The phrase "root canal" makes people nervous. Most of that fear comes from old stories — or movies. In 2025, a root canal is closer to getting a filling than the ordeal people imagine.
Why you might need one
When the soft tissue inside your tooth (the pulp) becomes infected — usually from deep decay, a crack, or repeated dental work — it can't heal on its own. Left untreated, the infection spreads to the bone and surrounding teeth. A root canal removes the infected pulp, cleans the canal, and seals it so the tooth can stay in your mouth.
The alternative is extraction. Most dentists — and patients — strongly prefer saving the natural tooth.
What actually happens during the procedure
Step 1 — Anaesthesia. The area is numbed with local anaesthetic. You may feel pressure but not pain. If you've been in pain before the appointment, the tooth may take slightly longer to numb — tell your dentist.
Step 2 — Access. A small opening is made through the crown of the tooth to reach the pulp chamber.
Step 3 — Cleaning. The infected pulp is removed using fine files. The canals are cleaned, shaped, and flushed with antiseptic solution.
Step 4 — Filling. The cleaned canals are filled with a material called gutta-percha, which seals them permanently.
Step 5 — Crown. In most cases, a crown is placed over the treated tooth in a separate appointment. This protects the tooth long-term, as root-treated teeth can become brittle.
How long does it take?
A straightforward root canal takes 60–90 minutes. Complex cases (teeth with multiple canals, curved roots) may require two appointments.
Does it hurt afterward?
Mild soreness for 1–3 days is normal, especially if there was an abscess before treatment. Over-the-counter pain relief is usually sufficient. If pain is severe or worsening after 48 hours, contact your dentist.
The bottom line
A root canal done under good local anaesthesia, by a careful dentist, is no more uncomfortable than having a filling. Most patients say they wish they hadn't waited as long as they did.
