Root canal treatment (also known as endodontic treatment) is a dental procedure that removes infected or damaged pulp tissue from inside the tooth — the nerves and blood vessels at its core.
The goal is to eliminate infection, relieve pain, and preserve the natural tooth — avoiding extraction wherever possible.
Signs You May Need Root Canal Treatment
A clinical assessment is needed to confirm whether root canal treatment is required.
🦷
Toothache
Persistent or severe pain, especially when biting or chewing.
🌡️
Sensitivity
Lingering sensitivity to hot or cold even after the source is removed.
😮
Swelling
Swelling of the gum or face near the affected tooth.
🦠
Abscess
Pimple-like bump on the gum, sometimes with discharge.
⬛
Discolouration
Darkening of the tooth, which may indicate pulp damage.
✅
Assessment Needed
Only a dental examination can confirm whether treatment is appropriate.
*Clinical assessment is required to determine the appropriate course of treatment for your specific case.
A step-by-step procedure to remove infection and preserve your natural tooth
1
Assessment & X-Ray
Dr Christine examines your tooth and takes an X-ray to assess the extent of infection and confirm suitability for root canal treatment.
2
Local Anaesthesia
The area is numbed with a local anaesthetic. Most patients report little to no discomfort during the procedure itself.
3
Pulp Removal
A small opening is made in the crown of the tooth. The infected pulp tissue — nerves and blood vessels — is carefully removed.
4
Canal Cleaning & Shaping
The root canals are cleaned, disinfected, and shaped to remove all traces of bacteria and infected tissue.
5
Filling & Sealing
The cleaned canals are filled with a biocompatible material (gutta-percha) and sealed to prevent reinfection.
5
Crown Restoration
A dental crown is typically recommended after root canal treatment to restore strength and protect the tooth from fracture.on.
*Treatment timeline and number of visits depend on individual clinical conditions.
Frequently Asked Questions
The procedure is performed under local anaesthesia. Most patients are surprised at how comfortable the treatment is. Some mild soreness after the anaesthesia wears off is normal and typically subsides within a few days.
This depends on the complexity of the case. Some teeth can be completed in a single visit. Others may require two or more appointments, particularly if the infection is severe or the tooth anatomy is complex. The dentist will advise after assessment.
Antibiotics can reduce infection temporarily but cannot remove the infected pulp inside the tooth. Without root canal treatment, the infection will return. A proper clinical assessment is needed to determine the right course of action.
An untreated infected tooth can lead to abscess formation, spreading infection, bone loss, and ultimately tooth loss. Early treatment preserves more of the natural tooth structure.
In most cases, yes. Root canal treated teeth become more brittle over time and are at higher risk of fracture. A dental crown protects the tooth and restores its full function. The dentist will advise based on the specific tooth and its condition.
With proper restoration and good oral hygiene, a root canal treated tooth can last many years — in some cases, a lifetime. Regular dental check-ups help monitor the treated tooth over time.
Preserving a natural tooth is generally preferable to extraction. Natural teeth function better for biting, support surrounding teeth, and maintain jawbone density. Extraction is considered when the tooth cannot be saved. The dentist will always advise the most appropriate option for your case.
