Tooth extraction in children is done differently depending on the type of tooth. The details are as follows: 1. If the tooth to be extracted is a loose milk tooth, then local surface anesthesia is required, and then the loose milk tooth can be extracted with an extraction instrument. 2. If the milk teeth are not loose and the permanent teeth have already grown out, surface anesthesia and local infiltration anesthesia will be applied, and then the milk teeth will be pulled out of the alveolar fossa with the extraction instrument by repeated shaking of the milk teeth in the direction of lips and tongue, and then the milk teeth will be pulled out of the alveolar fossa. 3. In case of multiple teeth in the maxillary median region, they can be extracted with extraction instruments after local infiltration anesthesia. 4. If it is an inverted and blocked supernumerary tooth hidden in the alveolar bone, it needs to be hospitalized for surgical treatment. After general anesthesia, the flap will be cut and the bone will be removed to reveal the supernumerary tooth, which will be extracted and then sutured. Children should go to the hospital to the professional doctor for tooth extraction, so as to avoid the improper operation of the method, so that the situation will be aggravated.
