What are the causes of dental caries?

Children in childhood like to eat candy, no attention to oral hygiene, slowly formed on the caries. Dental caries will directly affect our diet, but also affect the beauty of our teeth. Here, we through this article to understand what the reasons for the formation of dental caries.
Causes of dental caries:

In daily life, most people think that suffering from dental caries is due to too much sugar, in fact, this is only part of the reason, the cause of dental caries is very complex. The medical profession after long-term study that: dental caries is roughly by the four pathogenic factors together results. They are bacteria, food, teeth and time.
Specifically, there is a large number of bacteria in the mouth to survive, some of which bacteria such as Streptococcus mutans, actinomycetes, lactobacilli have the ability to produce harmful dental chemicals, the teeth are very hard, chewing food wear on it Consumption is very small, but these chemicals can be a short time to gradually break down the destruction. Therefore, cariogenic bacteria on the formation of dental caries is essential. Bacteria in the tooth surface to form a thin film, medically known as plaque, bacteria is to plaque as a base to attack the teeth.
Bacteria produce harmful chemicals that require raw materials, and these raw materials are supplied by the sugar substances in the food. Food on the teeth like a double-edged sword, on the one hand, the food supply to the body to nutrition, so that the teeth more solid, and enhance the caries resistance of the teeth; the other hand, the food contains carbohydrate chewing swallow, part of the remaining Oral, the use of cariogenic bacteria, resulting in corrosive substances on the teeth, thereby breaking the hard tissue of the teeth, which led to the occurrence of dental caries.
Teeth are very hard, but due to genetic, nutritional and other factors led to the development of different levels of calcification in the teeth, the degree of tooth calcification is low, the tooth surface uneven, enamel layer is relatively weak, easy to be destroyed; Irregular, easy residue of food residues, but also susceptible to dental caries.
The last factor is time, cariogenic bacteria use of food residues in the synthesis of destructive substances need a certain amount of time, all of these four factors together to cause the occurrence of dental caries. Therefore, the prevention of dental caries from these four aspects to start. After the occurrence of dental caries is not static, once the bacteria in the tooth surface to open a breakthrough, it will quickly spread to the teeth deep, further damage the hard tissue of the teeth, leading to pulpitis and even apical perioditis and other diseases.
Through this article we understand the reasons for the formation of dental caries, which we prevent and protect the teeth have an important reference. The occurrence of dental caries directly affect our health, so to attract our attention, do the relevant protective work.
