Root canal treatment is one of the most talked-about dental procedures, yet it’s also one of the most misunderstood. Many patients form strong opinions about root canals long before they ever need one, often based on things they’ve heard from friends, family, or online searches rather than real clinical experience. As a result, fear and hesitation can build around a treatment that is actually designed to stop pain and protect natural teeth.
Much of the confusion comes from outdated beliefs that no longer reflect how modern dentistry works. Techniques, technology, and pain control have changed dramatically, but the stories have not. This gap between perception and reality causes some patients to delay treatment unnecessarily, which can lead to worsening infection, increased discomfort and avoidable tooth loss.
This article breaks down the most common root canal myths and replaces them with clear, factual explanations. By understanding what is true and what is not, patients can make informed decisions about their oral health without fear, misinformation or unnecessary anxiety.
Key Takeaway
Most root canal myths are outdated or false; modern root canal treatment is comfortable, safe and one of the best ways to save a natural tooth.
Why Root Canal Myths Still Exist
Root canal myths still exist in the community at large due to exaggerated patient stories and reliance on old dental techniques that are no longer used in modern dentistry. Decades ago, dentistry was less advanced, and pain management was not as effective as it is today.
Contributing factors include:
- Stories passed down from older generations
- Confusion between infection pain and treatment pain
- Fear of dental procedures in general
- Misinformation online
Modern dentistry has transformed root canal treatment into a predictable, comfortable procedure.
💡Most fears of a root canal procedure stem from old and outdated information. It’s not based on latest developments in dentistry.
Myth 1: Root Canal Treatment Is Extremely Painful
This is the most common myth – and it’s not true at all. A root canal procedure relieves pain, it doesn’t cause pain. Modern root canal treatment:
- Uses effective local anaesthetic
- Removes the source of infection and inflammation
- The procedure can feel not that dissimilar to having a dental filling for many patients
The pain most patient’s associate with a root canal procedure usually is a result of the infection within the tooth, not as a result of procedure itself.
💡 Treating the infection deep down in the tooth pulp stops the pain. It doesn’t create pain.
Myth 2: It’s Better To Extract The Tooth Than Have A Root Canal On The Tooth

Some patients mistakenly think that an extraction is easier and also perhaps safer than saving your natural tooth. However, this is not usually true.
Saving a natural tooth:
- Maintains proper bite alignment
- Prevents neighbouring teeth from shifting
- Preserves jawbone structure
- Avoids more complex future treatments
Extraction of the tooth will often require additional treatment down the line – such as an implant or a dental bridge.
💡 Preserving your natural tooth is usually the healthiest option.
Myth 3: Root Canal Treatment Takes Many Appointments
A few cases – those that are complex in nature – can require multiple visits. However a significant proportion of them are usually finished in one appointment.
Treatment time depends on:
- Tooth location
- Number of canals
- Severity of infection
Advances in imaging and techniques have significantly reduced treatment time.
💡 Many root canal procedures often take less time that the patient might have expected.
Myth 4: Root Canals Can Cause Illness In Other Parts Of The Body
This myth dates back a very long time. And it has been completely and utterly debunked. Modern research shows:
- No link between root canals and systemic disease
- Properly treated teeth are safe to keep
- Infection removal improves overall health
If you leave a tooth that is infected untreated, this can pose a bigger risk to your health.
💡 Scientific evidence supports root canal safety.
Myth 5: Root Canal Is Only Needed When You Have Severe Pain
Not all infections in the tooth cause you pain. This is especially true in the early stages of infection.
A tooth may still need treatment if:
- The nerve has died
- Infection is present without symptoms
- There is visible damage on X-rays
Waiting for pain can allow infection to worsen.
💡 Not experiencing any pain does not imply there is no infection.
Myth 6: Root Canals Weaken Teeth Permanently
A tooth that has been treated with a root canal is saved from extraction and can function normally for a long time if properly restored.
Strength is restored through:
- Protective fillings or crowns.
- Removal of infection that weakens structure
- Ongoing oral hygiene
The treatment itself does not weaken the tooth.
💡 Restoration is key to long-term strength.
Myth 7: Root Canals Don’t Last Long
Success rates of root canal treatment are very high when done by an experienced root canal specialist. Long-term success depends on:
- Proper cleaning and sealing
- Timely placement of a crown if needed
- Good oral hygiene
Many root-canal-treated teeth last decades or longer.
💡Maintenance plays a big role in longevity.
Myth 8: You Will Need To Take Time Off For Days After A Root Canal Procedure
Most individuals return to their usual routine within 24 hours of the procedure. Post-treatment expectations include:
- Mild tenderness for a short time.
- Normal eating after numbness wears off
- Minimal disruption to daily life
Severe pain after treatment is uncommon.
💡Recovery is usually quick and manageable.
Myth 9: Root Canals Is Only Needed For Older Adults
Root canal procedure could be required for patients of any, depending on the patient’s oral health or dental trauma.
Young children, teenagers and grown ups – all may need treatment as a result of:
- Deep decay
- Accidents or injuries
- Developmental issues
Age does not determine the need for treatment.
💡 Tooth health matters more than age.
Myth 10: Antibiotics Can Replace Root Canal Treatment
Antibiotics alone cannot remove infected pulp tissue.
Antibiotics may:
- Temporarily reduce symptoms
- Help control spreading infection
However, the infected tissue is the main cause needs to be removed in order to address the problem.
💡 Root canal treatment addresses the root cause of the issue, not just its symptoms.
Myth 11: Root Canal Always Requires A Crown On The Tooth After

Not every tooth will need a dental crown after a root canal procedure. However, many posterior teeth will benefit from having one.
Crown recommendations depend on:
- Tooth location
- Amount of remaining structure
- Bite forces
Front teeth often do not require crowns.
💡Restoration is tailored to each tooth.
Myth 12: Root Canals Are Risky Procedures
When performed by trained professionals, root canal treatment is highly predictable and safe.
Safety is ensured through:
- Modern imaging
- Sterile techniques
- Advanced instruments
Complications are uncommon.
💡 Choosing experienced care reduces risks further.
Myth 13: Root Canal Treatment Is Too Expensive To Be Worth It
While treatment has a cost, it often prevents more expensive procedures later.
Comparisons show:
- Root canal plus crown often costs less than extraction plus replacement
- Preserving a tooth avoids future complications
Value should be measured long term.
💡 Saving a tooth is often more economical over time.

Dentistry has evolved significantly in recent decades. Improvements include:
- Better anaesthetics
