Myths vs Facts

Root Canal Treatment: Still Think It's the Most Painful Procedure?

Dr. N. Mani Sundar11 March 20263 min read

Say "root canal" and watch people wince. It's become a cultural shorthand for unbearable pain — in Tamil cinema, English movies, and everyday conversation. But here's the truth: a root canal relieves pain, it doesn't cause it.

The Myth

"Root canal treatment is extremely painful and should be avoided as long as possible."

The Reality in 2026

  • Modern anaesthesia works: With today's local anaesthetics, you won't feel the procedure. Most patients at our clinic say it feels similar to getting a filling.
  • The pain is from the infection, not the treatment: By the time you need a root canal, the nerve inside your tooth is infected or dying. That's what causes the throbbing agony. The root canal removes the source of pain.
  • Rotary instruments = faster & smoother: We use advanced rotary endodontic systems — not the slow, manual files of 20 years ago. Treatment that once took 3 visits now often takes just one.
  • Delaying is dangerous: An untreated infected tooth can lead to an abscess, jawbone infection, or even sepsis in rare cases. The small discomfort of treatment is nothing compared to these risks.

What a Root Canal Actually Feels Like

Here's what our patients typically report: numbness during the procedure (you'll feel pressure but not pain), mild soreness for 2–3 days after (managed with basic painkillers), and then — complete relief from the toothache that brought them in.

Patient Perspective: "I avoided the dentist for 2 years because I was scared of root canal. When I finally came to Dr. Mani Sundar, the whole thing took 45 minutes and I didn't feel a thing. I wish I hadn't waited." — Priya, Velachery
