Failure of inferior alveolar nerve block: exploring the alternatives

Achieving proper anesthesia is imperative to performing most dental procedures. The conventional inferior alveolar nerve block is the most commonly used nerve block technique. In certain cases, however, this nerve block fails, even when performed by the most experienced clinician.

The authors explore the reasons why the conventional inferior alveolar nerve block fails and describe several alternate techniques. They also present the protocol used in their office to achieve mandibular anesthesia.

Several alternatives to the inferior alveolar nerve block are available. Clinicians should investigate them, rather than repeat the inferior alveolar nerve block after it has failed. Practice Implications. Mastering anesthetic techniques maximizes success in the dental office. It enables clinicians to provide better and more comfortable treatment to patients.
