If a dentist has mentioned root canal treatment, it’s normal to feel anxious. Understanding what it is — and why it’s recommended — usually makes it feel much more manageable.

Signs you may need root canal treatment

  • Pain to hot or cold that lingers after the food or drink is gone
  • Spontaneous throbbing pain, especially at night
  • Pain when biting or touching the tooth
  • A gum boil or swelling near one tooth
  • A tooth that has darkened after an injury

Sometimes there are no symptoms at all and infection is spotted on an X-ray during a check-up.

Common myths

“Root canals are extremely painful.”

The treatment is done with local anaesthetic. It is usually the infection beforehand that is painful; treatment aims to relieve it.

“It’s better to just pull the tooth.”

Sometimes extraction is the right choice, but keeping a natural tooth has advantages, and replacing a missing tooth adds time and cost. Your dentist will explain both options.

What happens during treatment

After an X-ray and numbing, the dentist makes a small opening, removes the inflamed pulp, cleans the canals and seals them. The tooth is then restored, often with a crown. It may take one to three visits.
