Many patients come to the hospital and ask the pediatric dentist, “Does my child need treatment for tooth decay? Doesn’t it have to be replaced? Won’t it be fine after the teeth are replaced?” Here we need to understand: What is the role of healthy baby teeth for the growth of children? First of all, milk teeth play an important role in chewing, that is, eating. If the decay of the baby teeth is not treated perfectly, the replacement teeth will be unattractive or untidy, and the health of baby teeth is directly related to the health of permanent teeth. Therefore, parents, if your children have black teeth, toothache, blocked teeth and other discomfort, do not ignore, whether they can grow up to be beautiful and handsome depends on whether you take them to the dentist or not, parents who take their children for routine dental checkups are responsible parents.
