Tooth decay in the incisors of children, that is to say, caries in the incisors of children. At this time, we should mainly check the situation of the child’s age, if the child is before 6 years old, generally the decayed teeth we consider should be the milk teeth. If the child is around 6 years old and the baby tooth is decayed, we can consider to extract it directly and wait for the permanent tooth below to erupt after extraction. If the tooth replacement time is earlier, such as 3 or 4 years old children. In this case, we usually consider to repair the decayed incisors by decontamination and filling in dentistry. But if the child is after 6 years old, then most of the time it is the permanent teeth that have this problem. For permanent teeth, we definitely try to preserve them. If the decay is deeper and pulpitis is present, then we should try to apply apical induction molding to keep the tooth in the oral cavity and continue to serve the oral function.
