How to prevent tooth decay in children's dental care

Specifically, there are a large number of bacteria living in the mouth, some of which such as Streptococcus mutans, Actinomycetes, Lactobacillus, etc., have the ability to produce chemicals that are harmful to the teeth, the teeth are very hard, and the wear and tear of chewing food consumes it very little, but these chemicals can gradually decompose and destroy it in a short period of time.Therefore, cariogenic bacteria are essential for the formation of dental caries. The bacteria form a thin film on the surface of the tooth, which is medically called plaque, and the bacteria attack the teeth based on plaque.

Bacteria produce chemicals that are harmful to your teeth, and these ingredients are supplied by sugars in food. On the one hand, food provides nutrients to the body, making the teeth stronger and enhancing their resistance to caries. On the other hand, some of the sugars contained in food are chewed and swallowed, and some of them remain in the oral cavity and are used by cariogenic bacteria to produce substances that are corrosive to teeth, thereby destroying the hard tissues of the teeth, and then leading to the occurrence of dental caries.

Teeth are very hard, but due to genetics, nutrition and other factors, the level of calcification in the process of tooth development is different, people with low degree of tooth calcification, the tooth surface is uneven, the enamel layer is relatively weak, and it is easy to be destroyed; In addition, the teeth are not aligned and food debris is easy to remain, which is also a cause of tooth decay.

The last factor is time, and it takes a certain amount of time for cariogenic bacteria to use nutrients from food residues to synthesize damaging substances, and all four factors work together to cause tooth decay.Therefore, the prevention of tooth decay should also start from these four aspects. Once the bacteria open a breakthrough in the tooth surface, it will quickly expand deeper into the tooth, further destroying the hard tissue of the tooth, and then leading to diseases such as pulpitis and even apical periodontitis.
