Which nerve anesthetizes the soft palate?

Which nerve anesthetizes the soft palate?

• A. Lesser palatine nerve
• B. Greater palatine nerve
• C. Lingual nerve
• D. Infraorbital nerve

Answer: (A)

Sensory innervation of the soft palate comes from the lesser palatine nerves, branches of the maxillary division via the pterygopalatine ganglion. These nerves specifically supply the soft palate mucosa, the uvula, and the tonsillar region. In contrast, the greater palatine nerve supplies the hard palate and the palatal gingiva of the maxillary teeth, the lingual nerve serves the tongue and floor of the mouth, and the infraorbital nerve covers the cheek and upper lip area. To anesthetize the soft palate, you target the lesser palatine nerves, often near the lesser palatine foramen or within the soft palate itself.
