What are the causes of dental caries?

Now a lot of people have the phenomenon of dental caries, dental caries is a very common disease, the disease to patients with a great deal of pain. A serious impact on the lives of patients, we all know that there are many reasons in life can cause dental caries, but the specific reasons? Xiaobian for the following detailed description of what, the cause of dental caries what.
Caries is a multi-factor disease, mainly including three aspects: bacteria, diet, teeth and saliva, the three are interrelated, the lack of one can not occur caries. Current scholars believe that saliva as the external environment of the teeth, is an important factor affecting dental caries.

1. bacteria
Caries occurrence and development process, because the bacteria in the incidence of dental caries play a leading role, therefore, in recent years internationally recognized caries is a bacterial disease caused by caries a lot of bacteria, the most important is some Streptococcus mutans and Lactobacillus The These bacteria are mixed with mucin and food debris in saliva and are firmly adhered to the tooth surface and the fissure. This adhesive is called dental plaque or dental plaque. Plaque in a large number of bacteria produce acid, resulting in plaque below the enamel surface decalcification, dissolved. Clinical studies have shown that dental plaque and more dental caries are also more.
2. diet
In the process of dental caries, diet is an important indicator of bacteria. Food contains a lot of carbohydrates and sugar, these substances not only supply plaque bacteria life and activity of energy, but also through the role of bacterial metabolism to produce glycolic acid, acid long-term retention in the tooth surface and fissure, the enamel off Mine damage, followed by some of the bacteria and the protein dissolved to form cavities. Caries a lot of carbohydrates, the most important is sucrose.
Dental development period, nutrition determines the biochemical structure of dental tissue, good calcification of the teeth with high caries resistance. If the food contains mineral salts, the main vitamins and trace elements such as calcium, phosphorus, vitamin B1, D and fluoride and other deficiencies, dental caries resistance is low, causing the incidence of dental caries. Deciduous teeth in the fetus that has occurred, development and calcification, the mother of the new breast nutrition, although the development of fetal deciduous teeth, although there is no decisive impact, but the strengthening of maternal nutrition is still beneficial to the calcification of deciduous teeth. Unless the mother suffering from severe metabolic or genetic disease, the general deciduous teeth is not easily affected.
3. teeth
The shape, structure and location of the teeth are significantly related to the incidence of dental caries. Dental teeth and fissure is the development of the process of leaving defects, deep fissure is easy to stay cells and food debris, and difficult to remove, easy to induce dental caries. Mineralization, especially calcified teeth, enamel and dentin density is not high, low caries resistance, susceptible to dental caries. Fluoride in the mineral mineralization structure is very small, but it is important to enhance the caries resistance of the teeth. Teeth containing the amount of fluoride is not easy to occur dental caries. Deciduous teeth and young permanent teeth of the structure and degree of calcification are not mature enough, so susceptible to caries factors, the prevalence of caries rate.
Saliva is the outer environment of the teeth, plays a buffer, washing, anti-rust or antibacterial effect. Large and thin saliva can wash the surface of the teeth, reducing the accumulation of bacteria and food debris. The amount of small and thick saliva easy to stay, to help plaque formation and adhesion on the tooth surface. The nature and composition of saliva affect its buffering capacity and also affect the living conditions of bacteria.
This article for everyone to introduce some of the causes of dental caries, dental caries caused by a variety of reasons, mostly with everyone's diet, Xiao Bian here prompted readers friends, dental caries is very big, so the parents for the future of the child To do a good job for the prevention of dental work.
