The vast majority of teeth do not require anti-inflammatory treatment after extraction because for teeth without inflammation, there is no obvious inflammation after extraction and there is no need to take anti-inflammatory medication. However, the following two cases must take anti-inflammatory drugs after tooth extraction, such as cephalosporin or ornidazole. First, acute and chronic inflammation existed in the tooth before extraction, and it is likely to cause the spread of inflammation in the process of tooth extraction, to take anti-inflammatory drugs early after extraction, which can effectively prevent the spread of inflammation. Secondly, if the tooth is damaged in the process of extraction, such as the presence of blockage or ambulation, gingival incision, alveolar bone removal, tooth splitting, etc., these steps may cause edema in the extraction wound, and oral anti-inflammatory drugs are needed to prevent infection after surgery.
