Just hearing “root canal” can make people nervous — but do they really hurt? Let’s clear up the myths and explain what really happens during a root canal.
😬 First, Why Do People Fear Root Canals?
Root canals have a scary reputation because:
- People confuse the pain before the treatment with the procedure itself
- Old stories from decades ago (before modern numbing techniques) still linger
- The idea of drilling deep into a tooth just sounds painful
But here’s the good news…
✅ Modern Root Canals Are Not Painful
Today’s root canals are usually no more painful than getting a filling. Dentists use powerful local anaesthesia to numb the area, so you won’t feel pain during the procedure.
At most, you’ll feel:
- Pressure or movement
- A little soreness after (like after a dental cleaning or filling)
🔍 What Happens During a Root Canal?
- Numbing – Your dentist applies a local anaesthetic
- Cleaning – The infected pulp inside your tooth is removed
- Shaping – The inside of the root canals is cleaned and shaped
- Filling – The canals are filled with a special material
- Restoration – A crown or filling is placed on top
🕒 It usually takes 1–2 visits, depending on the case.
🤕 What About After the Treatment?
It’s normal to feel some tenderness for a few days:
- Your jaw might be sore from keeping your mouth open
- The treated tooth may feel sensitive
This usually goes away with:
- Over-the-counter painkillers (like paracetamol or ibuprofen)
- Avoiding hard foods for a few days
🧠 Fun Fact: It’s Pain RELIEF, Not Painful
In most cases, you need a root canal because the tooth is already causing pain. The procedure actually removes the pain source by clearing the infection or damaged nerve.
🏥 When to See a Dentist
You might need a root canal if you experience:
- Persistent toothache
- Pain when chewing or biting
- Sensitivity to hot/cold
- Swollen gums near a tooth
- A darkening tooth
Don’t wait — early treatment means less pain, faster recovery, and better outcomes.
👍 In Summary
Myth | Truth |

The recovery takes weeks | Most people feel better in 1–3 days |
