Which nerve supplies the anterior maxillary teeth (6-11)?

Explanation:
The front upper teeth are supplied by the anterior superior alveolar nerve, a branch of the infraorbital nerve from the maxillary division of the trigeminal nerve. This nerve travels to the maxillary anterior teeth (the central incisors and canines) and the associated facial gingiva, which corresponds to teeth numbered 6–11 in universal notation. The middle superior alveolar nerve serves the premolars (and the mesiobuccal root of the first molar), the posterior superior alveolar nerve supplies the posterior maxillary teeth, and the nasopalatine nerve supplies the anterior palate and nasal mucosa, not the teeth. So the correct nerve for the anterior maxillary teeth is the anterior superior alveolar nerve.
