Does the middle superior alveolar nerve block affect the maxillary premolars and canine?

The middle superior alveolar nerve block is designed to anesthetize the maxillary premolars, as well as the maxillary first molar and the buccal tissue associated with these teeth. However, it does not typically provide anesthesia for the maxillary canine.

Hence, stating that the block affects the maxillary premolars and canine is inaccurate. The correct answer is that the middle superior alveolar nerve block does not provide anesthesia to the maxillary canine, thus affirming that the statement is false. Understanding the scope of the middle superior alveolar nerve block is integral for successful dental procedures and managing patient pain effectively.
