When the child is in the period of changing teeth, you can give the child more chewy food, such as jellyfish, peanuts, sugar cane and so on. Give the deciduous teeth a good stimulus to make them fall off on time. At the age of ten, due to the eruption of front incisors and back molars, corn, apples and other foods can be appropriately added, which is helpful for the smooth completion of tooth replacement.
