The length of time for local anesthesia to fail depends mainly on the amount of anesthetic used. Generally, if it is a local minor operation, the anesthetic dose is relatively small, and it will fail in about two or three hours. If the anesthetic dose is relatively large, it may take about six hours to fail.
