Quick question for everyone here. Have you ever faced a situation where you gave an inferior alveolar nerve block and it seemed to be effective with expected signs and symptoms with lip numb, etc. But when you start reflecting a flap in the premolar region, the patient experienced pain? I just faced this, and I assumed that the inferior alveolar nerve bifurcated higher than the level of my original block, so I gave a second at a higher level. But this did not solve the problem. How do I overcome this with a different injection protocol to get the premolar region numb?
