The ways to prevent tooth decay in children include careful brushing, eating less sweets, sealing the fossa, and regular dental checkups, etc. The specific analysis is as follows:
1. Brush teeth carefully: tooth decay is caused by bacteria using food residues in the mouth together with saliva to produce harmful substances, destroying the calcium structure of the teeth to form cavities, brushing teeth carefully to reduce the breeding of bacteria, to a certain extent, can be predetermined for tooth decay.
2. Eat less sweets: Sweets are easy to cause bacterial growth, resulting in tooth decay.
3. Fossa sealing: Newly grown permanent molars can go to the hospital to do fossa sealing to prevent fossa caries.
4. Regular dental checkups: Regular dental checkups can treat small cavities that may have formed and prevent them from expanding.
It is recommended that children develop the habit of brushing their teeth in the morning and evening and pay attention to oral hygiene.
