Does the greater palatine nerve block provide anesthesia for the maxillary posterior teeth?

The greater palatine nerve block is specifically designed to anesthetize the palatal tissues of the maxilla, primarily the hard palate, from the canine to the molar region. While this block is effective in numbing the soft tissues and some of the bone in the area, it does not achieve anesthesia of the maxillary posterior teeth themselves, such as the molars and premolars.

The maxillary posterior teeth receive their sensory innervation mainly from the posterior superior alveolar nerve, which is not affected by the greater palatine nerve block. Therefore, even if the soft tissue overlying the teeth is anesthetized, the teeth themselves remain sensitive unless an additional block targeting the posterior superior alveolar nerve or another relevant nerve is performed.

This rationale confirms that the greater palatine nerve block does not adequately provide anesthesia for the maxillary posterior teeth, supporting the conclusion that the answer is "no."
