1. Cultivate children's good oral care habits, such as teaching children to brush their teeth correctly, supervising children to brush their teeth in the morning and evening, and helping them brush their teeth when necessary. Rinse your mouth in time after eating and brush your teeth if necessary.

2. Educate children not to use teeth as tools, such as using teeth to bite open nut shells and crab legs. Teach children not to use their teeth as tools from an early age.

3. Pay attention to children's eating habits, reduce or control the sugar in children's diet, educate children to develop the habit of eating less snacks, sweets and cakes, and don't eat sugar before going to bed. Increase various complementary foods on time, and eat more coarse grains, foods containing fiber, phosphorus and calcium, fruits and vegetables. And maintain adequate nutrition and a balanced diet.

4. Regular oral examination. After the child's first tooth grows out, we should always pay attention to the child's oral health problems. Parents should take their children to the dental clinic for examination in 3-6 months. Children with frequent dental caries should shorten the examination interval and let them not resist going to the dentist.
