Both tooth extraction and anesthesia have side effects. The anesthesia of oral tooth extraction is local anesthesia, and there are two kinds of anesthesia methods, one is block anesthesia and the other is infiltration anesthesia. If it is infiltration anesthesia, it is injected into submucosa or periodontal ligament, and there are local capillaries, and few * * * enter the blood circulation. However, the injection of block anesthesia is deep, but it needs to be pumped back to see if it will return to the blood and then return to the medicine to prevent the anesthetic from entering the blood vessels. So little anesthesia enters the blood, and they can be metabolized quickly.
Therefore, anesthesia during tooth extraction will not harm the brain as long as it is in a reasonable dose. However, some people may have vomiting and gastrointestinal discomfort after playing anesthetic. This is normal. Don't worry. The effect of general anesthetics will fade after a few hours, and patients will not have other obvious discomfort. But if you find that your mouth is numb for a long time, you'd better go to the dentist.
In addition, just after tooth extraction, patients will feel obvious pain in the wound after anesthesia, so they need to take some painkillers at this time. One day after tooth extraction, you need to use special mouthwash to reduce inflammation and speed up wound recovery. Diet should be light and easy to digest, and don't chew food too much, which will affect wound healing. If you still feel the pain of the wound one week after tooth extraction, you need to go to the hospital for local cleaning and sewing iodoform gauze to promote wound healing.
