Effective remedies: Wipe your teeth with white papaya slices twice a day for 2 minutes each time, which will definitely be effective in January.
Other information
Nowadays, more and more people want their teeth to be as white as jade, so many people choose to beautify their teeth. However, according to the basic situation of teeth, the best effect can be achieved by choosing the appropriate method.
First of all, you need to know why the teeth are not white enough. In medicine, simple yellow teeth and black teeth are collectively referred to as tooth color. Generally divided into exogenous coloring and endogenous coloring. Simply put, exogenous coloring refers to the "external coloring" of teeth, which is mainly caused by food pigment coloring and smoke stains. Endogenous coloring is caused by taking some drugs or drinking water quality during tooth development, such as tetracycline teeth and dental fluorosis.
There are generally two treatments for tooth coloring: restorative treatment and bleaching treatment. The method of restorative treatment is to grind some natural teeth and cover them with artificial materials. Its advantage is that the color of teeth changes obviously, but its disadvantage is the need to grind natural teeth and the possibility of complications caused by pulp injury. Tooth bleaching therapy is a treatment method to change the color of teeth without grinding natural teeth. For example, the cold light whitening technology recently adopted by many hospitals and dental clinics is one of them. It uses a special cold light source to irradiate the bleaching agent covering the tooth surface, so that it can penetrate into the hard tissue of the tooth in a short time to achieve the purpose of changing the color of the tooth. Its advantage is that it does not damage the hard tissue of teeth, and the treatment time is about 30~45 minutes. But the disadvantage is that the bleaching effect will be different due to the action of drugs.
For people who need to whiten their teeth, dentists generally have four suggestions:
1. Go to a trusted medical institution. 2. For moderately and slightly discolored teeth, it is recommended to try conservative treatment (bleaching). 3. People with serious tooth discoloration or high requirements for changing tooth color are not suitable for bleaching treatment. 4. People who choose restorative treatment should have certain psychological expectations, such as the possibility of grinding off some natural teeth or hurting dental pulp!
Healthy teeth need to be cared for from an early age.
Doctor Ren, who has worked in the oral cavity for more than ten years, told reporters that the current tooth whitening products have made great progress. The earliest method of tooth whitening is to decolorize teeth with high concentration of hydrogen peroxide. In the mid-1990s, when foreign tooth decoloring products just entered China, the hospital where Dr. Ren was located introduced this product. After using this product for a period of time, many people find that the service cycle of this product is too long (more than 1 month every day), and it is difficult for many people to stick to it, and the effect of tooth bleaching is also very general. So this product has been promoted in China for more than ten years, and it has not been able to open the market. It is said that tooth whitening technology has a history of 100 years in the west, but it didn't mature until the 1980s. At present, the relatively new tooth whitening method is cold light whitening, which has been implemented in the United States for more than ten years. Although the effect on severe tetracycline teeth is not obvious, the whitening effect is indeed improved compared with the original product. The key to tooth development is the embryonic period of teeth. Therefore, mothers should be cautious when using drugs during pregnancy and early childhood, otherwise it will affect the development of enamel and cause unhealthy teeth and pigmentation.
Uncover the truth of tooth whitening
White and shiny teeth are extravagant hopes.
Experts said that although there is a great market demand for tooth whitening in China, we do not recommend consumers to whiten their teeth, because the most important thing for domestic consumers at present is to protect their teeth health, and so far, there is no tooth whitening product on the market that can absolutely meet the needs of consumers. The expert, who asked not to be named, said: Because of the needs of patients, Mei Jia initially had a tooth bleaching service, but this service repeatedly caused patients' dissatisfaction. The reason is that the effect of tooth decoloration is difficult to meet the expectations of consumers. Many consumers want their teeth to be as white as those of a star after their teeth are discolored. In fact, this is very unrealistic. Unless it is porcelain teeth, no product has such a remarkable whitening effect. Because there are always complaints from patients, which affects the reputation of the hospital, and tooth whitening is only helpful to the beauty of teeth, but has no effect on the health of teeth, Camry simply stopped the business of tooth bleaching.
Experts told reporters that the main treatment method of tooth decoloration is acid treatment or decalcification treatment. At present, the tooth whitening products on the market should also use this decoloring method. After using this method, the color of yellow and black teeth can be lightened, but the luster of discolored teeth is not natural enough, which affects the beauty of teeth. As for the allergic reaction caused by consumers using tooth whitening products, it is basically normal because there are many nerve vessels in the middle of teeth. The use of decoloring products will cause certain irritation, such as sour taste, fear of cold, etc., which will seriously cause congestion and swelling of some capillaries in the gums. After stopping using, these adverse reactions will disappear. However, tooth whitening products, like medicines, should clearly indicate their ingredients and all kinds of adverse reactions that may be caused, so that consumers can know something before using them and choose according to their own conditions. Comparatively speaking, we prefer to recommend consumers to wash their teeth, which can not only remove dental plaque and tartar in the mouth and protect oral health, but also solve the mild tooth discoloration caused by smoking and drinking coffee.
Tooth cleaning includes two steps: ultrasonic tooth cleaning and sandblasting. Sandblasting can improve the gloss of teeth and contribute to the beauty of teeth. Many people are keen on tooth whitening, but so far only porcelain teeth can really achieve the purpose of consumers, but porcelain teeth cost a lot and need to be polished in a large area before installation, which is only suitable for dead teeth. Dental health is just pigmentation, so consumers don't need to spend money to suffer, so I advise you to keep a correct attitude and not to pursue the beauty of your teeth too much.
Yellow teeth, who is the enemy?
The oral health standards promulgated by the World Health Organization are: clean teeth, no dental caries, no pain, and normal gum color. The authoritative department once conducted a tooth whitening survey on American office workers over the age of 20. The results show that 8 1% people want to have white teeth, and 39% people think their teeth are not white enough and are willing to take measures to whiten their teeth. There are many reasons for tooth discoloration and yellowing, which can be roughly divided into two aspects, namely endogenous and exogenous. Exogenous coloring is due to the existence of many kinds of bacteria on the tooth surface, which secrete many sticky substances. Tea stains, tobacco stains in daily diet and some minerals in drinking water are adsorbed on these sticky substances, which gradually turn teeth yellow or black. Endogenous coloring is formed during tooth development. If tetracycline is deposited in dentin, it will turn teeth into yellow, brown or dark gray, which is called tetracycline teeth. If the drinking water contains too much fluorine, it may also lead to dental fluorosis, white chalk and brown plaque on the tooth surface. If tooth nerve necrosis is combined with bacterial decomposition products, it will also make teeth black. For exogenous colored teeth, coffee, tea, smoking and red wine are the main culprits. According to statistics, there are 15% ~ 25% smokers in China, including many female smokers, which means that 200 ~ 300 million people in China have yellow and black teeth. The influence of coffee, red wine and tea on teeth can not be ignored. Tooth whitening is essentially a process of removing stains and pigments from tooth enamel and enamel. According to the depth of tooth color and the causes, different ways should be taken to whiten teeth.
Tooth whitening can only be found
China paid attention to "teeth like scallops" in ancient times. Whether there are white and shiny teeth has become one of the criteria to measure modern beauty. Not only women, but also men who pursue a high-quality life want their teeth to be whiter and healthier. Some people don't dare to laugh at ordinary times, for fear of showing their black and yellow teeth. However, faced with different tooth whitening methods such as whitening toothpaste, tooth washing and bleaching, consumers often have no choice. Which is more suitable and effective for them?
Whitening after dental treatment
Tooth whitening, medically speaking, is a process of removing stains and pigments from enamel and dentin. Dr. Liu Xing, who chose dentistry in Harbin Beauty Clinic, told the reporter that there are many reasons for the blackening and yellowing of teeth, which are generally divided into endogenous and exogenous.
Exogenous is because there are many kinds of bacteria on the tooth surface, which secrete many sticky substances on the tooth surface. Tea stains, smoke stains in daily diet and some minerals in drinking water are adsorbed on these sticky substances, which gradually turn teeth yellow or black. Endogenous is formed in the process of tooth development. If tetracycline is deposited in dentin, it will turn teeth yellow or dark gray, which is called tetracycline teeth. If the drinking water contains too much fluorine, it may also lead to dental fluorosis and brown plaque on the tooth surface.
Different ways should be taken to whiten teeth according to the depth of tooth color and the reasons for its formation. At present, there are mainly the following methods: whitening toothpaste, tooth washing, tooth bleaching, porcelain and the latest popular whitening toothpaste. But no matter which method is adopted, it is necessary to ensure that both dental caries and periodontal diseases have been treated, otherwise these diseases will be aggravated.
Whitening toothpaste has little effect.
There are various brands of whitening toothpaste for sale in the shopping mall. What's the effect? Professor Guo Wei from the School of Stomatology, Shanghai Second Medical University said that these whitening toothpastes basically didn't have much effect, mainly because of the physical friction between internal friction agents and dental stains. Some brands of whitening toothpaste have also added oxidants, but because of the low chemical composition, the brushing time is short and the whitening effect is very small. If the original tooth color is not black and yellow, whitening toothpaste can be maintained and promoted to some extent; However, if there are obvious stains on the surface of the teeth, or if the teeth turn yellow because of smoking and drinking tea, whitening toothpaste will have no effect at all.
So what is the effect of tooth washing? Dr. Liu Xing said that in fact, tooth washing is not mainly used for whitening, but a conventional functional method, mainly aimed at calculus and plaque on the surface of ordinary teeth. If the tooth surface is covered with thick tartar, it is more appropriate to wash the teeth. Moreover, regular tooth washing, cleaning and developing good brushing habits are also the most fundamental methods to whiten teeth.
Do not bleach for more than 3 months.
At present, the most commonly used whitening method is bleaching, which is suitable for a wide range of people, above 18. However, for teeth with discolored dentin such as tetracycline teeth and dental fluorosis, it is difficult to achieve good whitening effect by using ordinary bleaching methods.
The procedure of bleaching is as follows: first, make a denture base according to the shape of the teeth, then put bleach in the denture base before going to bed every night, and then apply it to the teeth. The component of bleaching agent is generally 30% hydrogen peroxide, which is a slightly acidic component, and will have a reduction reaction with melanin on teeth to restore the original color of teeth.
This method has the advantages of low risk, quick response and no damage to gums and dental pulp. As long as it is carried out under the guidance of a dentist, the whole process is safe and effective, which usually takes one month, and the longest can not exceed three months. Dr. Liu said that some people feel toothache during bleaching and are sensitive to cold and heat, which is a normal reaction and will return to normal after treatment. Meanwhile, Dr. Liu Xing also stressed that the effect of tooth bleaching varies from person to person. In order to achieve the best whitening effect, it can be bleached several times, but it can only be bleached two or three times, otherwise it will still cause some damage to the teeth.
It is best not to use porcelain.
White toothpaste is the latest popular tooth whitening method, which has attracted many people's attention because of its convenience and quickness. Professor Guo Wei believes that white plaster has been popularized abroad for a long time, and it is really effective in clinic, and it has a tendency to gradually replace bleaching. However, white gypsum is not suitable for teeth with discolored dentin, such as tetracycline teeth and dental fluorosis.
Speaking of porcelain restoration, Dr. Liu Xing believes that it was originally used to beautify the teeth themselves, such as cracks and defects. If normal teeth are ground off just for whitening, and then braces are put on, it will still have a certain impact on teeth. In addition, Professor Guo Wei also talked about dental pulp necrosis caused by tooth trauma and other reasons. Ordinary whitening methods such as bleaching are not good, and pulp cavity surgery is needed.
How to brush your teeth correctly?
Brushing teeth is the most important means to remove dental plaque and prevent periodontal disease.
It is necessary to choose a well-designed toothbrush to make it easy to rotate in the mouth, remove food debris from all parts of teeth, and conform to the shape of dental arch and the size of teeth. Generally, choose a nylon toothbrush with elastic, smooth and easy-to-clean frosted or spheroidized hair. The length of the brush head of adult toothbrush is 25 ~ 35mm, the width is 8 ~ 12mm, the height of bristles is 10 ~ 12mm, the diameter is 0.2~0.3mm, and the number of rows of bristles does not exceed 4. The head length of children's toothbrush is not more than 28mm, the width is not more than 1 1mm, the bristle height is 9 ~ 10 mm, the diameter is not more than 0.25mm, and the number of bristle rows is not more than 3 rows.
Sticking to the correct brushing method can remove dental plaque and massage gums at the same time. Healthy people usually brush their teeth 1 ~ 2 times a day, but people with gum or periodontal disease should emphasize brushing their teeth in the morning and evening, and brush their teeth for 3 minutes every time after lunch. The correct brush method is short horizontal brush and vertical rotating brush.
Short transverse brush method (also called transverse vibration method): People are used to the transverse brush method of long saw action. If a hard toothbrush is added to this horizontal brushing method, it will cause damage to periodontal tissue (bristles will damage gingival margin, gingival recession, wedge-shaped defects in root and neck, etc.). ). short transverse brush method short vibration transverse brush action can clean dental plaque best, so it is also called in-groove brush method. Brush Mao Mao's nose and teeth? The gingival surface is slightly pressurized at an angle of 45, and the top part of the bristles enters the gingival sulcus, and the other part is outside the gingival sulcus, and then vibrates back and forth for 6 ~ 8 times. When it vibrates, the bristles only move 1 mm. When brushing the lingual surface and palatal surface of the upper and lower front teeth, if the dental arch is narrow, the toothbrush head can be erected for short-term horizontal brushing vibration. At the same time, the occlusal surface of the posterior teeth should be brushed and the pit and fissure of the occlusal surface should be cleaned. Vertical rotation method: it can effectively remove plaque and soft dirt, stimulate gingival keratinization and maintain the normal shape of gingiva. The choice of toothbrush is very wide, both hard toothbrush and medium hard toothbrush are acceptable, but the elderly, children or patients with periodontal disease should choose medium hard or soft bristle toothbrush after operation. The action of brushing the buccal and lingual surfaces of the back teeth is to make the bristles parallel to the long axis of the teeth and stick to the tooth surface, with the bristles pointing to the gingival margin, twist the toothbrush under pressure to make the bristles form a 45-degree angle with the long axis, and rotate the toothbrush, that is, brush the bristles down between the teeth when brushing the upper teeth, and brush them down when brushing the lower teeth. Be careful to move slowly, with a little tremor, and repeat the same part for 5 ~ 6 times. Brush the lingual and palatal surfaces of the front teeth with the same rotation as above. If the dental arch is narrow, the toothbrush can be pressed vertically, and a part of the hair bundle is pressed on the gum, which is brushed to the crown along the interdental space, and at the same time, the occlusal surface of the posterior teeth is brushed. Toothpaste contains abrasives and detergents, which can prevent caries, diminish inflammation, stop bleeding, prevent acid, relieve pain, inhibit tartar and relieve bad breath, so using toothpaste when brushing teeth can enhance the effect of cleaning teeth.

China dental treatment
Tooth yellowing is pathological. After tooth incision, there are three layers of tissue in the longitudinal section, and the outermost layer is enamel. It varies from person to person, and it is slightly different because of the degree of calcification of each person's teeth. Some people's teeth are ivory, while others are light yellow, which is healthy.
Many rhubarb teeth are pathological, generally due to:
1, health factors: during the development of teeth, due to malnutrition or illness, it will affect the calcification of teeth, and teeth will turn yellow and brittle.
2. Water quality factor: In some areas, especially in some mountainous areas, teeth with excessive fluoride will turn yellow due to the high fluorine content in water, instead of 1-2 teeth, which are full of rhubarb teeth. Fluorine can prevent dental caries, so these people are not prone to dental caries (tooth decay).
3, drug factors: Now most people know that tetracycline drugs can cause yellow teeth, especially children (before 5 years old).
4, hygiene habits: Some people do not pay attention to oral hygiene, do not have the habit of brushing their teeth in the morning and evening, and there is a layer of food residue, soft dirt, tartar, smoke stains, tea stains and so on. Accumulate on the surface of teeth. These "yellow teeth" are not caused by the yellowing of the teeth themselves, but by careless oral hygiene.
The treatment of yellow teeth is: besides paying attention to hygiene habits and brushing your teeth correctly, you should also go to the hospital for tooth bleaching. At present, there are several kinds of tooth bleach, and the effect is not bad, but most of them are expensive; Photocuring treatment is to cover the surface of teeth with a layer of resin similar to the color of teeth, and then use special light. This method is beautiful, convenient, fast, low cost and not very firm. If conditions permit, porcelain teeth can be made, preferably porcelain veneer, which is an ideal restoration method. The disadvantage is that the cost of grinding some teeth is high. If the oral hygiene is not good, you can go to the hospital to clean (wash your teeth), which will have a good effect. Of course, it can't replace brushing your teeth.
