Baby tooth decay should be based on the severity of tooth decay, the degree of cooperation of the baby, etc., comprehensive consideration of the choice of treatment, may be carried out fillings, root canal treatment, extraction of milk teeth, etc., in order to improve the tooth decay, as follows: 1. Fillings: if the tooth decay is relatively shallow, did not affect the pulp, do a good job to pacify the work of the tooth, as early as possible, fillings can be carried out. 2. Root canals: if the decay of the tooth is relatively deep, affecting the pulp tissues and produce pain If the decay is deeper and affects the pulp tissue, causing pain, inflammation of the pulp, or inflammation of the root tip, root canal treatment is needed. Babies are relatively small, and root canal treatment requires good cooperation. Whether it is a filling or root canal treatment, you need to do a good job of calming the child. It can be done under local anesthesia or general anesthesia, and for children who are particularly uncooperative, it can be done under general anesthesia.3. Extraction of milk teeth: If the decay is particularly serious and cannot be retained, the milk teeth will need to be extracted. For younger children, permanent teeth will not erupt until half a year or more in the future, and gap retainers can be considered to maintain the integrity of the teeth. Oral hygiene is especially important for babies, parents are advised to help their children brush their teeth properly to prevent tooth decay, and fillings should be carried out as soon as possible when tooth decay occurs.
