The cost of orthodontic treatment for adults can range from about$4,000-5,000 to about$20,000-30,000,000. The specific cost depends on the specific situation of the teeth in the mouth, if the degree of malformation is not serious, only 2-3 teeth are malformed, it is easier to correct, the cost required is not too much, about 4000 yuan to solve the problem. If the malformation is very serious, the whole mouth of the teeth need to be corrected, or even need to extract teeth, so the cost may be slightly higher. If there are also cavities or pulpitis and other diseases in the mouth, the disease should be treated first, and then orthodontic treatment will be carried out after treatment, so the cost will also be higher.
