牙齿美白（Teeth Whitening）

牙齿美白（Teeth Whitening） 牙齿美白(Teeth Whitening) Let's see why There are many reasons for the coloration and yellowing of the teeth. In general, they can be divided into two parts, namely, endogenous and exogenous. Exogenous tooth surface coloring is due to the existence of a variety of bacteria, they secrete a number of sticky substances, diet tea, smoke stains and water absorption of certain minerals in the viscous material, the teeth gradually become yellow or black. Endogenous coloring is formed during tooth development, such as tetracycline deposited in the dentin, could make the teeth become yellow, brown or dark gray, as tetracycline stained teeth; if too much fluoride in drinking water, may also lead to dental fluorosis, tooth surface is white chalk color, brown patches, if the tooth nerve necrosis and bacterial decomposition products also make teeth black. Coffee, tea, smoking and red wine are the culprits for exotic coloured teeth. According to statistics, China has 15% to 25% smokers, including female smokers, that is to say, China's 2~3 million teeth are yellow and black. The influence of coffee, red wine and tea on the teeth can not be ignored. Teeth whitening essence is a clear enamel on the tooth enamel and stain and pigment program. According to the depth of the tooth color, the reasons for the formation, should be taken in different ways to whitening. Effective folk prescription: cut with white papaya, wipe teeth 2 times a day, 2 minutes each time, insist on one month, must be effective Other information Nowadays, more and more people want their teeth to be white and jade, so many people choose to do some cosmetic work on their teeth. However, the beauty of the teeth should be based on the basic conditions of their teeth, choose the right way to get the best results. First of all, you should understand the reason why your teeth are not white enough. In medicine, pure tooth color, yellow, dark, etc. collectively referred to as tooth coloring. It is generally divided into two types: exogenous and endogenous. In brief, exogenous coloring refers to the external staining of teeth, mainly caused by food coloring and smoke stains. The endogenous coloring, it is because in the period of tooth development taking certain drugs or drinking water and other causes of tooth color anomalies are common tetracycline stained teeth and dental fluorosis. There are two general treatments for dental pigmentation: repair and bleaching. Method of repair is to grind a part of the natural teeth, covered in the corresponding parts with artificial materials, the utility model has the advantages of the color change is obvious disadvantage is to face the possibility of removing natural teeth and must wear and pulp complications. Tooth whitening treatment is a kind of natural teeth without removing the tooth color change treatment, such as many hospitals and dental clinic with whitening technology is one of them, it is through special cold light irradiation cover on the surface of teeth bleaching agent, to change the color of teeth to make short-term in the infiltration of dental hard tissue, the utility model has the advantages of no damage to tooth hard tissue, operation treatment time is about 30~45 minutes, but the shortcomings are due to bleaching drugs, the bleaching effect will be different because of individual teeth. Dentists generally have 4 suggestions for people who need to have teeth whitening: 1. go to a trusted medical institution. 2., mild discoloration of teeth, first try conservative treatment (bleaching) is appropriate. 3. severe tooth discoloration or change the color requirements of the higher people should not use bleach manner. 4. people who choose to repair the treatment should have a certain psychological expectation, such as the possibility of grinding away some natural teeth or hurting the pulp! Healthy teeth need to be taken care of from childhood Has more than 10 years of oral work experience of any doctor told reporters, now the tooth whitening products have made great progress. The earliest way to whiten teeth was to use high concentrations of hydrogen peroxide to remove the teeth. In mid 90s, the first foreign teeth bleaching products to enter the domestic time, any doctor in the hospital on the introduction of the product, after a period of time, many people have found that the use of the product cycle is too long (every day use, use period more than 1 months), a lot of people are difficult to adhere to, the effect of decolorization and teeth it is very general, therefore, this product in the domestic promotion for ten years, also failed to open the market. It is said that in the west, tooth whitening technology has been more than 100 years old, but it didn't mature until the 80s of last century. Now the new tooth whitening is whitening, this method in the United States carried out ten years, although the severe tetracycline tooth effect is not obvious, but compared to the original products, whitening effect is indeed improved. The key is the development of tooth tooth embryo, therefore, the mother during pregnancy and children in early childhood, the use of drugs should be careful, otherwise it will affect the development of enamel, causing unhealthy teeth and pigmentation. Uncover the truth about tooth whitening White and shining teeth are wishful thinking Experts say, Although the domestic tooth whitening market demand is very big, but we do not recommend consumers teeth whitening, because the current for domestic consumers, the protection of dental health is the most important, but, so far, the market has not yet appeared on an absolute to meet consumer demand for teeth whitening products. The anonymity of experts: because there are patients need, at the beginning of the Camry oral cavity is also teeth decolorization service, but this service has repeatedly caused patients dissatisfaction. The reason is that the teeth bleaching effect can not meet consumer expectations, many consumers want to post bleaching teeth, their teeth can be like a star teeth as white crystal, this is actually not very realistic, unless it is otherwise do KaoCiYa, now is not so obvious whitening products. Because there is always mention the views of patients, affecting the hospital's reputation, but only the appearance of the teeth whitening teeth to help, have no effect on dental health, so the teeth bleaching Camry simply stopped this business. Experts told reporters that the teeth bleaching is a major deal with acid treatment, or decalcification, at present, the market sales of teeth whitening products should be used is the decolorization method, using this method can make the yellow and black teeth color shallow, but after the teeth bleaching is not enough natural gloss, affected teeth beautiful. As for the allergic reaction caused by consumers to use tooth whitening products, is basically normal, because there are many nerve vascular middle teeth, using bleaching products will cause certain stimuli, such as sour, fear of cold, serious may cause gingival part hyperemia, swelling, discontinuation, these adverse reactions will disappear. However, the tooth whitening products should also be like drugs, express its components, and may cause a variety of adverse reactions, so that consumers understand before use, and in accordance with their own circumstances to choose. In comparison, we recommend that consumers are more willing to clean the teeth, in addition to remove plaque, tartar in the oral cavity, oral health protection, also can solve the color smoke and drink coffee caused mild teeth. Scaling including ultrasonic scaling and sandblasting two steps, sandblasting can improve the gloss of the teeth, the appearance of the teeth have some help. Many people are keen on teeth whitening, but so far only KaoCiYa can really achieve the purpose of consumers, but the high cost of porcelain teeth, installed before the need for a large area of grinding teeth, only suitable for dead teeth. Dental health is only pigmentation consumers do not have to spend money to suffer, so I urge everyone to straighten out the mentality, not to pursue the beauty of teeth. Yellow teeth, who is the enemy? The oral health standards issued by the WHO are: clean teeth, no dental caries, no pain, and normal gingival color. The authorities have been in the United States for workers over the age of 20 had a tooth whitening survey found that 81% of people want to have white teeth, 39% of people think that their teeth are not white, and willing to take measures for tooth whitening. There are many reasons for the coloration and yellowing of the teeth. In general, they can be divided into two parts, namely, endogenous and exogenous. Exogenous tooth surface coloring is due to the existence of a variety of bacteria, they secrete a number of sticky substances, diet tea, smoke stains and water absorption of certain minerals in the viscous material, the teeth gradually become yellow or black. Endogenous coloring is formed during tooth development, such as tetracycline deposited in the dentin, could make the teeth become yellow, brown or dark gray, as tetracycline stained teeth; if too much fluoride in drinking water, may also lead to dental fluorosis, tooth surface is white chalk color, brown patches, if the tooth nerve necrosis and bacterial decomposition products also make teeth black. Coffee, tea, smoking and red wine are the culprits for exotic coloured teeth. According to statistics, China has 15% to 25% smokers, including female smokers, that is to say, China's 2~3 million teeth are yellow and black. The influence of coffee, red wine and tea on the teeth can not be ignored. Teeth whitening essence is a clear enamel on the tooth enamel and stain and pigment program. According to the depth of the tooth color, the reasons for the formation, should be taken in different ways to whitening. Whitening teeth can be found Pay attention to "very beautiful teeth" in ancient Chinese, have a shiny white teeth has become one of the standards of modern beauty. Not only women, but also men who want to live in high quality, want to be whiter and healthier. Some people do not laugh at all times, afraid of exposing their black, yellow teeth. However, in the face of tooth whitening boom in different ways, such as whitening toothpaste, cleaning and bleaching, consumers often have no choice, which is a more suitable and effective? Dental treatment and whitening Teeth whitening, from a medical perspective is a kind of clean tooth enamel and dentin stain and pigment process. Harbin choose beauty medical out-patient department of dental Doctor Liu told reporters, resulting in black teeth, yellow and many reasons, generally divided into two kinds of endogenous and exogenous. It is because of the existence of various exogenous bacterial tooth surface, they produce a lot of sticky substances on the surface of the teeth, the tea stains, smoke stains, and some minerals in drinking water by adsorption in the viscous material in the diet, the teeth gradually become yellow or black. Endogenous formation during tooth development, such as tetracycline deposited in the dentin, could make the teeth become yellow or dark gray, as tetracycline stained teeth; if too much fluoride in drinking water, may also lead to dental fluorosis, dental plaque with tan. According to the depth of tooth color and the reasons for the formation of different ways, should be taken in different ways whitening. At present, the main application of the method are the following: whitening toothpaste, scaling, tooth bleaching, porcelain and currently the most popular white tooth paste. But no matter which method is adopted, the dental caries and periodontal disease must be cured, otherwise the disease will be aggravated. Whitening toothpaste does not work much There are various brands of whitening toothpaste sold in the mall. What's the effect? Professor Guo Wei of Shanghai Second Medical University School of Stomatology said that these whitening toothpaste basically can not play a big role, mainly through the inclusion of friction agents and teeth surface stains occur physical friction. Some brands of whitening toothpaste also add oxidant, but because of the content of chemical composition is little, general brushing time is short, so whitening effect is very small. If the original tooth color is black hair yellow, the use of whitening toothpaste and certain to maintain and promote the role; but if the tooth surface has obvious spots, or due to smoking, drinking tea in the teeth more yellow, with no effect of whitening toothpaste. Then the scaling effect how? Doctor Liu Xing said, in fact, is mainly used for whitening teeth, it is a kind of routine functional method, mainly for general dental calculus, plaque on the surface of the teeth. If there is a strong odontolith covered on the tooth surface, then take the scaling method is more appropriate. Also, regular cleaning, cleaning teeth and good brushing habits, the most fundamental way is whitening teeth. Don't bleach for more than 3 months At present the most commonly used whitening method or bleaching, it applies to a wide range of people and people over the age of 18 can apply. However, tetracycline teeth, dental fluorosis dentin has discoloration of teeth, using the ordinary method of bleaching is also very difficult to achieve a good whitening effect. The procedure for bleaching is this: first, make a denture base according to the shape of your teeth, and then put the bleach into the denture before going to bed every night, then wear it on your teeth. Bleach composition is generally 30% of the concentration of hydrogen peroxide, which is slightly acidic ingredients, with teeth on the formation of melanin reduction reaction, so that the teeth to restore the original color. This method is small risk, quick effect, no damage to the gums and pulp, as long as under the guidance of dentists, the whole process is safe and effective, generally need a month, the longest can not exceed 3 months. Dr. Liu said that some people feel the pain of the teeth during the bleaching process. They are sensitive to cold and hot. This is a normal reaction and will return to normal after the treatment is completed. At the same time, Dr. Liu also stressed that the effect of tooth bleaching is different for everyone. In order to achieve the best whitening effect, you can bleach a few times, but two or three times on the line, otherwise, there is still some damage to the teeth. The best way is not to use porcelain White teeth paste is the latest popular tooth whitening method, which attracts many people's attention because of its convenience and speed. Professor Guo Wei believes that the white teeth posted abroad has been popular for a long time, from the clinical practice is indeed effective, there is gradually replace the bleaching trend. But the white tooth paste also does not apply to tetracycline teeth, dental fluorosis dentin has discoloration of teeth. When it comes to porcelain, Liu Xing doctors think, it was for a tooth to have crack, such as the use of incomplete landscaping, if only to whiten the normal tooth small, cover with braces, or have a certain impact on the teeth. In addition, Professor Guo Wei also talked about the cause of dental pulp necrosis due to tooth trauma and other reasons, such as ordinary bleaching and whitening methods can not work, you need to open the pulp cavity for surgery. What is the correct way to brush your teeth? Brushing teeth is the most important way to remove plaque and prevent periodontal disease. Choose a well designed toothbrush to make it easy to rotate in the mouth. It can clean the food fragments in each part of the tooth and conform to the shape of the arch and the size of the tooth. General chooses springiness, smooth, easy sanding or nylon toothbrush to clean the hair ball. The length of brush head for adult toothbrush is 25 ~ 35mm, Width of 8 ~ 12mm, brush height 10 ~ 12mm, diameter 0.2 ~ 0.3mm, the number of rows of hair does not exceed 4 rows. The length of brush head for children's toothbrush is not more than 28mm, the width is not more than 11mm, the brushing height is 9 to 10mm, the diameter is not more than 0.25mm, and the number of rows of wool rows is not more than 3 rows. Adhere to the correct method of brushing teeth, brush plaque can be removed, but also gums massage. Healthy people usually brush their teeth 1~2 times a day, but people with gum or periodontal diseases should emphasize brushing sooner or later. After lunch, they should be added once, 3 minutes at a time. Correct brushing methods are short horizontal brush method and vertical rotation method. Short horizontal brush method (also called horizontal vibration method): horizontal brush method is used to people long seesaw action, the horizontal brush method with hard toothbrush will give periodontal damage (brush edge damage gums, gingival recession, cervical wedge-shaped defects etc.). Short horizontal brush method with short tremor of horizontal brush action, the most clean plaque, it is also known as ditch brushing. The brush tip and the tooth surface and gingival hairy at an angle of 45 degrees and mild pressure, brush the top portion into the gingival sulcus, and some in the ditch, and then to 6 ~ 8 times before and after the fibrillation fibrillation, brush mobile is only 1mm. When the upper and lower teeth of the upper and lower teeth are brushed, if the tooth arch is narrow, the toothbrush head can be erected as a short transverse brush to vibrate. At the same time, the teeth should be pulled and pulled together to clean the teeth, and to clean the occlusal gap of the occlusal surface. Vertical rotation method: can effectively remove plaque and soft dirt, and can stimulate gingival keratosis, and maintain the normal shape of the gums. The toothbrush face available wide bristles, a toothbrush can be, but the elderly, children or surgical periodontal disease should be used in hard or soft toothbrush. Brush lip buccal and posterior palatine surface action is parallel to the long axis of the bristles and the teeth, stick to teeth, the bristles pointing to the gingival margin, compression torsion toothbrush, the toothbrush bristles with 45 degree angle to the long axis, rotating toothbrush, namely the brush on the teeth along the tooth brush clearance downward brush, brush teeth when from the bottom to the brush. Note that the action is a bit slower, with a little tremor, the same part should be repeated 5~6 times. The same moves with the teeth brush tongue surface, narrow dental arch can be vertical part of hair toothbrush, pressure in the gum and teeth to pull down the crown and pull the brush, brush teeth occlusal surface. Because the toothpaste containing abradant and clean agent, they can in caries, anti-inflammatory, hemostatic, analgesic, anti acid, inhibition of calculus, reduce bad breath, so the use of toothpaste when brushing teeth can enhance the clean effect. Chinese oral therapy Yellow teeth are not sick, my tooth cut, the longitudinal section has three layers, the outermost enamel is slightly different, is that It differs from man to man., because each tooth calcification is different, some teeth is milky white, some are yellow, all of this is healthy. Many large yellow teeth are pathological, usually due to: 1, health factors: the teeth during development due to poor nutrition or illness, the calcification of the teeth affected, the teeth will be yellow Ersong crisp. 2, water quality factors: in some areas, especially in some mountain areas, due to high fluoride content in the water, excessive drinking fluoride teeth will yellow, and not 1-2 teeth, is full of big yellow teeth. The role of fluoride anti caries, so these people instead of prone to dental caries (decay). 3, drug factors: now most people know that tetracycline can lead to the occurrence of yellow teeth, especially in children (before age 5), taking greater impact. 4, health habits: some people do not pay attention to oral hygiene, no sooner or later brushing habits, a layer of the tooth surface accumulation of food debris, debris, calculus, smoke stains, tea stains etc.. These "yellow teeth" is not the teeth itself yellow, is not pay attention to oral hygiene caused. Treatment of yellow teeth are: in addition to pay attention to hygiene, proper brushing, go to the hospital to do a tooth bleaching, there are several kinds of tooth bleaching agent, the effect is good, but most of the high cost; light curing, is covered with a layer on the surface of the teeth and the teeth of similar color fat tree, and then use a special this light, beautiful, convenient, less cost, less firmly; conditional do porcelain teeth, porcelain veneer is best, can reach the real ones, is the ideal repair methods, disadvantages is to grind part of teeth, expensive. If the result of poor dental health can go to hospital for scaling (scaling), will play a very good effect, of course, is not a substitute for brushing. How to have white and beautiful teeth? If you want white, clean, healthy teeth, it will be helpful to choose the right tooth cleaning products. The face of a wide range of toothpaste, toothbrush, oral cleansing agent, you do not know how to choose. Here are some of the principles of choosing toothpaste, toothbrushes, and flossing. Toothbrush: build protect teeth, remove plaque of the first line of Defense Improving the selection of soft toothbrush. A soft toothbrush can effectively clean the teeth more than hard toothbrush, Bristles can also damage gums and teeth. The brand "head" toothbrush. The smaller the head of the toothbrush, the easier it is to clean the nooks and crevices of the mouth. Improving the timely replacement of the toothbrush. When the toothbrush bristles begin to flex outward, they should be replaced. You should always change your toothbrush at least three months. Improving the flu or cold after recovery should replace the toothbrush, to avoid re stained glass Which was to sign "Dental Association approved". Confirm the quality certification mark on the package. Dental floss: the second line of defense for building oral health. The brand is very necessary for the dental floss between the teeth clean, because there is often a source of gum disease. The utility model relates to an auxiliary tool for dental floss, which can help to fix the position of dental floss and make dental floss easier to clean to the gaps of teeth. Don't believe the brand of some type of dental floss more effectively. If you like one of them, just use it. Toothpaste: plays an important role in the prevention of fluoride in children and adults tooth decay, toothpaste is the best source of fluoride. Which was according to the American Dental Association (ADA) file, by the early decay fluoride can help repair tooth enamel in the tooth, and neutralize the acid production of dental plaque. Which was suitable for your toothpaste is not necessarily suitable for other people. If your doctor recommended a special toothpaste to you, such as anti allergy toothpaste or detergent toothpaste, they are not necessarily suitable for your family. Although the brand also claimed his slobber can kill the bacteria in the mouth. But the most important thing to prevent oral diseases is to remove bacteria from the periodontal pockets, but mouthwash does not penetrate them. Note: many of the brand products containing alcohol mouthwash slobber, some alcohol concentration is as high as 20% or even higher, this is a danger to children. The National Institute of dental and brain research believes high alcohol mouthwash is associated with oral cancer. Therefore, when buying mouthwash, you need to see clearly the instructions and whether the bottle top design takes into account child safety. Or choose an alcohol free variety. Which was if you want to have a white teeth, so teeth bleaching agent may attract you. But this bleach usually does not last long. Excessive use of bleach can also cause gum damage or infection, especially in degenerative or sensitive gums. So before you use bleach, consult a dentist to determine which product is best for you. In the last, the correct use of toothbrush and dental floss is also very important. Different people, different health conditions, different sizes of mouth, toothbrush and dental floss have different skills. In conclusion, oral health affects overall health. Therefore, be sure to master proper brushing skills and maintain the health of your teeth and gums - simple method With lemon juice, white teeth.. ... Method is as follows: Every night after brushing your teeth, rub some lemon juice with gauze to rub your teeth, and your teeth will become white and bright. Lemon clean and strong, and white effect, and contains vitamin C, can strong root. - Tips You can try to use [powder] Dentifrice is effective, get up early, before going to bed once the brush. It took about five to ten days to make a difference. Very effective. But if the color of your teeth is yellow Probably going to the dentist's office to ask for help. In these three methods is also good 1: cold light whitening: As time was to acid into the brain to go, should continue to limp home after three days! But there is a clear whitening effect. 2: whitening teeth pen: The front end of the utility model has a brush head, brushing on each tooth before sleeping, and waking up the next morning to wash off, and also has a good whitening effect. General dentistry has sold this Whitening Pen, and it and I just said whitening teeth are "Brite Smile" brand. 3: bailing plates clean g whitening dentifrice: The effect is good! In the dentist can do teeth whitening work around the following items: 1. - Ultrasonic scaling: The national health insurance scaling, mainly aimed at removing stone part of the tooth. Because the dental calculus is more likely to cause accumulation of dental bacteria, resulting in gingivitis, periodontal disease. So removing dental calculus is a medical practice. Of course, in the treatment at the same time, the tooth, neck, adjacent to the stone removed, and teeth will have whitening performance. Thick layer of stain, through ultrasonic scaling, you can also remove most; but with a concave hole, a groove in the teeth, or adjacent surface areas, dyeing is not easy to remove. 2. sausage cup with paste polish: This is the traditional form of tooth whitening. The paste is prophylaxis paste. It removes the stain on the smooth surface of the tooth. Restore the teeth to their original nature. But it still has no way to clean out the holes, grooves, and adjacent faces. - 3. Sand blast treatment of teeth: A dental sandblasting machine consisting of water, air, and particles, Air-powder, system, which eliminates all the staining on the surface of the teeth. It includes concave holes, grooves, and adjacent surfaces on the surface of the teeth. The particle used is Sodium Bicarbonate. The above method is mainly to remove the plaque on the teeth surface, dental calculus, and dyeing, and restore the original color of the teeth, and to achieve clean and whitening effect. If the tooth itself, texture and color change, I am afraid to use peroxide gas drugs in order to achieve the effect of teeth whitening. 4. active tooth bleaching: Use your individual teeth to bleach the tooth tray and put 10% of the bicarbonate peroxide on it. Keep it firmly on your teeth. As the effect of the drug grows, the color of the tooth fades and fades. The advantage is that the patient does it at home. The patient can decide on the number of teeth to bleach. The number of times to bleach, every time you bleach. And the end of all the treatment, the time to stop. Its drawback is: a longer course of treatment, about 2 weeks time, to achieve the whitening effect of patients generally want. In addition, the drug itself does harm to the teeth and to the soft tissues. It's better to do it under the guidance of a dentist. 5. plasma tooth whitening: It is similar to the use of peroxide drugs coated on the teeth surface, the group of plasma machine irradiation, activation, catalytic oxidation of the drug reaction, and to achieve the effect of tooth whitening. It takes about 1 hours each time and has to be done at a dental clinic. The total course of treatment is 3 to 5 times before the average patient can achieve whitening results. It is usually only the front row do, teeth, the buccal side of seoul. The center line of the upper, lower, left and right sides of each of the 4 or 16 teeth. 6. laser tooth whitening: It is the use of higher concentrations of bleach (H2O2 hydrogen peroxide), collocation appropriate laser dose, special catalytic catalyst, hydrogen peroxide bleaching effect enhancement, the teeth in organic pigments, from the carbon ring structure, bleached to hydrophilic pigment structure, and achieve the effect of safe whitening. In twenty-first Century, all speed, efficiency of you, I'm afraid it is your best choice. It's OK at a time. A course of treatment is about 3 hours. Similarly, it must be done at the dentist's office. Only do it, 16 teeth in front row, each side of a cheek. Although the use of hydrogen peroxide drugs, treatment of whitening teeth. More or less on their own teeth and teeth surrounding soft tissue damage, but are within the scope of control, do not have to worry too much. The discomfort of the teeth and the soft tissue can return to normal in about 3 to 6 days. * * for the sake of dentin, Oriental teeth had a little yellow, as long as it is not too serious, not necessarily "whitening". Many whitening products in the market use oxidizing agents to oxidize the dentin, and the teeth will become white in a short time. But after a period of time, the color usually goes back yellow
