During tooth replacement, you can eat coarse grains, such as bush rice or sorghum rice porridge, both of which can play a good role in stimulating jaw development. Because the children nowadays have a more refined diet, eating fruits are cut into small pieces, which is not conducive to the jaw building of the mouth. Whether eating fruit or eating vegetables, try to let the affected children bite themselves to exercise their biting ability, and fruits and vegetables have a certain cleaning effect on the surface of the teeth. If you are eating meat, you can let the child try to bite, which can massage the gums and stimulate the development of alveolar bone, which is beneficial to the later tooth replacement. During the tooth replacement period, eat less starchy food, such as cookies and popcorn, which contain high sugar and can easily lead to tooth decay.
