Root Canal Treatment: Myths, Facts, and Why It’s a Safe Option for Saving Teeth

Root Canal treatments have been the subject of many myths and misconceptions over the years. Some of these misunderstandings stem from outdated studies, while others are fuelled by anecdotal stories or misinformation spread online. Unfortunately, this confusion often leads to unnecessary fear, preventing people from accessing a procedure that is both safe and effective.

When it comes to health and dental care, emotions play a big role in decision-making. We all know someone who has shared a “horror story” about the dentist, and such stories can leave lasting impressions. But it’s important to separate anecdotal claims from peer-reviewed scientific evidence. Avoiding a Root Canal due to misinformation can put your oral and overall health at risk.

Untreated tooth infections can spread, affecting nearby teeth, the jawbone, and, in severe cases, other parts of the body. Pain worsens, abscesses may form, and systemic infections can occur if treatment is delayed.

Let's explore:

• What a Root Canal actually involves
• Why the procedure is performed
• Where the myths came from
• Alternatives to Root Canal treatment
• The pros and cons of extraction versus saving the tooth

By understanding the facts, you’ll see that a Root Canal is not something to fear but a vital tool in preserving oral health.

What is a Root Canal?

A Root Canal is a dental procedure designed to save a tooth that is badly decayed, damaged, or infected. One of the most persistent myths is that a tooth treated with a Root Canal becomes “dead” and can cause health problems in the body. This simply isn’t true.

Instead, the procedure transforms the tooth into a strong, functional structure that remains safe and stable within the mouth.

Step 1: Removing the Diseased Pulp

Every tooth contains pulp at its centre, which holds blood vessels, nerves, and connective tissue. When this pulp becomes infected or inflamed due to decay or trauma, it causes severe pain and swelling. During a Root Canal, the diseased pulp is carefully removed, stopping the infection at its source.

Step 2: Thorough Cleaning and Sterilisation

After removing the pulp, the dentist cleans and disinfects the canals of the tooth. Advanced sterilisation methods ensure that harmful bacteria are eliminated. This step is critical for preventing reinfection.

Step 3: Filling and Sealing the Canals

Once cleaned, the empty space inside the tooth is filled with a safe, biocompatible material such as gutta-percha. This material seals the canals and prevents bacteria from re-entering.

Step 4: Restoring the Tooth

Finally, the tooth is restored with a filling or crown to provide long-term strength and protection. After treatment, the tooth functions normally for chewing and speaking, just like any other tooth.

Why Get a Root Canal?

• Pain relief: Eliminates infection and relieves the severe pain caused by inflamed pulp.
• Preserves natural structure: Saves the natural tooth, which is always preferable to extraction.
• Prevents infection spread: Stops bacteria from spreading to other teeth, bone, or soft tissue.
• Protects appearance and oral health: Maintaining natural teeth prevents gaps, bone loss, and misalignment.

Where Did the Myths Come From?

Much of the fear surrounding Root Canals comes from the work of Dr. Weston Price in the 1920s. He suggested that Root Canal-treated teeth could contribute to systemic illness. However, his research was flawed, poorly designed, and quickly debunked by later studies.

By the 1950s, well-conducted scientific research confirmed that his conclusions were invalid. Modern peer-reviewed studies show no link between Root Canal treatments and systemic diseases like cancer, heart disease, or arthritis.

Health organisations worldwide — including the American Association of Endodontists (AAE) and the American Dental Association (ADA) — endorse Root Canal treatment as safe and effective.

Alternatives to Root Canal Treatment

The main alternative is tooth extraction.

Pros of Tooth Extraction:

• Immediate removal of a painful or infected tooth
• Necessary if the tooth is too damaged to repair
• Lower upfront cost compared to Root Canal treatment

Cons of Tooth Extraction:

• Creates a visible gap in the smile, affecting appearance and confidence
• Can lead to shifting of adjacent teeth, bite issues, and jawbone loss
• Tooth replacement (implants, bridges, dentures) adds to long-term cost and complexity

While extraction may be necessary in extreme cases, dentists generally prefer to save the natural tooth whenever possible.

Root Canal vs. Extraction: A Comparison

Root Canal

• Relieves pain
• Preserves natural tooth
• Natural smile maintained
• Preserves jaw bone
• Cost is higher than an extraction, but is cost-effective long term
• Maintains normal chewing and speaking

Extraction

• Relieves pain
• Tooth lost
• Gap in smile unless replaced
• Risk of jaw bone loss
• Lower cost than root canal, but replacement costs can be high
• Replacement require for return of function

Scientific Evidence Supporting Root Canal Safety

• Infection Elimination: Studies confirm that Root Canal treatment effectively removes infection and prevents further spread.

• Systemic Health: No scientific evidence links Root Canals to other diseases.

• Modern Materials & Techniques: Advances like rotary endodontics, 3D imaging, and improved sealing materials make the procedure more successful and comfortable.

• High Success Rates: Peer-reviewed journals consistently report long-term success for properly performed Root Canals.

A Root Canal is not something to fear — it’s a proven, effective way to save natural teeth and eliminate infection. The idea that Root Canal-treated teeth are “dead” or harmful is based on outdated, debunked research. In reality, the procedure transforms an infected tooth into a stable, safe, and functional part of your mouth.

While tooth extraction remains an alternative, it often leads to additional dental work, higher long-term costs, and oral health complications. Preserving the natural tooth through Root Canal treatment is almost always the best option for both dental and general health.

If you ever come across claims online suggesting Root Canals are unsafe, always consider the source. Look for scientific evidence and professional recommendations, not just anecdotes. And remember — if your dentist suggests a Root Canal, it’s to save your tooth, stop infection, and protect your health.

FAQs About Root Canal Treatment

2. How long does a Root Canal last?

With proper care and a crown if needed, a Root Canal-treated tooth can last a lifetime.

3. Can a Root Canal cause illness?

No. Peer-reviewed scientific research has found no evidence linking Root Canals to systemic diseases.

4. What are the signs I might need a Root Canal?

Severe toothache, prolonged sensitivity to hot/cold, swelling, tenderness, or a darkened tooth may indicate the need for treatment.

5. Is extraction better than a Root Canal?
