Question 1: What are the causes of dental caries? Dental caries (dental caries, commonly known as tooth decay) refers to a disease in which tooth tissue is gradually destroyed and disintegrated to form defects. Its incidence is high, especially in children, and it has become one of the most common diseases in all mankind. It has been listed by the World Health Organization as the third major disease prevention and treatment after coronary heart disease and cancer. Dental caries not only causes tooth collapse and defect, but also causes secondary diseases of pulp tissue and periapical tissue, even causes complications such as osteomyelitis caused by bone infection in Jiangxi, and even affects the whole body health. At present, it is considered to be a multifactorial disease, which is mainly caused by the interaction of bacteria, host and diet. ① Bacterial factors: Streptococcus mutans, Lactobacillus acidophilus, Staphylococcus aureus, etc. ② Food factors: the chemical action of food, refined carbohydrates produce acid through bacterial fermentation in the mouth, which often causes dental caries. Eat too much sugar, but lack calcium, phosphorus, vitamins A, D, B and so on. Can lead to the increase of dental caries criminal library. 3 host tooth and saliva factors: the pit and fissure of the tooth itself and the enamel are poorly developed; Low fluorine content is prone to dental caries; Crowded, dislocated and impacted teeth are also a condition of dental caries, which is easy to retain food and lead to the growth and reproduction of bacteria. Lack of saliva, dry mouth, etc. It often leads to serious dental caries. The cause of dental caries is 1. Your mouth is not clean. Babies can't rinse their mouths and brush their teeth. Although older children can gargle and brush their teeth, most children don't gargle and brush their teeth seriously. They can't insist on brushing their teeth in the morning and evening and after meals. Therefore, food residue remains between the teeth and the gap. Causes of dental caries II. I like to eat snacks, especially sugar. Some children even sleep with sugar in their mouths. We know that there are many bacteria in the mouth, especially lactobacillus, which can ferment sugar and food residues and produce a lot of lactic acid. This acid will destroy the tooth structure and lead to dental caries. On the other hand, children's nutritional status is poor, such as malnutrition, rickets and various chronic diseases, especially children with vitamin D deficiency rickets. Because of the lack of calcium in teeth, the tooth structure is loose, and it is more likely to be eroded by lactic acid to form dental caries. The cause of dental caries. The disease is best caused by molars, especially the first and second molars in the lower collar, followed by the first and second molars in the upper jaw, and then the bicuspids and upward incisors in the upper and lower jaw. Clinically, according to the depth of dental caries, it can be divided into shallow caries (enamel caries), moderate caries (shallow dentin caries) and deep caries (deep dentin caries). The caries site of shallow caries is only concentrated on the surface of teeth, and there is no chief complaint symptom when the disease occurs. There are white spots or brown, gray-black spots on the tooth surface. Rough surfaces can be detected with probes. Moderate dental caries: Clinically, deep cavities have been formed in teeth, and patients are sometimes sensitive to cold, heat, sweetness and acid. Progressive dental caries: when teeth are damaged, tooth decay is greater. The patient felt obvious cold, burning, sweet and sour pain. In addition, according to the development speed of dental caries, dental caries can be divided into three types: chronic caries, acute caries and static caries.

Question 2: How is dental caries formed? Dental caries, commonly known as insect tooth decay, is a chronic disease of hard tissue of teeth. Under the action of many factors, enamel and dentin are damaged and defective, and gradually develop into cavities. Dental caries is the most common dental disease among teenagers. According to the survey, the average prevalence rate of children in primary and secondary schools and kindergartens in China is about 50%. The cause of dental caries is the result of many internal and external factors. In recent years, with the development of medicine, the cause of dental caries has been further explained. It is considered that dental caries is a dental disease caused by the coexistence of bacteria, sugar food and dental caries resistance. The role of oral bacteria. Streptococcus mutans and Lactobacillus in the oral cavity multiply and ferment on the food residue left in the oral cavity to produce acid, which makes teeth corrode, soften and decalcify. After decalcification, dental cavities gradually formed. Sugar is a necessary condition for dental caries. Sugar plays a decisive role in the occurrence of dental caries. In particular, foods containing sucrose will increase dental plaque and streptococcus cariogenes will increase greatly. The body's resistance has obvious influence on the occurrence of dental caries. The resistance of the body includes the ability of teeth and the whole body to resist caries, and the internal factors of the body can affect the occurrence of dental caries. Especially when protein, minerals and vitamins are deficient, it will promote the occurrence of dental caries. Tooth shape, structure, location, oral hygiene, quantity and nature of saliva, nutrition, endocrine, genetic factors, systemic diseases, immune status, etc. , all have an impact on the occurrence and development of dental caries. Dental caries easily occur in the pit and fissure on the occlusal surface of teeth, the adjacent surface between two teeth of dislocated teeth, uneven dentition and overlapping teeth. The occurrence of dental caries is related to systemic diseases such as sticky saliva, poor oral hygiene, endocrine disorders, malnutrition, tuberculosis and the lack of trace elements. After the occurrence of dental caries, there was no inappropriate feeling at first, but there was a small hole in the tooth. When dental caries gradually develop and deepen, close to the sensory nerve endings of dental pulp, eating cold, hot, sour and sweet food will hurt. In severe cases, it can cause pulpitis or periodontitis, causing severe pain. Generally speaking, it has the following hazards: 1. When dental caries destroy enamel and invade dentin, patients will feel toothache when they encounter cold, hot, sweet and sour. Clinical examination shows that the teeth have holes and are dark brown. If not treated at this stage, the cavity will gradually deepen, involving the pulp and causing pulpitis. At this time, spontaneous pain can occur, and it can also cause ipsilateral headache, making patients fidgety. If left untreated, inflammation will continue to develop in the direction of root, causing periapical periodontitis, root swelling and pain, tooth loosening, biting pain and periodontal pus. In severe cases, there will be facial edema, fever and limited mouth. Bacteria may even enter the blood and cause bacteremia, which may be life-threatening. 2. If not treated in time, deciduous tooth caries can gradually develop into severe periapical periodontitis, leading to tooth dysplasia. If deciduous teeth fall off prematurely due to dental caries, it will not only affect the eruption of permanent teeth as scheduled, but also lead to the disorder of permanent teeth arrangement, resulting in dentofacial deformity. The early loss of permanent teeth due to caries and a large number of missing teeth will affect the chewing of food, which will inevitably increase the gastrointestinal burden and cause gastrointestinal diseases. 1. Severe dental caries leads to soft tissue around residual crowns and roots, causing ulcer erosion and even canceration. It may also become the focus and base camp of bacteria. 2. Bacterial toxins can reach all parts of the body through blood flow. Some data show that dental caries can cause iridocyclitis, rheumatoid arthritis, nephritis, rheumatic heart disease or viral myocarditis, systemic pain and so on. So, what should we pay attention to in preventing dental caries? First of all, pay attention to oral hygiene, learn to brush your teeth correctly, and develop the good habit of brushing your teeth in the morning and evening and gargling after meals. You can brush your teeth with a healthy toothbrush and fluoride toothpaste. Trace element fluorine can resist the corrosion of teeth by acid. Secondly, don't eat too much sugar, but also pay attention to nutritional supplements and physical exercise to enhance the ability to resist germs. Finally, remember to have regular oral examinations on weekdays, so as to find dental caries in time and carry out remedial treatment as soon as possible. The correct method is: the toothbrush should be brushed vertically along the long axis of the teeth, that is, from top to bottom when brushing the upper teeth and from bottom to top when brushing the lower teeth. When brushing the occlusal surface of the upper and lower teeth, the toothbrush bristles should be pressed against the teeth, brushed back and forth, and then brushed inside after brushing the outside.

Question 3: What are the causes of dental caries? The cause of dental caries is a multifactorial disease, which is mainly caused by the interaction of bacteria, host and diet. Details are as follows:

1, bacterial factor

Mainly Streptococcus mutans, as well as Lactobacillus acidophilus, Streptococcus acidogenes, Staphylococcus and so on.

2. Food factors

The chemical action of food, refined carbohydrates produce acid through bacterial fermentation in the mouth, often causing dental caries. Eat too much sugar, but lack calcium, phosphorus, vitamins A, D, B and so on. Can lead to the increase of dental caries criminal library.

3. Host tooth and saliva factors

Pit and fissure and enamel of the tooth itself are underdeveloped; Low fluorine content is prone to dental caries; Crowded, dislocated and impacted teeth are also a condition of dental caries, which is easy to retain food and lead to the growth and reproduction of bacteria. Lack of saliva, dry mouth, etc. It often leads to serious dental caries.

Question 4: How is dental caries formed? Dental caries is what we often say, tooth decay, and the main reason for its formation 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. The root cause of tooth decay is that the oral environment is acidic for a long time, which leads to excessive erosion of enamel. There are three main reasons for the acidic oral environment: 1, and bad oral cleaning habits. Can't insist on brushing your teeth in the morning and evening and gargling after meals, or brushing your teeth incorrectly; 2. Bad eating habits. Like to eat sweets or * * * food, which is not good for oral environment; 3. The natural oral environment is too acidic.

I suggest you try Xinglinji Sheng Hui Worm Tooth Prescription, which is a pure Chinese herbal medicine, which can change the structure of enamel surface and enhance the caries prevention ability of teeth.

Question 5: the formation of dental caries, how is dental caries formed? Hello, the root cause of dental caries is that the oral environment is acidic for a long time, which leads to excessive erosion of enamel. There are three main reasons for the acidic oral environment: 1, and bad oral cleaning habits. Can't insist on brushing your teeth in the morning and evening and gargling after meals, or brushing your teeth incorrectly; 2. Bad eating habits. Like to eat sweets or * * * food, which is not good for oral environment; 3. The natural oral environment is too acidic. I recommend you to try the pure Chinese herbal medicine tooth powder-Sheng Hui worm tooth formula. Sheng Hui worm tooth formula contains indigo, Radix Rehmanniae, etc. It is used for purging heat, moistening dryness, nourishing yin and tonifying kidney, and consolidating kidney qi, so as to fundamentally prevent decay and strengthen teeth.

Question 6: What are the common causes of tooth decay? There are many reasons. Just remember the four causes of tooth decay: host microbial food and time. 1: The host mainly refers to teeth. Some people are born with hypoplasia of teeth and hypoplasia of enamel, so it is difficult to resist caries factors. To put it bluntly, teeth are inherently poor. 2. Microbes, this refers to the maintenance of your oral hygiene, because there are many bacteria in people's mouths, which are usually in a state of balance. If you don't pay attention to oral hygiene, dental plaque will form, which you can understand as the base camp of bacteria. A lot of bacteria will accumulate here, and then there will be tooth decay. 3. Food Everyone knows that eating sugar can easily lead to tooth decay. This is because scientific research shows that sucrose is the sugar with the strongest cariogenic ability, so it is best to eat less sugar at ordinary times, or eat xylitol, sorbose and other sugar substitutes. These are all diseases that have no ability to cause caries. This requires a process, and this is the time. If you find tooth discoloration, go to the hospital to see if you can stop the progress of dental caries before it occurs, so that dental caries will not occur. That's about it. I hope I can help you.
