It is very common for children to have new teeth erupt without losing their baby teeth, and when this is found, the corresponding baby teeth can be extracted. The common reason for such a situation is that children now have a relatively fine diet, and eat relatively little coarse and mixed grains, so there are often new teeth erupting, and the milk teeth are not yet able to fall out on their own. During the period of tooth replacement, children should be encouraged to eat more nutty foods to promote jaw bone development. When this happens during tooth replacement, try to make the baby teeth fall out on their own through the action of chewing. If the baby teeth are not able to fall out, loosen and affect the child’s feeding, etc., you can consider extracting the corresponding baby teeth. Such extraction of baby teeth is very simple, and sometimes it is only necessary to apply anesthetic, so parents do not have to worry too much. In addition, during the period of tooth replacement, it is recommended to take the child for oral examination regularly, once in about 3-6 months.
