Which nerve is typically anesthetized for maxillary tooth extractions?

For maxillary tooth extractions, the anterior superior alveolar nerve is typically anesthetized because it provides sensation to the maxillary incisors and canines. This nerve branches from the maxillary nerve (a division of the trigeminal nerve) and travels down the anterior surface of the maxilla, supplying the teeth in the anterior region of the mouth. Anesthetic administration targeting this nerve ensures effective pain control during dental procedures involving the anterior maxillary teeth, such as extractions.

In contrast, the inferior alveolar nerve primarily innervates the mandibular teeth and is not relevant for maxillary procedures. The mental nerve, a branch of the inferior alveolar nerve, supplies sensation to the lower lip and chin but does not innervate maxillary teeth. The buccal nerve also does not contribute to the sensation of the maxillary teeth; instead, it provides sensation to the buccal soft tissues of the lower jaw. Thus, the anterior superior alveolar nerve is the appropriate choice for anesthesia during maxillary tooth extractions, ensuring adequate pain management for the specific region involved.
