Can confirm.

My lips and gums go numb but my teeth generally do not. I am sure it takes the edge off, but I can still feel it and it is still incredibly uncomfortable.

On the other hand, while having a tooth pulled and opting to be put under, the nurse and I were having a great laugh after because I was so awake. Apparently there are multiple drugs and whatever the first one was hit me so hard they only have me a half dose of another. It was enough though. They said count, I hit nine, and I woke up somewhere else. Exactly what I wanted considering local doesn't work.
