There are many believable myths and misconceptions surrounding root canal treatment (RCT) that often cause people to fear it.
However, the truth, supported by modern Australian dental data and advancements, shows that a root canal is one of the most effective and conservative procedures available to save your natural teeth.
Root canal treatment is the gold-standard solution for patients suffering from a severely infected, decayed, or diseased tooth. The primary purpose of the root canal is to save your natural tooth, making tooth extraction the absolute last resort.
If you need treatment for a damaged tooth, especially a molar or premolar that is crucial for chewing, understanding the facts below will show you why a root canal is often the superior, long-term choice for your oral health and dental function.
Debunking the Myths with Australian Data
The misconceptions about RCT are far from the reality in modern dental practice. Let’s look at the facts and figures used by Australian dentists and endodontic specialists.
Myth 1: Root Canal Treatment Can Make You Ill
This outdated myth stems from poorly conducted, unscientific research from the 1920s. Today, the reality is the complete opposite: Root canal treatment is designed to prevent illness. By thoroughly removing all bacteria and infection from the inner pulp chamber and root canals, the procedure eliminates a source of chronic infection that, if left untreated, could lead to:
- A painful abscess at the tooth root.
- The spread of bacteria to other parts of the body, potentially causing serious systemic issues like endocarditis (a heart infection), particularly in at-risk patients.
Myth 2: Root Canal Treatment Offers No Long-Lasting Results
This is a significant misconception that often leads people to consider extraction prematurely. The reality is that modern RCT techniques offer outstanding longevity, especially when paired with a quality restoration.

Treatment Outcome |
Success Rate (Over 10 Years) |
|
Primary Root Canal Treatment (RCT) |
90% – 95% |
|
RCT with Dental Crown (Final Restoration) |
Up to 98% |
|
Dental Implant (for comparison) |
Approx. 90.9% |

In Australia, root canals have a very high success rate. The most common reasons for a root canal “failing” are preventable, such as not placing a final dental crown or having a poor restoration that allows bacterial leakage. An infected tooth becomes brittle once the pulp is removed; therefore, a crown is essential, as it provides the necessary strength and seal.
Myth 3: Tooth Extraction Is a Better or Cheaper Option
While extraction is a quick fix for pain, it is detrimental to your long-term dental health. Saving your natural tooth is almost always the preferred option by Australian dentists. Let’s compare the long-term impact:
|
Factor |
Root Canal Treatment |
Tooth Extraction (without replacement) |
|
Natural Tooth |
Preserved (maintains natural chewing, look, and feel) |
Lost (creates a gap in your smile) |
|
Jawbone Health |
Preserved (the root stimulates the bone) |
Degrades (can lead to up to 25% bone loss in the first year) |
|
Bite Alignment |
Maintained (prevents adjacent teeth from shifting) |
Disrupted (causes teeth to shift and tilt, leading to alignment issues) |
|
Total Long-Term Cost |
Higher upfront cost (e.g., $2,000 to $3,400 for the RCT, plus crown) |
Lower upfront cost (e.g., $135 to $500 for simple extraction) but potentially much higher long-term cost if replaced. |

The upfront root canal cost may seem high, but when you factor in the inevitable cost of replacing an extracted tooth with an implant (often over $3,500 for the implant and crown in Australia) or a bridge to prevent jawbone degeneration and tooth shifting, the total long-term cost-effectiveness almost always favours the root canal. Think of RCT as an investment in a highly functional, natural asset.
Myth 4: Root Canal Treatment Is Painful and Uncomfortable
Modern dental technology has made this myth completely obsolete. The pain you feel is from the infected pulp; the root canal procedure itself is conducted under a local anaesthetic and is typically no more uncomfortable than getting a standard filling.
- The treatment instantly relieves the pain by removing the source of the infection.
- The use of advanced techniques and instruments, such as rotary nickel-titanium files and operating microscopes (common in specialist endodontics practices), makes the procedure faster, more efficient, and highly predictable.
- Patients report minimal soreness for a few days post-treatment, which is easily managed with over-the-counter pain relief like Nurofen or Panadol.
Key Takeaways for Your Oral Health
Choosing root canal treatment means choosing to retain your natural teeth, an asset invaluable to your lifelong health and function. In Australia, endodontic specialists and general dentists are highly trained to ensure the procedure is successful, comfortable, and provides excellent longevity.
Early treatment significantly increases the chances of a successful outcome. If you are experiencing tooth pain, prolonged sensitivity to hot or cold, or have a small pimple-like bump on your gum (a sign of a tooth abscess), it is crucial to seek professional help immediately. Delaying treatment can turn a straightforward RCT into a more complex procedure or, worst case, result in the need for an unavoidable tooth extraction.

FAQ
1. Is a root canal painful?
No. Modern RCT is done under local anaesthetic and feels similar to a filling. It actually relieves pain by removing the infection.
2. How successful is root canal treatment?
Very successful—90–95%, and up to 98% when finished with a dental crown.
3. Why do I need a crown after a root canal?
A crown strengthens and protects the tooth, preventing cracks and reinfection.
4. Is extraction cheaper than a root canal?
Upfront yes, but long-term no. Missing teeth lead to bone loss, shifting teeth, and expensive replacements like implants.
5. Can a root canal make me sick?
No. This myth is outdated. RCT removes infection and prevents it from spreading.
6. How do I know if I need a root canal?
Signs include ongoing pain, sensitivity to hot/cold, swelling, or a pimple-like bump on the gum.
7. How long does a root canal last?
With a good crown and proper care, root-canal-treated teeth can last 10+ years, often for life.
