Inferior Alveolar Block:
The most common complaint I get from patients regarding Local Anesthesia on the lower arch is that their lip felt numb but they still felt the pain when the dentist drilled on the teeth!
This happens because the operator administered the Long Buccal Nerve Block before verifying that the Inferior Alveolar Nerve Block has kicked in. There are 2 essential steps to do so:
1) Always use a long needle.
2) Don't start injecting till 90% of the needle is in the Pterygomandibular Space and you have hit bone.
3) Ensure that the side of the lower lip is numb EXACTLY to the middle. I also verify with an explorer in the canine area.
4) Do not adminster the Long Buccal Nerve Block till #1,2 and 3 have been completed!
