If a child’s milk teeth fall out, the permanent teeth will erupt afterward; if the permanent teeth fall out, no new teeth will erupt. 1. If a child’s milk teeth fall out, the permanent teeth that replace the milk teeth will continue to erupt; and the milk teeth that fall out usually do not need special treatment, keep the wound clean so that the wound heals itself, and wait for the subsequent corresponding permanent teeth to erupt during the developmental period. 2. If a child’s permanent teeth fall out, it will not grow new teeth again. After the permanent teeth fall out, it is necessary to carry out the tooth repositioning and fixation treatment in time in order to save the permanent teeth as much as possible; if it is not possible to save them, it is necessary to carry out the restoration treatment for the missing teeth after the wound is healed. It is recommended that children who have lost their teeth should go to the doctor for regular treatment in time to avoid delaying their condition.
