If the body lacks calcium, the teeth will loosen and form dental caries. Vitamin D can promote the absorption of calcium and phosphorus, and vitamin A can also increase the antibacterial effect of gingival mucosa, so we should pay attention to ensuring the supply from the diet. In addition, fluoride is also very important to the health of teeth, and if it is lacking, it will easily lead to dental caries.
What foods can prevent dental caries?
Fish, rice, lentils, peas and broad beans have high phosphorus content, and phosphate can form a buffer system to prevent excessive acidification of the mouth. Children should eat more foods rich in calcium, such as beans, bean products, vegetables, fish and shrimp. So as to provide enough minerals and vitamins for the normal development of teeth.
Milk and dairy products contain a lot of calcium, which can inhibit the acid production of bacteria and prevent the dissolution of calcium and phosphorus compounds in teeth. In addition, immunoglobulins and enzymes contained in milk can inhibit the growth of bacteria in the mouth.
Foods containing more fluorine include fish, shrimp, kelp, jellyfish, tea and mineral water. Fluorine can form insoluble fluorapatite with calcium and phosphorus compounds in dentin, thus preventing the acid produced by bacteria from eroding dentin.
You should eat more foods that are not overcooked, because they contain more fat-soluble vitamins and minerals and need more chewing power when eating. Chewing can promote saliva secretion, help digestion and clean teeth. You should eat less refined food (such as plum, chocolate, soda, candy, cakes, biscuits, etc.). ).
Fruits, such as apples, pears, etc., can play the role of mechanical scrubbing of teeth when eaten, and wipe off bacteria attached to the surface of teeth. In addition, pectin in fruits can also inhibit bacteria. Vegetables contain many trace elements and a lot of vitamin C, and are also very important anti-caries nutrients. Plant fiber can reduce the adhesion of food and the formation of dental plaque through mechanical friction cleaning of tooth surface and secretion of salivary glands. In addition, vegetable oil can form a hydrophobic layer on the surface of teeth to protect teeth and prevent dentin from dissolving.
Oral care mainly includes personal care, professional care and social care. The technical term of tooth cleaning is tooth cleaning, which is an important part of professional health care. Because neither brushing teeth nor gargling can remove calculus, which is the main cause of gingivitis, it is necessary for doctors to remove calculus through scaling. In addition, dental plaque is the main cause of dental caries and periodontal disease, and scaling can also remove dental plaque, so tooth washing is necessary. It is generally considered that it is appropriate to wash your teeth once every six months to one year.
1 m: 45-degree angle brush method
It is particularly important to use correct brushing methods to prevent dental diseases. Oral care experts recommend brushing your teeth every day after meals, and each brushing must last for 2-3 minutes.
* Correct brushing angle and action Put the toothbrush bristles at an angle of 45 degrees with the tooth surface, gently press them at the junction of teeth and gums, and gently rotate them in a small arc. The upper row of teeth brush down from the gum, and the lower row of teeth brush up from the gum.
* Brush the inside and outside of your teeth. Remember to clean the inside and outside of the upper and lower teeth. When brushing the inside of the front teeth, stand the toothbrush upright and clean the teeth with power bristles.
* Brush the occlusal surface of teeth with moderate intensity, brush the occlusal surface of teeth in the front and back direction, and use bristles to penetrate into wisdom teeth to clean the parts that are difficult to brush.
Number 2: Automatic brushing is more fun.
Compared with ordinary manual toothbrushes, electric toothbrushes can completely remove 38% of dental plaque. At the same time, the slight vibration caused by the high-speed rotation of the electric toothbrush can not only promote the blood circulation of the oral cavity, but also have a very good effect on the gingival tissue, achieving good dental care and gingival protection. In whitening, electric toothbrush can effectively reduce tooth stains caused by drinking tea and coffee and poor oral conditions, and restore the original color of teeth.
Third: the softer the toothpaste, the better.
Choosing toothpaste should focus on two points: first, it contains fluorine, because long-term use of toothpaste containing fluoxetine formula can effectively prevent tooth decay; Second, it depends on what raw materials are used for the abrasive of toothpaste, because rough abrasive will wear enamel. Long-term use of toothpaste containing coarse abrasive is not good for teeth.
Generally speaking, the paste of toothpaste is frozen, and its texture is fine and smooth. Usually, high-grade silicon is used as abrasive, which has less wear on enamel. You can also brush different toothpaste on the new CD box five or six times to see if there are any scratches. Toothpaste without scratches has good abrasiveness. & gt
Question 2: How to prevent tooth decay most effectively? Cultivate good eating habits. Every time you eat and drink water, the minerals on the surface of your teeth will be lost, causing the chance of tooth decay. The more times you eat and drink, the greater the chance of tooth decay. Therefore, the breakfast, lunch and dinner should be timed and have enough weight, avoiding eating outside the main meal to reduce the frequency of eating and drinking, and drinking water only when thirsty, which can reduce the chance of tooth decay. If you are really hungry between meals, you can have tea once. Brush your teeth with fluoride toothpaste in the morning and evening Fluoride can strengthen your teeth and make them less susceptible to acid erosion. Fluoride can also help the lost minerals return to your teeth and restore the original tooth decay. Therefore, you should get up every morning and brush your teeth with fluoride toothpaste before going to bed at night. Check your mouth regularly every year. Check your mouth at least once a year, find tooth decay as soon as possible, and receive treatment to prevent tooth decay as needed, such as applying dental caries preventive. Treatment: the decayed tooth is not big, and the tooth is filled when it is still strong. If the decayed area becomes extensive and the teeth are already fragile, insert an artificial crown. Tooth decay spreads to the pulp: there are obvious cavities in the teeth, causing severe pain. Dental pulp may be infected by bacteria and die, and bacteria may even spread from dental pulp through root to nearby periodontal tissue, causing inflammation or abscess. Dental pulp treatment (root), if necessary, artificial crown will be installed. If the dentist thinks it is not suitable for endodontic treatment, the tooth should be extracted. Tooth decay is the most common disease of human beings. Among primary school students in Taiwan Province Province, the rate of tooth decay is as high as over 90%. The tooth decay rate of adults is also above 95%. Therefore, it is no exaggeration to call tooth decay the most common disease of human beings. Treatment of tooth decay Before filling the hole in the tooth, local anesthesia can be given to the tooth when necessary to reduce the pain that may occur during the treatment. During the treatment, the dental caries were cleaned with high-speed and low-speed mobile phone drill needles, and then filled with composite materials. Due to aesthetic factors, composite resin is usually suitable for anterior teeth. The back teeth are usually filled with silver powder. Silver powder has been used in clinic for decades and is the most convenient, economical, safe and effective filling material. For aesthetic reasons, the posterior teeth can also be filled with composite resin. However, the application conditions of composite resin are strict, and not all teeth can be applied. When the cavity of decayed teeth is too large, which endangers the dentin of residual teeth, we should consider using crown or casting metal crown or ceramic crown to restore teeth to avoid the fracture of residual teeth. Tooth decay can be prevented, because tooth decay can occur as long as there are teeth. Therefore, the filled teeth may still be decayed. The occurrence of tooth decay must have enough bacteria that can cause tooth decay attached to the tooth surface, and at the same time, there must be sugar for bacteria to produce strong acid to corrode teeth. If bacteria can be reduced to the surface of teeth and sugar can be reduced to bacteria, tooth decay can be prevented. Therefore, brushing teeth correctly with fluoride toothpaste after meals and before going to bed, and flossing to remove dental plaque between teeth can reduce the adhesion of bacteria on the tooth surface. Not eating snacks between meals will reduce sugar supply, and bacteria will produce strong acid to corrode teeth. In addition, regular oral examination can find and treat tooth decay at an early stage, with the best effect. Using pit and fissure sealant to seal the occlusal surface of caries-prone posterior teeth can also effectively reduce the caries of posterior teeth. Applying fluoride to the whole mouth once every six months can also enhance the resistance to tooth decay. First of all, let's learn what tooth decay is. Tooth decay, sometimes called worm tooth, is scientifically called dental caries. The main reason is dental plaque. Dental plaque is an almost colorless film on the surface of teeth, which contains bacteria that cause dental caries. After each meal, these bacteria in dental plaque will react with sugar or starch in food to produce acidic substances that corrode teeth. Over time, the tooth enamel will be destroyed, forming a fragile cavity. If it continues to deteriorate, it will form a cavity, that is, tooth decay. Therefore, tooth decay develops from small tooth decay, not real moths or other insects, but the result of teeth being gradually corroded. In severe cases, tooth decay will lead to tooth necrosis and tooth loss. For the cavities that have formed, you must go to the dentist immediately, so that the dentist can take timely measures to fill the cavities and prevent them from getting worse. Never have the idea of waiting, forget it. The view that "toothache is not a disease" is not only wrong, but also will delay the treatment, leading to the deterioration of tooth decay, tooth necrosis and possibly more tooth decay. If the pain is unbearable, sometimes even the dentist can't help you. It's really a small hole that doesn't mend, and a big hole suffers. At the same time, experts pointed out that after suffering from tooth decay, it is even more necessary to use high-quality fluoride toothpaste. The so-called "it's not too late to mend." Because high-quality fluoride toothpaste, such as Crest's Flutai formula ... >; & gt
Question 3: How to prevent "dental caries"? Dental caries, commonly known as tooth decay or cavity, is one of the most common oral diseases. So, how does dental caries happen and how to prevent it?
In daily life, most people think that dental caries are caused by eating too much sugar. In fact, this is only part of the reason, and the cause of dental caries is very complicated. After long-term research, the medical profession believes that dental caries is roughly the result of the interaction of four pathogenic factors. They are bacteria, food, teeth and time.
Specifically, there are a large number of bacteria living in the oral cavity, some of which, such as Streptococcus mutans, Actinomyces, Lactobacillus, etc., have the ability to produce chemicals harmful to teeth. The teeth are hard and the consumption of chewing food is small, but these chemicals can be gradually decomposed and destroyed in a short time. Therefore, cariogenic bacteria are essential for the formation of dental caries. Bacteria form a thin film on the surface of teeth, which is called dental plaque in medicine. Bacteria attack teeth based on dental plaque.
Bacteria need raw materials to produce chemicals harmful to teeth, and these raw materials are provided by sugars in food. Food is like a double-edged sword for teeth. On the one hand, food supplies nutrition to the body, making teeth stronger and enhancing the caries prevention ability of teeth; On the other hand, some saccharides contained in food remain in the mouth after chewing and swallowing, and are used by cariogenic bacteria to produce substances corrosive to teeth, thus destroying the hard tissue of teeth and leading to dental caries.
Teeth are very hard, but due to genetic and nutritional factors, the degree of calcification during tooth development is different. People with low calcification have uneven tooth surface and relatively weak enamel layer, which is easy to be destroyed. In addition, the irregular arrangement of teeth and the easy residue of food are also the causes of dental caries.
The last factor is time. It takes a certain time for cariogenic bacteria to synthesize destructive substances from nutrients in food residues. These four factors work together to cause dental caries. Therefore, the prevention of dental caries should also start from these four aspects. After dental caries occur, it is not static. Once bacteria break through the surface of teeth, they will quickly spread to the deep layer of teeth, further destroying the hard tissue of teeth, and then leading to pulpitis and even periapical periodontitis.
It is very important to prevent dental caries because the hard tissue of teeth can not regenerate after being destroyed. At present, the most effective way is to brush your teeth. Maybe you will say that you brush your teeth every day, but dental caries will still happen. In fact, brushing your teeth every day does not mean mastering the correct method of brushing your teeth. According to medical research, we should insist on brushing our teeth after meals every day and adopt the correct method when brushing our teeth. If the method is not correct, it will not only destroy bacteria and food residues, but also damage our teeth. Besides, you should often go to the hospital for examination, usually at least once every six months to once a year. Self-examination can only find superficial lesions, but it is difficult to find interdental caries. It can only be found with the help of a doctor's examination instrument. If dental caries have occurred, you should go to the hospital immediately, and the doctor will give corresponding treatment according to the degree of dental caries.
Question 4: How to prevent tooth decay and cultivate good eating habits? Every time you eat and drink water, the minerals on the surface of your teeth will be lost, causing the chance of tooth decay. The more times you eat and drink, the greater the chance of tooth decay. Therefore, the breakfast, lunch and dinner should be timed and have enough weight, avoiding eating outside the main meal to reduce the frequency of eating and drinking, and drinking water only when thirsty, which can reduce the chance of tooth decay. If you are really hungry between meals, you can have tea once.
Brush your teeth with fluoride toothpaste in the morning and evening Fluoride can strengthen your teeth and make them less susceptible to acid erosion. Fluoride can also help the lost minerals return to your teeth and restore the original tooth decay. Therefore, you should get up every morning and brush your teeth with fluoride toothpaste before going to bed at night.
Check your mouth regularly every year. Check your mouth at least once a year, find tooth decay as soon as possible, and receive treatment to prevent tooth decay as needed, such as applying dental caries preventive.

Question 5: How to prevent tooth decay? Hello, you can find some precautions about living habits through the Internet: jingyan.baidu/...f Of course, if you find yourself with tooth decay, I suggest you go to a regular institution to deal with it.
Question 6: How can we effectively prevent tooth decay? First, brush your teeth in the morning and evening, brush your teeth correctly, rinse your mouth after meals, and maintain oral hygiene.
Second, brush your teeth with fluoride toothpaste.
3. Seal the pit and fissure with pit and fissure sealant.
Fourth, eat more fruits and vegetables to improve the self-cleaning effect of oral cavity.
5. Go to the stomatological hospital for oral examination regularly to prevent problems before they happen.
Question 7: What are the methods to prevent tooth decay? Oral care experts in Shanghai Armed Police Corps Hospital put forward some direct and effective preventive measures against dental caries in children and adults:
First of all, choosing a good toothbrush is one of the important factors that can give full play to the function of brushing teeth. It is a wise choice to use a soft toothbrush with moderate hardness and density, rounded top and elastic handle, and change it frequently. Because the use of such a toothbrush can achieve the purpose of free movement in the mouth without hurting the gums;
Secondly, the correct brushing posture is also very important. If conditions permit, it is ideal to brush once after each meal, and the minimum requirement is once in the morning and evening;
Thirdly, it is very necessary to go to the dentist for oral examination regularly. Because the toothbrush may also be out of reach.
In addition to the above factors, there is also the most important preventive method, which is to choose toothpaste containing fluoxetine formula and high-quality silicon abrasive. For example, Crest's unique Flutai formula has excellent and efficient moth-proofing function, which is very effective in preventing root cavities.
