1. Don’t keep licking the wound with your tongue A good blood clot is an important condition for normal healing of the extraction wound and avoiding infection. When spitting out the gauze ball, the alveolar sockets have stopped bleeding, and the blood clot has been formed at this time. However, if washed by saliva or drinking water, the blood clot will break down again, just like ice melting, eventually leading to clot dislodgement and rebleeding. Therefore, do not rinse your mouth and brush your teeth within 24 hours after tooth extraction, do not rinse your mouth hard when drinking water, and do not lick the wound with your tongue often. 2. Remember to bite the gauze ball when bleeding again after surgery Sometimes the bleeding has been stopped after spitting out the gauze ball, but after sports, talking, drinking, etc., the alveolar fossa bleeds again. If you can’t stop the bleeding, go to the hospital in time. 3. Pain and swelling after surgery, use painkillers + cold compresses Pain and swelling of the cheek after surgery are normal physiological reactions and inevitable. Generally, the more complex the tooth is, the more traumatic the extraction is, the more serious the post-operative reaction is. 4. Don’t crave and stay away from spicy and hot food Two hours after tooth extraction, you can eat liquid food, the first three days are mainly liquid food, the purpose is to facilitate swallowing, so as not to destroy the blood clot in the alveolar socket. Do not eat excessively hot and spicy stimulating food, but eat cool food, and take ice cubes or cold drinks by mouth to help stop bleeding. Try to rest on the same day and the next day, avoid strenuous exercise, and avoid lying down if you have a tendency to bleed, you can lie in a semi-recumbent position to reduce the blood flow in the head and face. Pay attention to supplemental nutrition, eat more food rich in protein and vitamins, and try not to smoke or drink alcohol for a week. 5. It is important and necessary to brush and rinse the mouth. After tooth extraction, it is more important to strengthen oral hygiene to avoid infection. Some patients hesitate to brush their teeth and rinse their mouths, resulting in poor oral hygiene and causing wound infection. As mentioned before, you can brush and rinse your teeth after 24 hours, just pay attention to gentle movements. After each meal, you can use mouthwash or light salt water to rinse your mouth, especially pay attention to the timely cleaning of food residues that fall into the jaw socket. 6. If there is no obvious discomfort after tooth extraction, no follow-up can be made. If there are sutures, the sutures can be removed at 5-7 days after surgery or at a nearby hospital. If the postoperative reaction is obvious, there is an increase in temperature, difficulty in opening the mouth and pain cannot be relieved, etc., you should follow up promptly. If severe pain in the extraction sockets starts to appear 3 days after surgery and cannot be relieved by taking painkillers, the pain radiates to the half side of the head, and there is a rotten odor inside the mouth, dry socket may have occurred, and timely follow-up should be made. 7. Post-operative reaction, everyone is different Post-operative reaction is temporary and usually does not cause serious discomfort. Everyone’s situation is different and not comparable, so don’t compare your feelings with other people’s experience. Treat post-operative reactions scientifically and calmly, and do not let them affect your normal life.
