What area is anesthetized by palatal local infiltration?

Explanation:
Palatal infiltration numbs only the soft tissue right around where the injection is placed. The local anesthetic blocks nerve firing in the surrounding palatal mucosa and periosteum, giving numbness to that immediate soft-tissue area. The dense hard palate bone behind it isn’t reliably affected by this small, localized diffusion, so the bone itself remains sensate. To numb the hard palate bone, a nerve block such as the greater palatine or nasopalatine block would be needed. The buccal mucosa isn’t affected because the injection is on the palatal side, not the cheek side.
