Why root canals got such a bad reputation
The pain people associate with root canals almost always actually comes from the infected or inflamed tooth itself before any treatment even happens — deep, throbbing pain, sharp sensitivity to pressure, and sometimes visible swelling around the affected area. The procedure itself is genuinely what relieves that pain, not what causes it in the first place, but the negative association unfortunately stuck around for decades anyway regardless of how the actual treatment has improved since then. Older techniques and equipment from decades ago genuinely earned some of that reputation at the time, which is worth remembering when the topic comes up in conversation and the old jokes start flying.
