Why children and adolescents are prone to tooth decay

Children and adolescents are particularly prone to tooth decay, and some children have not changed their teeth, and their baby teeth have been seriously decayed, so why are children and adolescents prone to tooth decay?

Why children are prone to tooth decay

First of all, because many children and adolescents still have baby teeth, and baby teeth are less calcified than permanent teeth, the surface is not as hard as permanent teeth, and the resistance to bacterial corrosion is also poor.

Secondly, because children often like to eat sweets, there are more carbohydrates for bacteria to use, and children are not easy to develop the habit of brushing their teeth regularly, if the oral cleaning work is not timely or incorrect, food residues are more likely to remain in the mouth, especially sticking to the tooth surface and plugging between the teeth, which provides conditions for bacteria to produce acid and destroy teeth.

According to the investigators' statistics, primary molars and permanent molars have the highest chance of dental caries, followed by bicuspids. Because these teeth have more grooves, they are more likely to store food debris and bacteria, and they are not easy to rinse when rinsing. As a result of their long-term retention, the local acidity increases, and the dentin calcium acutes begins in the groove fossa.

In addition, some people have poor calcification of their teeth and abnormal morphological development; Some children's baby teeth fall out too early or too late, and the position of the permanent teeth that replace them is out of order.The third molars in the mouth are often tilted due to insufficient eruption position, and the gap between them and the second molars is increased, and the chance of tooth decay is also more.

For teeth, the chances of tooth decay in different parts of the tooth are not the same. The adjacent surfaces of two teeth are susceptible to tooth decay. This is due to the fact that the gap between the two teeth adjacent to each other is not easy to clean, and there is a lot of food residue accumulation, and the local acidity is high.
