## Overview Infraorbital nerve block is a regional anesthetic used for dental procedures on the upper incisors and canine teeth. Because the nerve supplies the upper lip, the block temporarily causes lip droop and mild difficulty eating on that side. The effect resolves as the local anesthetic wears off, usually within a few hours. ## Causes Intentional local anesthesia for dentistry. ## Diagnosis History of recent dental nerve block and transient lip asymmetry. ## Treatment None required. The effect is temporary. Soft feed may be easier until sensation returns. ## Recovery and Prognosis Excellent. Full function returns within hours. ## Prevention Not applicable (expected effect of the block).
