In a few years I think we will look back on how today's dentists look after teeth with shock, similar to how we do now knowing that they used to treat depression with a frontal lobotomy. "They used to DRILL your teeth? And if that didn't work they yanked them out of your jaw?" It all seems so low tech.
People still get their wisdom teeth taken out without being put under. I heard one person describe the process inside your mouth sounding like a tree trunk being snapped in half.
I've had 4 wisdom teeth removed with local anaesthetic. I felt absolutely nothing during the procedures, though the sound of my teeth being hammered into pieces (two were lodged horizontally and had to be manhandled) was certainly unnerving.
After it was done I got up and got home, no side effects. I have no idea why it's apparently so common for a general anaesthetic in the US. (On the other hand, without it we wouldn't have hundreds of YouTube videos featuring hilariously rambling, drugged-up teens.)
