Children’s dental caries can be solved by filling treatment, root canal treatment as well as extraction. 1. Filling treatment: If the tooth has actually been damaged, but the pulp and nerve have not been harmed, it can be filled after removing the bacteria and necrotic tissue on the surface. If caries occurs in the baby teeth and the loss of tooth tissue is large, the shape of the crown can also be restored with a pre-formed crown. 2. Root canal treatment: If caries has damaged the nerve of the tooth, it is necessary to kill the nerve treatment, that is, after root canal treatment, to fill the tooth. 3. Extraction: If the caries is so severe that it has damaged the entire tooth, and there is obvious wobbling of the tooth, it means that there is no longer a need to save the tooth, and the tooth can be extracted at this time. Children’s dental caries may also have other treatment methods, it is recommended to consult a doctor in a timely manner, improve the examination, under the guidance of the doctor’s scientific management.
