@kdfrawg The last time I had a tooth extracted, they used nitrous oxide as the anesthetic. I'm glad that they did, because the root was curved at the end, and the oral surgeon had to use a surgical saw to cut into my jawbone in order to extract the tooth. The sound it made was interesting. That's generally how my dental procedures go--with unexpected twists and great difficulty. As the song goes, "I wanna be sedated." :-)
