The cost of filling children’s tooth decay needs to be different from one person to another, and it is distinguished by the degree of tooth decay. Specifically as follows: 1.If the tooth itself only has a small black spot or is shallowly decayed, the cost is not very high, if it is shallowly decayed, it is about 200 RMB; 2.If the decay is more serious and does not invade the nerve, that is, the treatment of deep caries, the cost is about 300 RMB; 3.If the child has pain or swelling, root canal treatment is needed, that is, the treatment of pulp is needed, in this case, the cost is relatively high, one tooth needs 600-700 RMB. There will be differences during the period, such as some of the caries need to be treated under anesthesia, then there is anesthesia cost. Before doing each treatment, we also need to carry out examination items, including whole mouth examination and radiological examination, such as taking dental film, which will generate new costs, which are commonly occurring in the outpatient clinic; 4, some children need to go to the operating room to do general anesthesia treatment because they do not cooperate, and the anesthesia cost will be relatively high, about 900-1200 yuan per tooth, and there are also anesthesia costs in it, so if we do The cost of general anesthesia will be higher.
