It may be that pain as well as inflammatory symptoms are relatively mild and tolerable due to the patient’s small incision, and there is no need for treatment by pain medication for the time being, so it is not recommended to take painkillers. And all drugs can have side effects and have certain adverse effects on the human body, so it is recommended that drugs should not be applied as much as possible if they can be relieved by themselves. And the pain after tooth extraction is mostly caused by trauma or local inflammation caused by the process of tooth extraction, and pain can occur after the anesthetic medicine fails. These pains can be relieved by cold compresses, and anti-inflammatory drugs such as amoxicillin and cefadroxil can be used prophylactically, which can prevent secondary infection and help relieve pain to a certain extent. Therefore, generally if the pain is not severe, there is no need to use painkillers. When patients have severe pain or persistent unrelieved pain that affects rest and sleep, they can communicate with doctors and follow medical advice to apply pain medications such as ibuprofen and acetaminophen appropriately to relieve pain symptoms. If the pain appears again 2-3 days after tooth extraction or the pain intensifies, accompanied by bad breath and other symptoms, it is mostly considered secondary infection such as dry socket. At this time, it is recommended not to diagnose by oneself and blindly use pain medication to avoid misleading the doctor’s judgment of the disease, and it is recommended to immediately consult a doctor and use medication and treatment under the doctor’s guidance. In addition, patients should not rinse and brush their teeth on the day after tooth extraction, but can brush their teeth the next day. Try to avoid licking or sucking the wound with the tip of the tongue to prevent bleeding or infection caused by falling clots, and if abnormal conditions occur, such as more than bleeding, they should seek medical treatment promptly. Pay attention to diet recently, it is recommended to eat semi-liquid food or soft food with appropriate food temperature on the same day, and avoid chewing with the extraction side.
