Anesthesia for tooth extraction in children generally has no effect on the body, and the local anesthetic drugs used clinically for tooth extraction are relatively safe. There are people who have allergic reactions to local anesthetics, but the chances are very low. If the tooth is extracted without anesthesia, there will be obvious pain, which will cause the child to resist the treatment and will also form a psychological shadow for future treatment, so the tooth should be extracted after anesthesia. After anesthesia is administered, tooth extraction is usually painless and will make the process of tooth extraction smoother. The anesthetic has no obvious effect on the child’s body and the anesthetic is safe, so when the child is having a tooth extracted, the anesthetic should be administered first and the tooth extraction should be done after sufficient local anesthesia to prevent pain when the tooth is extracted.
