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.
Local anesthetic only, was a lot of work and as the surgeon got his leg up to get leverage I could feel my front teeth moving a little from the pressure.
