Root canal treatment is one of the most commonly misunderstood dental procedures. It’s often associated with pain or fear, but modern techniques and anaesthesia mean that, for many people, treatment is more comfortable than expected.
Root canal therapy is generally performed to help manage infection or inflammation inside a tooth and may allow a tooth to be retained rather than removed.
1. What is a root canal?
Inside each tooth is a soft tissue called the pulp, which contains nerves and blood vessels. Deep decay, cracks, trauma, or repeated dental work can cause this pulp to become inflamed or infected.
Root canal treatment (also called endodontic therapy) aims to:
- Remove infected or damaged pulp tissue
- Clean and disinfect the inside of the tooth
- Seal the root canals to reduce the risk of reinfection
After treatment, the tooth is restored with a filling and sometimes a crown, depending on the tooth’s structure and function. This helps protect the tooth and support long-term use.
2. Signs you might need a root canal
Symptoms vary between individuals. Some people experience obvious discomfort, while others have no symptoms and the issue is detected during a dental check-up.
Common signs include:
- Toothache (especially when chewing or applying pressure)
- Sensitivity to hot or cold that lingers
- Darkening of the tooth
- Swelling or tenderness in the gums
- A pimple-like bump on the gum near the tooth (sometimes called a sinus tract)
It’s important to note that these symptoms can be caused by other dental issues as well. A dentist can assess the cause through examination and X-rays.
3. Is root canal treatment painful?
For many people, modern root canal treatment is performed under local anaesthetic, meaning the tooth and surrounding area are numbed.
During the procedure, you may feel:
- Pressure or vibration
- Movement from instruments
- Mild discomfort, depending on the tooth and inflammation level
After treatment, it’s common for the tooth to feel tender for a few days. This can often be managed with pain relief recommended by your dentist or pharmacist.
Everyone’s experience differs, and your dentist can discuss pain management options if you are anxious or concerned.
4. The root canal process – step by step
Root canal treatment is often completed in one or two visits, depending on the tooth and the severity of infection.
Step 1: Diagnosis and planning
Your dentist may take X-rays to assess the tooth and surrounding bone and discuss treatment options, which can include:
- Root canal treatment
- Extraction
- Monitoring (in limited cases)
Step 2: Access and cleaning
To protect the tooth during the procedure, the dentist isolates it to keep it dry and minimise contamination. Then:
- A small opening is made in the tooth
- Infected pulp tissue is removed
- The canals are cleaned, shaped, and prepared
Step 3: Disinfection and filling
The canals are disinfected using dental solutions, then filled with a biocompatible material (commonly gutta-percha) and sealed.
Step 4: Final restoration
The tooth is restored with a filling or, in many cases, a crown to help reduce the risk of fracture and maintain chewing function.
5. Why not just remove the tooth?
Extraction can be the right option in some situations, particularly if the tooth is too damaged to restore. However, removing a tooth may lead to other considerations, such as:
- Changes to chewing function
- Movement of surrounding teeth over time
- The potential need for replacement (e.g., bridge, denture, or implant)
Clarity Dental dentist will explain the benefits and risks of each option based on your tooth’s condition and your overall oral health.
6. How much does a root canal cost?
The cost of root canal treatment can vary depending on:
- Which tooth is being treated (front teeth generally have fewer canals than molars)
- Complexity of the case
- Whether treatment is performed by a general dentist or an endodontist
- Whether a crown or additional restoration is required
In Bendigo, dental care is commonly privately funded, though private health extras may contribute depending on your level of cover.
It may be helpful to request:
- A detailed written quote
- Item numbers to check rebates with your health fund
- An estimate that includes both the root canal procedure and the final restoration (if required)
7. Aftercare and long-term maintenance
Following treatment, your dentist will advise you on how to care for the tooth while it heals.
To help protect the tooth:
- Avoid chewing on the treated tooth until advised
- Attend for final restoration (such as a crown) if recommended
- Maintain consistent brushing and flossing
- Keep up regular dental check-ups and professional cleans
While root canal treatment can be effective, outcomes vary depending on factors such as the tooth’s condition, the extent of infection, and ongoing oral hygiene. In some cases, further treatment may be needed.
8. Final thoughts
Root canal treatment is often recommended to manage infection or inflammation and may allow a tooth to remain functional rather than being removed.
If you’ve been advised to have a root canal, you can ask your dentist to:
- Explain the diagnosis and show you the X-rays
- Outline the steps involved
- Discuss alternatives and likely outcomes
- Provide a clear breakdown of expected costs
Understanding what is happening can help reduce anxiety and support informed decision-making.
