Root canal treatment

When the inside of a tooth is infected or inflamed, root canal treatment cleans and seals it, relieving pain and saving the tooth instead of removing it.

Saving teeth

What it is

Inside every tooth is the pulp — soft tissue with nerves and blood vessels. Deep decay, a crack, a knock or repeated dental work can let bacteria reach it, causing inflammation, pain or an abscess. Root canal treatment removes the infected pulp, cleans and shapes the canals inside the root, and fills and seals them so bacteria can't return.

Modern root canal treatment is done under local anaesthesia and feels much like having a filling. It relieves pain rather than causing it. Afterwards, a tooth that has lost a lot of structure is often protected with a crown so it stays strong for chewing.

Suitable for

  • Lingering toothache or sensitivity to hot and cold
  • Pain when biting, or a swollen gum
  • A dental abscess or deep decay
  • A cracked or injured tooth

Root canal treatment

How it's done

  1. 01

    Diagnosis

    We examine the tooth and take X-rays to see the shape of the roots and the extent of the infection.

  2. 02

    Cleaning the canals

    Under local anaesthesia, a small opening is made and the infected pulp is removed.

  3. 03

    Shaping and disinfecting

    The canals are cleaned and shaped. A temporary filling may protect the tooth between visits.

  4. 04

    Sealing and restoring

    The canals are filled and sealed, and the tooth is restored with a filling or a crown.

Aftercare

Every treatment starts with a consultation. The information here is general — your dentist will tell you what applies to you.

  • Your mouth may stay numb for a few hours — avoid eating until it wears off
  • Some tenderness for a few days is normal; ibuprofen or paracetamol help
  • Avoid chewing hard foods on that tooth until it's fully restored
  • Come back for the crown or final filling if one is planned
  • Contact us if swelling or pain gets worse instead of better

Questions

Questions, answered.

  • With local anaesthesia it feels similar to a filling. Most people feel relief afterwards, because the source of the pain has been removed.

  • Keeping your natural tooth is almost always better for chewing, appearance and the bone around it. A missing tooth would later need an implant or bridge.

  • Often, especially for back teeth or teeth with large fillings. A crown protects the tooth from cracking.
