Caries is the most common disease of the teeth, which meets at any age. The main causes of the occurrence of caries are microorganisms that destroy the structure of the enamel and lead to the development of caries. Many important role is played and wrong oral hygiene.

Caries is the most common disease of the teeth who suffer from about 98% of the inhabitants of the globe. At the same time there is no statistics on age-related dental damage by caries. The disease can be like an adult and a child with the same probability. This disease is considered the most common and delivers many troubles. The name of this disease of the teeth is derived from the word «Caries», that translated from Latin means Costaland.
The role of microbes in the emergence of caries
Caries is a pathological process that arises from the moment of teething and is accompanied by a disruption of tooth tissue mineralization. The impaired mineralization occurs due to the activities of the microbes, which later leads to the formation of the cavity in it. The main elements of the enamel are crystals of hydroxyapatite, which are destroyed due to the occurrence of acidic medium in the mouth. The acidic medium in the oral cavity arises due to the separation of organic acid bacteria, then the destruction of enamels in the teeth and the bacteria penetrate into the underlying layers, starting to destroy the structure of the tooth.
In the development of caries of teeth, not only the microbes present in the oral cavity are guilty, but also other factors of the inner environment of the body. First of all, this is the state of immune and digestive systems of the body. That is why the caries are considered as a consequence of the general disease of the body, followed by the lesion of the tissue of the tooth and call «Carious disease».
A huge role in the reasons for the appearance of caries plays food. The development of carious disease contributes to the lack of proteins, mineral salts, fluorine, vitamins, various trace elements. At the same time, food is the nutrient medium for microorganisms, the life activity leads to the development of caries.
Currently, scientists believe that it is of great importance to the predisposition to the development of the disease, which is transmitted by heredity, the state of the dental system during the period of development and teething. Previously, the 6th teeth are dispersed from constant teeth, so their enamel does not have time to be saturated with fluorine and calcium from saliva, because of this, they suffer primarily and poorly cleaned.
Incorrect cavity hygiene - the cause of caries
A special place in the development of caries is given to the oral hygiene. As a result, the development of caries occurs enough and properly maintaining the cavity of the mouth, which is confirmed by one of the latest concepts. On enamel, in those places, from where a mild flare with chewing is not filmed, a place of concentration of various bacteria, which are called cariesogenic. The seal of the plaque contributes to the inclusion of mineral salts in its composition, which leads to the formation of a toothache. Bacteria located in the plaque produce milk acid, which leads to damage to the enamel. This gives the beginning of the development of caries. Dextran (polysaccharide produced by bacteria for dental plates) plays an important role in the structure of the target, which is formed by bacteria from sucrose.
Each person has the action of carieseogeneic bacteria that are in the dental flask, manifests itself in different ways. Someone resistance to caries is high, someone is poorly expressed. It was revealed that persons with reduced immunity, the development of caries occurs more actively, also most susceptible to caries people with a more viscous saliva, in which the ratio of the content of mineral salts.
