In general, the pain caused by anesthesia is relatively mild during tooth extraction. The pain that occurs during anesthesia is only a local surface pain, and no pain will occur after anesthesia. If the anesthesia is good, no very obvious symptoms will appear during tooth extraction, so in most cases, if some irritation or pain occurs when anesthesia is administered, it is mainly due to poor absorption and metabolism of anesthesia or incorrect position of anesthesia. Therefore, if local infiltration anesthesia is taken in the case of being closer to the nerve, severe pain may occur, so this situation can be nerve block anesthesia, and various methods can be taken to avoid having severe pain in the process of tooth extraction, and local pain relief treatment after tooth extraction can effectively relieve the tooth pain caused by the trauma of tooth extraction.
