Root Canal Therapy
A root canal is a dental procedure where the tooth’s infected or damaged pulp is removed and replaced with a root filling.
phone Book Your VisitSymptoms of tooth pulp damage or disease
A diseased tooth pulp may cause inflammation or infection. The symptoms of a damaged or diseased tooth pulp may include:
- unprovoked or spontaneous pain
- sensitivity to hot and cold drinks and foods
- pain when biting or chewing
- loosening of the tooth
- swelling of the gum near the affected tooth
- oozing of pus surrounding the affected tooth
- facial swelling
Sometimes, tooth pulp may become damaged or diseased without any symptoms. In these cases, the problem is usually diagnosed by special tests or x-rays during a dental check-up or treatment for other dental concerns.

Who needs to get a root canal therapy?
Root canal treatment is needed when dental X-rays show that the pulp has been damaged by a bacterial infection.
The pulp may become inflamed if it’s infected by bacteria, allowing the bacteria to multiply and spread.
The symptoms of a pulp infection include:
- pain when eating or drinking hot or cold food and drink
- pain when biting or chewing
- a loose tooth
As the infection progresses, these symptoms often disappear as the pulp dies.
Your tooth may appear to have healed temporarily, but the infection could continue spreading through the root canal system if untreated.
You may eventually experience further symptoms, such as:
- pain when biting or chewing returning
- swelling of the gum near the affected tooth
- pus oozing from the affected tooth
- a swollen cheek or jaw
- the tooth becoming a darker colour
It’s important to see your dentist if you develop toothache. If your tooth is infected, the pulp cannot heal by itself. Leaving the infected tooth untreated may worsen the condition.
Root canal treatment is most effective when performed before the infection becomes established.

Frequently Asked Questions
1. What is a microscopic root canal treatment?
It is a root canal procedure performed using a high-powered dental operating microscope (DOM). The microscope provides 3x to 30x magnification and bright, co-axial lighting, allowing the endodontist to visualize the intricate internal structure of the tooth, including tiny, hidden, or calcified canals, in high definition.
2. How does it differ from traditional (conventional) root canal treatment?
While conventional treatment relies on the naked eye, loupes, or tactile sense, microscopic RCT provides a vastly superior view.
- Precision: It enables the detection of extra canals (like the MB2 in upper molars), which are often missed in traditional methods (17% detection without magnification vs. ~71% with a microscope).
- Minimally Invasive: Because the dentist can see exactly where to drill, less healthy tooth structure is removed, preserving the strength of the tooth.
- Troubleshooting: It allows for the safe removal of broken instruments and the repair of perforations, which might otherwise lead to tooth extraction.
3. Why is using a microscope so important?
The root canal system is complex and, in some areas, as thin as a human hair. Missed canals are a primary cause of failed root canals and persistent infection. The microscope ensures all canals are thoroughly cleaned and disinfected, greatly increasing the success rate.
4. What are the key benefits for the patient?
- Higher Success Rates: Up to 94% success, particularly in complex cases or retreatment.
- Reduced Pain/Complications: Because the procedure is more precise, there is less damage to surrounding tissues, resulting in less post-operative discomfort and faster healing.
- Better Preservation: More natural tooth structure remains.
- Documentation: Many microscopes have cameras, allowing you to see high-definition images of your own treatment.
5. Is the procedure painful?
No. Microscopic root canals are performed under local anesthesia, just like traditional root canals. Because the dentist can work more efficiently, the time spent in the chair is often reduced.
6. When is a microscope-assisted root canal required?
It is especially crucial for complex cases, such as:
- Root canal retreatment (fixing a previous, failed root canal).
- Calcified or blocked canals.
- Teeth with unusual or complex anatomy.
- Locating hairline cracks or fractures.
7. Is a microscope-assisted root canal more expensive?
While the initial cost may be higher than a traditional root canal due to the advanced technology, it is often more cost-effective in the long run because it prevents the need for future retreatment or tooth extraction.
8. Will it take longer than a normal root canal?
Not necessarily. The enhanced visualization allows for greater efficiency, though sometimes the ability to find complex, hidden, or extra canals might lead to a more thorough (and thus potentially longer) procedure, ensuring the tooth is saved correctly the first time
Can a tooth pulp be damaged without causing pain?
- A: Yes, sometimes the tooth pulp becomes damaged or diseased without any symptoms, and the problem is diagnosed via special tests or X-rays during a check-up.
