What causes dental caries?
summary
In our real life, many people may have the experience of dental caries when they were young. Because most children are very fond of sugar, and sugar is the substrate of bacterial proliferation, and caries is a kind of chronic progressive damage disease under the influence of a variety of factors dominated by bacteria. What is the cause of dental caries? Next, I'd like to share my views with you.
What causes dental caries?
First: bacteria. The main bacteria causing dental caries in the oral cavity is Streptococcus mutans, which is easy to attach to the tooth surface and survive by using the ability of sucrose production and its own unique acid resistance, thus forming dental plaque, causing the destruction of tooth tissue, leading to the occurrence of dental caries.
Second, the host. Although the growth of bacteria and carbohydrate and other substrates lay a solid foundation for the occurrence of dental caries, if the host itself is not sensitive, it may not cause dental caries, so the occurrence of dental caries may be random, and also affected by the host's tooth hardness and saliva.
Third: oral cavity is the external environment of teeth, which is closely related to the occurrence of tooth decay, and its leading role is mainly food and saliva. Carbohydrate is related to the formation of plaque matrix and is the main energy source of bacteria in plaque. Changes in the quantity and quality of saliva can increase the incidence of dental caries.
matters needing attention
1. Reduce or eliminate pathogenic irritants: reduce or eliminate plaque, change oral environment, create clean conditions is an important part of caries prevention, the most practical and effective way is to brush teeth and gargle. 2. Reduce or control sugar in diet: China is a country with cereal as staple food, so it is difficult to control carbohydrate in diet to prevent dental caries. 3. Enhance the caries resistance of teeth: it is mainly to increase the fluoride in teeth by fluorination, especially to change the surface or surface structure of enamel to enhance its caries resistance.
