Whether or not anesthesia is required for a tooth extraction is a judgment call based on the degree and type of looseness of the tooth. If the tooth to be extracted is a particularly loose baby tooth, the root of which has been resorbed, the operation can be carried out without injection of anesthesia when it can be operated quickly and easily, and even if anesthesia is used, it may be the choice of applying a surface anesthetic, which generally does not cause the patient any greater pain. Other than that patients with tooth extraction generally need anesthesia, such as permanent teeth or more loose but not seriously loose teeth, local anesthesia is needed for extraction to reduce pain and better cooperate with the doctor’s operation. There are two main types of anesthesia for tooth extraction, block anesthesia and infiltration anesthesia. Block anesthesia involves injecting anesthetic into the upper or lower jaw near the nerve trunk and its main branches. Infiltration anesthesia refers to the injection of local anesthetics into the tissues to act on the nerve endings, commonly used local anesthetics are ativan and lidocaine hydrochloride. The extraction can begin a few minutes after the anesthetic is injected, and there is usually no pain during the procedure. Slight bleeding and pain after the operation is normal. During the recovery period, you should avoid spicy and overheated food, no smoking and no alcohol, so as not to affect the healing speed of the wound, and you should not brush or gargle for 24 hours after the operation. If inflammation occurs, you need to go to the hospital in time.
