What are the factors causing dental caries?

The incidence of dental caries is getting higher and higher, and the incidence of the disease is becoming more and more widespread, which brings a lot of trouble to the patient's life. What is the cause of dental caries? Below, everyone will come to understand the cause of caries. Warm prompt: if you are a patient, please consult the experts as soon as possible, accept treatment, and wish you a speedy recovery.
Dental caries is a multifactorial disease, mainly including three aspects: bacteria, diet, teeth and saliva, the three are related to each other, and lack of one aspect of dental caries can not occur. At present, scholars believe that saliva, as the external environment of teeth, is an important factor affecting dental caries.
1. bacteria
And the development of dental caries, because bacteria play a leading role in the etiology of dental caries and dental caries is recognized internationally in recent years many kinds of bacteria bacterial disease caused by caries, the most important is some mutans streptococci and lactobacilli. These bacteria are mixed with mucin and food debris in saliva and firmly adhere to the surface of the tooth and the pit. This adhesive is called plaque or plaque (dental, plaque). A large number of bacteria producing acid in plaque, resulting in decalcification and dissolution of the enamel surface below plaque. Clinical investigation showed that children with more plaque in the oral cavity also had more caries.
2. diet
Diet is an important part of bacteria during dental caries formation. Contains large amounts of carbohydrates and sugars in food, bacterial life and activity energy of these substances can supply the plaque, and the bacterial metabolism of the glycolysis to produce organic acid, acid lingering on the teeth surface and fissure, the enamel demineralization after damage, some bacteria and dissolved protein formation of cavity. There are many kinds of cariogenic sugar, and the most important one is sucrose.

3. teeth
The morphology, structure and location of teeth are closely related to caries. The defects in the development of the tooth bite surface are the retention of cells and food debris in the deep fossa, and it is difficult to remove and cause caries. Lack of mineralization, especially in the teeth with insufficient calcification, the density of the enamel and dentin is not high, the resistance to caries is low, and it is prone to caries. The content of fluoride in the teeth of the mineralized structure although very few, but it is very important to enhance the anti caries of teeth. Dental fluorosis is difficult to occur when there is adequate fluoride in the teeth. The structure and calcification degree of deciduous teeth and young permanent teeth are not mature enough, so they are susceptible to caries and have high caries rate.
The above content is today to introduce the etiology of dental caries, now we should know how the caries is it, if all of dental caries and other aspects of the problems and opinions, please consult your dentist experts, get more knowledge about dental caries.
