To prevent dental caries, first pay attention to oral hygiene. Brush your teeth thoroughly in the morning and evening and use fluoride toothpaste. Rinse your mouth promptly after meals to avoid the retention of food residues.

Have regular oral examinations. If dental caries occur, get them filled in time to prevent further development.

In addition, the grooves of newly erupted permanent teeth in children are relatively deep, which can easily lead to dental caries. At this time, pit and fissure sealing can be done to prevent dental caries.

Also, pay attention to reducing the consumption of sweet foods such as pastries and candies, which can effectively prevent dental caries.
