What Is Root Canal Treatment?
Inside every tooth is a soft tissue called the pulp, which contains nerves, blood vessels, and connective tissue. When this pulp becomes infected — through deep decay, a crack, or repeated dental procedures — it can cause significant pain and, if left untreated, may lead to an abscess.
Root canal treatment (also called endodontic treatment) involves removing the infected or damaged pulp, cleaning and shaping the inside of the root canals, and filling them with a biocompatible material. This allows you to keep your natural tooth rather than having it extracted.
The treatment is performed under local anaesthetic. Contrary to common perception, modern root canal treatment is typically no more uncomfortable than having a filling placed.
Signs You May Need Treatment
- Persistent or severe toothache
- Prolonged sensitivity to hot or cold
- Darkening or discolouration of a tooth
- Swelling or tenderness in the surrounding gum
- A recurring pimple (sinus tract) on the gum
- Pain when biting or chewing
These symptoms do not always indicate the need for root canal treatment. A clinical examination and X-rays are required for proper diagnosis.
The Treatment Process
Root canal treatment is usually completed in 1–2 appointments.
Diagnosis & X-rays
We take X-rays to assess the extent of infection and plan the treatment. The procedure, risks, and alternatives are discussed with you.
Anaesthesia & Access
The tooth is numbed with local anaesthetic. An opening is made in the crown of the tooth to access the infected pulp chamber.
Cleaning & Shaping
The infected pulp tissue is carefully removed using specialised instruments. The canals are cleaned, shaped, and disinfected.
Filling & Restoration
The cleaned canals are filled with a biocompatible material (gutta-percha). A crown may be recommended to protect the treated tooth.
Aftercare Instructions
How to care for your tooth after root canal treatment.
Do
- Take any prescribed antibiotics or pain relief as directed
- Eat on the opposite side until the permanent restoration is placed
- Maintain good oral hygiene — brush gently around the treated area
- Attend your follow-up appointment for the permanent filling or crown
- Contact us if pain worsens or swelling develops after 48 hours
Avoid
- ✕ Chewing on the treated tooth until the permanent restoration is fitted
- ✕ Hard or crunchy foods in the first few days
- ✕ Extremely hot or cold food and drinks for 24–48 hours
- ✕ Smoking, which can slow the healing process
- ✕ Delaying the follow-up crown appointment — the temporary filling is not a long-term solution
Risks & Considerations
All dental procedures carry some risks. These are discussed during your consultation.
Re-infection
In a small percentage of cases, infection may return and retreatment or surgical intervention may be needed.
Tooth Fracture
Root-treated teeth can become more brittle. A crown is often recommended to reduce the risk of fracture.
Missed Canal
Some teeth have additional or unusually shaped canals that can be difficult to detect, potentially requiring retreatment.
Discolouration
Root-treated teeth may darken over time. This can be addressed with internal bleaching or a crown if needed.

Patient Experiences
Relieving Persistent Pain
A patient presented with a severe toothache that had been keeping them awake at night. X-rays revealed infection at the root of a molar. Root canal treatment was carried out over two appointments, and the tooth was subsequently restored with a crown. At their six-month review, the patient reported no further pain and was pleased to have kept their natural tooth.
Individual results may vary. Treatment outcomes depend on individual circumstances.
Saving a Discoloured Tooth
A patient noticed one of their front teeth had gradually become darker in colour. Examination revealed that the nerve inside the tooth had died following an old injury. Root canal treatment was performed, followed by internal bleaching and a porcelain veneer to restore the tooth's appearance.
Individual results may vary. Aesthetic outcomes depend on individual factors.
