Eat chewy food when changing teeth: When the child is about six or seven years old, permanent tooth buds begin to sprout one after another, replacing the original deciduous teeth. Although some children's permanent teeth have erupted, primary teeth often refuse to "give way", forcing permanent teeth not to grow out of the inner side of primary teeth, forming "double-layer teeth", resulting in irregular arrangement of permanent teeth. There are many reasons for the delay in extraction of deciduous teeth. The most common thing is that children eat too carefully and do not give full play to the physiological stimulation of teeth. The main function of teeth is to chew food, which can promote the growth, natural absorption and shedding of milk roots.

Therefore, with the growth of children's age, children should be allowed to eat more chewy food, such as jellyfish, peanuts, sugar cane and so on. So as to maintain a good stimulating effect on deciduous teeth and promote deciduous teeth to fall off on time. When the child's front teeth and back molars have erupted, you can add some celery, corn, apples and other foods to make the tooth change complete smoothly and let the child have a healthy and tidy tooth.
