The anterior superior alveolar nerve provides pulpal innervation to which teeth?

• A. Central incisors, lateral incisors, and canines
• B. Premolars
• C. Molars
• D. Canines and premolars

Answer: (A)

The anterior superior alveolar nerve supplies pulpal innervation to the maxillary anterior teeth: the central incisors, lateral incisors, and canines. This nerve is a branch of the infraorbital nerve (from V2) that travels to the maxillary anterior teeth and their facial gingiva, delivering the sensory fibers to their dental pulp.

Premolars are typically innervated by the middle superior alveolar nerve (and sometimes by the anterior superior alveolar nerve if the middle branch is absent), while molars receive innervation from the posterior superior alveolar nerve. A distribution claiming only premolars or only molars doesn’t match the standard anterior-teeth pattern. Therefore, the best match is the central incisors, lateral incisors, and canines.
