristles are made of high-quality nylon wire, fine and flexible. (3) The tip of the bristles is rounded, so it is not easy to damage the teeth and gums when brushing. (4) Gum recession requires an interdental brush. (5) In addition, the folklore method of adding strong tea to fix teeth is also a wonderful way to expand teeth. The practice is: use the lower and middle tea leaves to make strong tea, and use it to rinse your mouth after each meal, so that the food debris left in the teeth naturally off, without toothpicks to pick teeth. (6) Electric toothbrush, which has now become increasingly popular. Its benefits include: massaging the gums incorrectly brushing our teeth makes our gums often suffer. The slight vibration produced by the electric toothbrush rotating at high speed not only promotes the blood circulation in the mouth, but also has an unexpected massage effect on the gum tissue. Reducing the damage of brushing too hard and pull-saw horizontal brushing can cause damage to teeth and gums. Experiments have shown that electric toothbrushes can reduce the brushing force by about 60%, reducing gingivitis and gum bleeding by 62% and making the brushing process safer and more effective. Authoritative electric toothbrush brands include Braun Oral B, Crest, etc.
