To perform a procedure or extraction on tooth #30, which nerve should the dentist anesthetize?
Show answer and explanation
Correct answer: A. Inferior alveolar nerve
- A. Correct. Tooth #30 (mandibular first molar) is anesthetized by an inferior alveolar nerve block, which numbs the mandibular teeth on that side (often supplemented by long buccal for soft tissue).
- B. The lingual nerve supplies the tongue and lingual soft tissue, not the pulp of #30.
- C. The (long) buccal nerve supplies buccal soft tissue/gingiva of molars but not the tooth pulp itself.
- D. The mental nerve supplies the chin/lip and labial gingiva of anterior teeth, not molar pulp.
