Episode 773: Why Inferior Alveolar Nerve Blocks Fail: Common Causes and Clinical Fixes
|
 |
In this episode, we go back to the fundamentals. We explore why the inferior alveolar nerve block fails so often, what’s really happening anatomically when patients aren’t getting numb, and how a deeper understanding of these patterns can help clinicians improve both consistency and patient comfort in everyday practice. We’ll also take a closer look at anesthetic selection—specifically the advantages of articaine over lidocaine—and discuss the clinical situations where articaine can make a meaningful difference, and why many clinicians consider it an essential part of their anesthetic armamentarium. Joining us today is Dr. David Isen. He practices in Toronto, Canada, where his anesthesia-based practice focuses on patients who require all levels of sedation, general anesthesia, and advanced local anesthetic techniques—often individuals with special medical needs, dental phobia, or unique challenges with anesthesia.
