After the extraction, no pain is felt for a short period of time because of the anesthetic. After about two hours, the drug will lose its effect and the wound will start to swell and hurt. In some cases, the anesthetic may last longer. This is nothing to worry about, but it helps to reduce the pain. The pain will be worse on the day of the extraction and will last for about three days. It will get lighter in the following days. If the pain is getting worse after the extraction, you must go to the hospital to see the doctor. Exclude the possibility of dry socket or infection. If you are afraid of pain or have unbearable pain at night, you can take oral painkillers such as Sanli pain and ibuprofen. Usually when you have a tooth extracted, the doctor will ask you to bite down on a piece of gauze, which can be spit out 30-40 minutes after the extraction is completed. The medication injected during the extraction will numb the local nerves, so some people may have difficulty in feeling, and of course the nerves that are numbed also include the nerves that control the tongue, so when spitting out the gauze, you just need to turn your mouth down and flick the gauze outward with your tongue. Do not brush or rinse your teeth for 24 hours after tooth extraction to protect the blood clot in the extraction socket from falling off (to lay a good foundation for future wound K-healing and to prevent infection in the extraction socket), and then you can resume rinsing and brushing your teeth, but also try not to touch the extraction site. After tooth extraction, there will be very much saliva, but this saliva should not be spit out, but must be swallowed. This is because spitting will make the wound bleed and slow down the wound K-healing. Try not to touch the extraction wound for 24 hours after tooth extraction, and it is normal to have a small amount of red blood in the mouth. If you can feel obvious bleeding or spit out a lot of blood clots, you should go out to the hospital to deal with it. Therefore, women should avoid the period of vacation. It is better not to extract teeth for a day or two before or after. If you have clotting disorders or are taking anticoagulants such as aspirin, you should tell the doctor before the extraction. After tooth extraction, you should talk less. Eat mainly liquid food, pay attention to the balance of nutrition, and do not eat food that requires hard chewing. Pay attention to oral hygiene and never eat hard things. Do not drink hot water, at most warm water, on the same day, because hot water will promote the return of blood to the wound circle, which is very unfavorable to the wound K-healing and the formation of bone tissue, and will aggravate the swelling. Cool water, on the other hand, decelerates the blood flow in the wound area and allows for better K-healing. You can drink appropriate amount of fruit juice and take vitamin C and B to enhance wound healing. It is strictly forbidden to drink strong alcohol, not to smoke and not to eat spicy food for one week after tooth extraction. Especially, smoking must be prohibited. Talk less after surgery, do not do excessive physical labor and strenuous activities for 2~3 days, and ensure sufficient rest and sleep. Avoid touching the wound with tongue or hand as much as possible, and do not tear off the clot on the wound to avoid bleeding again. Seven days after the removal of the stitches, even after the removal of the stitches, attention should be paid to the recovery after half a month, and then it is possible that after the removal of the stitches there will be stuffing at the extraction of teeth for dinner. Generally, one month after the extraction, the new bone will be filled with the tooth extraction wound. It takes about two to three months to fully recover (i.e., all bone tissue is formed).
