Root canals, demystified: why they're painless today
Dr. Sudhagar06 Jun, 2026· 12,110 views
Few treatments have a worse reputation than the root canal — and few deserve it less. With modern rotary instruments and better anaesthesia, a root canal today feels much like a routine filling.
What a root canal actually does
When decay or injury reaches the soft pulp inside a tooth, it becomes infected and painful. A root canal removes that infected tissue, disinfects the canals and seals them — ending the pain while keeping your natural tooth in place.
The procedure relieves the pain you arrived with; it does not cause it.
After your treatment
- Mild tenderness for a day or two is normal
- A crown is usually recommended to protect the tooth
- Your tooth can last a lifetime with good care
