The cost of wisdom tooth extraction is related to the direction of growth, the presence of obstruction and the ease of extraction process. For wisdom teeth that are better to be extracted, there is no obstruction and they are fully erupted, they can be removed directly with jaws and extraction forceps, and the price is relatively cheap, 200-300 RMB. However, for wisdom teeth that have ambiguous obstruction, gingival incision and removal of the alveolar bone are required before the tooth can be extracted, and the gums need to be sutured after the extraction. This would be a minor outpatient procedure and more expensive, at around$1000. Before wisdom tooth extraction, the cost of extraction can be judged by taking a curved tomogram and clinical examination in the oral cavity. The curved tomogram can effectively observe whether the wisdom tooth is obstructed and whether the gum is cut and the alveolar bone is removed for extraction.
