Few treatments are as misunderstood as the root canal. The truth is that a root canal *relieves* pain — it does not cause it. Here is an honest look at what to expect.
Why the fear is outdated
The "painful root canal" reputation comes from decades ago, before modern anaesthetics and rotary instruments. Today, a root canal is comparable to having a routine filling. The real pain is usually the toothache that brings you in — and that is exactly what the treatment fixes.
What actually causes the pain you feel now
When decay, a crack or trauma reaches the soft pulp inside a tooth, the nerve becomes inflamed or infected. This causes throbbing, sensitivity to hot and cold, and sometimes swelling. Removing that infected tissue is what ends the pain.
The step-by-step procedure
- Diagnosis and X-ray — we confirm the nerve is affected.
- Complete numbing — the tooth and area are fully anaesthetised, so you stay comfortable throughout.
- Cleaning the canals — the infected pulp is gently removed and the canals disinfected.
- Sealing — the canals are filled with a biocompatible material.
- Filling and crown — the tooth is rebuilt, often with a crown to protect it long-term.
After the treatment
Mild tenderness for a day or two is normal and settles with routine painkillers. You can usually return to work the same or next day. Protecting the tooth with a crown helps it last for many years.
If you have a lingering toothache, do not wait — early treatment is simpler and saves the tooth. Learn about our gentle root canal treatment or call us for a same-day emergency slot.
Frequently Asked Questions
Is a root canal painful?
No. The tooth is fully numbed, so the procedure feels similar to a filling. Most patients say the toothache beforehand was far worse than the treatment itself.
How many visits does a root canal take?
Many root canals are completed in a single visit; more complex cases may need two. We advise you based on your specific tooth at the first appointment.
Do I need a crown after a root canal?
Often, yes. A treated tooth can become brittle, and a crown protects it from fracture so it can last for many years.
