Tooth extraction is a surgical treatment in dentistry and is covered by medical insurance. However, tooth extraction is basically performed on an outpatient basis, and the cost of outpatient surgery is generally not reimbursed for most residents’ medical insurance and NPS. However, if the balance on the medical insurance card is sufficient, it is possible to transfer the balance for tooth extraction. In addition, if a tooth has a buried blockage and needs to be hospitalized and extracted under general anesthesia, it can be reimbursed through the medical insurance. The percentage of reimbursement is directly related to the level of the hospital, which is relatively high for secondary hospitals, probably around 70%, and for tertiary hospitals, around 50%.
