An inferior alveolar nerve block is administered to patients who require dental work in the mandible. Injection of local anesthetics (e.g., lidocaine) into the oral mucosa at the lingula of the mandible will anesthetize the inferior alveolar nerve and potentially the proximal lingual nerve, resulting in numbness of the tongue and oral mucosa. Care must be given when extracting the third molar tooth because the lingual nerve is closely associated with this nerve.

A plexus formed by the anterior superior, middle superior, and posterior superior alveolar nerves supplies the maxillary teeth. Unlike the mandibular teeth, where anesthesia can be administered in one location to effectively block all the teeth on that side, the maxillary teeth must be considered separately. The palate must also be considered; therefore, a greater palatine as well as a nasopalatine nerve block is often administered during dental procedures.

Maxillary molars. Injection is given at the region of the sec ond molar.

Maxillary premolars. Injection is given at the region of the second premolar.

Maxillary canine and incisors. Injection can be given above the roots of the anterior teeth or via an infraorbital nerve block.
