What causes the cause of dental caries

Dental caries, which is a common childhood dental disease, causing great harm to children's teeth. Therefore, parents should actively help children to prevent dental caries. Parents and friends in order to help children to prevent dental caries, we must know what causes the cause of dental caries? In general, the cause of caries caused by the following four main points:
The cause of dental caries 1: bacteria

This is a necessary condition for the occurrence of caries, it is generally believed that there are two types of cariogenic bacteria, one is the production of bacteria, mainly Streptococcus mutans, actinomycetes and Lactobacillus, carbohydrate decomposition can produce acid, Leading to tooth mineralization of inorganic matter; the other is the Gram-positive cocci, can damage the organic matter, after a long period of time can cause dental cavities. Currently recognized as the main cariogenic bacteria Streptococcus mutans, the other also includes actinomycetes, Lactobacillus and so on.
The cause of dental caries 2: oral environment
Oral cavity is the outer environment of the teeth, and the occurrence of caries is closely related to, which play a leading role in food and saliva.
The cause of dental caries 3: host
The tooth is the target organ in the process of caries. The shape, mineralization and organization of the tooth are directly related to the occurrence of caries. If the teeth of the teeth and the poorly mineralized teeth are more susceptible to caries, the degree of mineralization In addition, the structure of the teeth and the body are closely related, especially in the development, not only affect the development and structure of the teeth, but also on the saliva flow, Flow rate and its composition also has a great impact, and therefore is an important part of the occurrence of caries.
Cause of dental caries 4: time
The occurrence of caries has a long process, from the initial caries to the clinical formation of dental cavities generally 1.5 to 2 years, so even if the cariogenic bacteria, the appropriate environment and susceptible host coexistence, dental caries will not occur immediately, Only the above three factors exist for a long time, it may produce caries, so the time factor in the occurrence of dental caries is of great significance.
Through the above detailed description of the cause of dental caries caused by what, I believe that parents can provide some help. At the same time, let the children develop a good brushing habits, do not eat sweets before going to sleep, if you eat to gargle or brush your teeth, to avoid resident bacteria.
