Tooth extraction can be done with anesthesia, and for extraction of apparently loose teeth, lidocaine can be applied, and local infiltration anesthesia can be performed at the buccolingual mucosa of the affected tooth, and the tooth can be extracted after 3-5 minutes of drug absorption. When extracting maxillary anterior teeth, local infiltration anesthesia can be applied in the labial-buccal vestibular sulcus, respectively, and there is also block anesthesia at the incisor papilla. For extraction of maxillary molars, maxillary nerve block anesthesia and palatal major nerve block anesthesia are applied, and the entry points are the buccal side of the proximal mesial root of the maxillary second molar and the small palatal recess, respectively. For extraction of mandibular teeth, mandibular nerve block anesthesia is generally applied, and the entry point is the midpoint of the pterygomandibular ligament, in line with the distal middle 2-3 cm of the parotid papilla. In order to reduce intraoperative bleeding, an appropriate amount of epinephrine can be added to the anesthetic.
