What is a fixed tooth?

Static teeth refer to dental caries (commonly known as decayed teeth), which refers to a disease in which tooth tissue is gradually destroyed and disintegrated to form defects. The incidence rate is high, especially in children. Dental caries not only causes tooth collapse and defect, but also causes diseases of pulp tissue and periapical tissue, causing jaw inflammation or infection, affecting the whole body health and doing great harm to human beings.

Resting caries: the state in which caries stops at a certain stage and does not continue to develop due to the change of pathogenic factors during the progress of caries.

Dental caries is an important disease that harms children's health. It is a simple, feasible and effective method for children to learn to brush their teeth. Brushing teeth can reduce the occurrence of dental caries. Children who brush their teeth twice in the morning and evening have the lowest dental caries rate, only 45.5%, which is lower than the average dental caries rate 1/3. People who brush their teeth before going to bed have a lower caries rate than those who brush their teeth in the morning, and those who brush their teeth in the morning have a lower caries rate than those who don't brush their teeth. It can be seen that the habit of brushing teeth in the morning and evening is a good way to prevent dental caries.
