It is a normal phenomenon that after the anesthesia drug wears off, painful symptoms will appear at the site of tooth extraction. For patients with mild pain symptoms, no special treatment is needed for the time being. During the recovery period, it is recommended to consume liquid or semi-liquid food as much as possible to avoid aggravating the pain. For patients with more obvious pain, ice towels and ice cubes can be used to apply local ice packs to the location of tooth extraction. Ice packs can reduce the bleeding and exudation symptoms at the location of gum injury and also reduce the sensitivity of the nerve for the purpose of pain relief. Patients with severe pain symptoms, serious wound swelling, and patients for whom icing is ineffective, can take some anti-inflammatory and pain-relieving drugs as prescribed by the doctor. Clinically used anti-inflammatory pain medications include aspirin, acetaminophen, ibuprofen and other non-steroidal anti-inflammatory drugs. These drugs can achieve the purpose of anti-inflammation and pain relief by inhibiting the synthesis of prostaglandins and reducing the phagocytosis of granulocytes and monocytes. In addition, you can also seek medical treatment in time, the doctor will choose the right medication for the patient to relieve pain according to the situation. If the pain is due to residual roots left behind or dry socket occurs, debridement or extraction should be performed in the hospital to relieve the pain by removing the irritating factors. In addition, accidental fractures caused by improper extraction operations also need to be ruled out. Patients should pay attention to avoid rinsing and brushing their teeth on the day of tooth extraction, and they should also try to avoid drinking hot water to avoid stimulating the wound site, accelerating local blood circulation and increasing bleeding. Some patients may have feverish reactions after tooth extraction. If the symptoms are not relieved for a long time, it may be due to infection at the gum injury site, and it is recommended to go to the hospital for treatment immediately.
