After the extraction, the anesthetic will wear off after about 3 hours. Due to the different teeth extracted and the different trauma, the patient’s pain sensation will be different. If the pain is unbearable after the anesthetic has passed, it is recommended to take painkillers, such as ibuprofen or fenpropathrin, in appropriate amounts, but painkillers should not be taken within 8 hours, and taking too many painkillers may cause liver damage, so it is recommended that patients take painkillers at their discretion under the guidance of physicians. After tooth extraction, patients are advised to take anti-inflammatory drugs, such as amoxicillin and metronidazole, for 3 days to prevent infection in the extraction socket. Patients are advised not to brush their teeth or rinse their mouth for 24 hours after tooth extraction to protect the blood clot in the extraction socket and not to let the rinse affect the healing of the extraction socket, etc.
