Anonymous users2024-02-151 Bacteria Bacteria are the leading cause of tooth decay. Bacteria mainly adhere to the tooth surface with the help of plaque, and the food debris in the oral cavity is degraded and polymerized to produce highly viscous dextran to form a plaque matrix, and on the other hand, it produces acid to demineralize the tooth.
2 Oral environment The oral cavity is the external environment of the teeth, which is closely related to the occurrence of tooth decay, and its leading role is mainly food and saliva. Carbohydrates are involved in the formation of plaque matrix and are the main source of energy for bacteria in plaque. Changes in the quantity and quality of saliva can increase the rate of tooth decay.
3 Host The tooth is the host in the process of tooth decay. The morphology, structure and position of teeth are directly related to the development of tooth decay. Pits and fissures are defects left behind during development, and bacteria and food debris are easily retained in deep sockets, and they are not easy to clean, leading to an increased incidence of tooth decay.
If the tooth is not mineralized enough, especially if the calcification is insufficient, the density of enamel and dentin is not high, and the caries resistance is low, the probability of tooth decay is beaten.

It is a necessary condition for the occurrence of caries, and it is generally believed that there are two types of cariogenic bacteria, one is acid-producing bacteria, which are mainly Streptococcus mutans, Actinomycetes and Lactobacillus, which can decompose carbohydrates and produce acid, resulting in tooth inorganic demineralization; The other is gram-positive cocci, which can destroy organic matter and cause cavities in the teeth after a long-term effect. At present, the main cariogenic bacteria are recognized as Streptococcus mutans, and others include Actinomycetes, Lactobacillus, etc.
Bacteria adhere to the tooth surface mainly with the help of plaque. After the carbohydrates in the oral retained food are degraded, on the one hand, polymerization produces highly viscous dextran to form a plaque matrix, and on the other hand, acid production demineralizes the teeth, and the composition of plaque is relatively complex, in addition to a large number of bacteria, there are sugars, proteins, enzymes and other substances.
2. Oral environment
The oral cavity is the external environment of the teeth, which is closely related to the occurrence of caries, in which food and saliva play a leading role.
When the quantity and quality of saliva changes, it can affect the caries rate, and it can be seen clinically that the caries rate of patients with xerostomia or saliva secretion is significantly increased. Patients with maxillofacial radiation** may have multiple dental caries due to destruction of the salivary glands; On the other hand, when the amount of lactic acid in saliva increases, or the bicarbonate content decreases, it is also conducive to the occurrence of caries.
3. Host
Teeth are the target organs in the process of caries, and the morphology, mineralization degree and tissue structure of the teeth are directly related to the occurrence of caries. On the other hand, the structure of teeth is closely related to the body, especially in development, which not only affects the development and structure of teeth, but also has a great impact on the flow, velocity and composition of saliva, so it is also an important link in the occurrence of caries.
4. Time
The occurrence of caries has a long process, from the initial caries to the clinical formation of caries cavities generally takes years, so even if cariogenic bacteria, suitable environment and susceptible hosts exist at the same time, caries will not occur immediately, only the above three factors exist at the same time for a long time, caries can occur, so the time factor is of great significance in the occurrence of caries.

Anonymous users2024-02-13Summary. The main reasons for kissing are as follows: 1. The presence of cariogenic bacteria; 2. Food is retained on the surface of the teeth, and bacteria use the residual food to multiply, and then produce bacterial toxins, thereby destroying the surface of the teeth; 3. The hardness of tooth structure, especially the deciduous teeth, is worse than that of permanent teeth, and the salinity is lower, so it is more susceptible to caries and progresses faster.

Tooth decay is usually caused by inadequate oral care or frequent eating of sweets, and if you want to improve it, you can use the method of filling teeth.
If you don't have a good habit of brushing your teeth and rinsing your mouth in your daily life, it may lead to bacterial infection, and there are more sweets in the food you usually eat, and a certain amount of acidic substances will be produced after eating sweets, which can destroy the minerals and enamel on the surface of the teeth, so that the bacteria will enter the inside of the teeth and gradually appear to rot and cause tooth decay.

Anonymous users2024-02-125. Resistance includes the ability of teeth and the whole body to resist caries, and the internal factors of the body can affect the occurrence of tooth decay. In particular, when protein, minerals, and vitamins are deficient, it can contribute to the occurrence of tooth decay. Eat more raw dairy products and nutritious foods to fully supplement minerals such as calcium, magnesium and phosphorus.
At the same time, active vitamin D supplementation can also effectively prevent tooth decay.
6. Phytic acid is the main form of phosphoric acid compounds in plant foods. Phytic acid is found in many foods such as cereals, seeds, nuts and legumes. While these foods are often claimed to be good for you, they also have some negative effects on teeth and bone health.
It hinders the absorption of phosphate, as well as other minerals such as calcium, magnesium, iron, and zinc, weakening teeth and leading to tooth decay.
7. Saliva plays the role of mechanical washing, antibacterial, anti-acid and anti-dissolution under normal circumstances. When the quantity and quality of saliva change, it can affect the caries rate, and the caries rate of patients with xerostomia or saliva secretion can be seen clinically increased. Patients with maxillofacial radiation** may have multiple tooth decay due to destruction of the salivary glands; On the other hand, when the amount of lactic acid in saliva increases, the saliva is too concentrated, which will also lead to tooth decay.
Brush your teeth every morning and evening, and make sure to brush your teeth for three minutes each time, inside and out. It's best to choose a smaller brush head. If you brush your teeth correctly, it may be because the pits and fissures of your congenital teeth are deeper, which makes you prone to plaque. >>>More
Tooth decay is divided into different stages according to the degree of caries, mainly shallow caries, medium caries, deep caries and a series of serious tooth pain problems caused by caries in a timely manner. In short, caries should be done as soon as possible, the sooner the better, the less it costs, and the less it costs. >>>More
Essential tremor is caused by abnormal signaling in specific areas of the brain, including the cerebellum, thalamus, and brainstem. The exact cause of the disease is unknown, but about 30% to 50% of patients have a family history and are inherited in an autosomal dominant manner. However, some people who have no family history can also get the disease.
In daily life, most people think that tooth decay is due to eating too much sugar, but in fact, this is only part of the reason, and the ** tooth decay is very complicated. After long-term research, the medical community believes that tooth decay is roughly the result of the joint action of four types of amino gens. >>>More
Tooth decay does not mean that there are toothworms in the teeth, tooth decay refers to the erosion of the teeth by bacteria, and the bacteria multiply in the oral cavity to produce toxic substances that continue to erode the tooth surface, causing the teeth to be continuously damaged from the outside to the inside.
