With whatever he did additionally, as he did it he goes:
“Let’s try this again, start counting back from 10”
I might have made it to 9 the second time around.
Does this mean they messed up the dosage or something? I’ve had the same guy since and it’s never happened again.
The fact that he gave you something else that time, and that you've never had that experience again would make me believe he thought it was a fault in the product he initially gave you.
That's not what they usually use... but people have different reactions to novacaine, and different innervation; for dental work, there's a couple typical options for where nerves are and which nerves cover which teeth, some of which need more shots in more places.
For the GP, most likely the anesthetist put a note in the chart that they need more or different drugs to go under.
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.
