But I don't know how a dentist could possibly tell the nerves are dead before drilling in. And the way they know is that you say ouch that fucking hurts.
- etcet 11y agoThey do hurt you but they don't use a drill at first. I had a root canal done recently and the dentist briefly touched a piece of dry ice to my tooth. He did to a an undamaged tooth first, I guess to see if I could feel pain?
- pnathan 11y agoCorrect. The doc did it to me. I had a very dead tooth, and a very alive tooth. Worked like a charm.
