What Does the Research Say?

Modern scientific research and major dental and medical organisations agree that there is no credible evidence linking Root Canal Treatment to cancer. The Canadian Cancer Society states clearly: “There is no evidence that root canals cause cancer.”  Earlier theories originated from flawed research nearly a century ago and have long been disproven.  

Today’s dental practices ensure infection is removed, the tooth is sealed and sterilised, and the risk of complications is minimal. According to the American Association of Endodontists, the claim of causation between root canals and systemic diseases like cancer is unsupported.  

Why the Myth Persists

Even though the scientific consensus is clear, the notion that root canals cause cancer continues to circulate. This is due to historical misconceptions, anecdotal stories and misunderstanding of how dental infections can impact health.

Common Reasons for the Misconception

• Historical research errors: Early 1900s experiments by Weston A. Price suggested that root-canal treated teeth harboured toxins and could contribute to systemic illnesses, including cancer. These studies were not conducted in a controlled or sterile environment.
• Coincidental timing: Some patients who have had root canal treatment later develop cancer — this temporal correlation is mistaken for causation when no direct link exists.  
• General fear of dental treatment: Complex treatments generate anxiety and misinformation, which often leads to myths about outcomes and safety.

What Are the Real Risks of Root Canal Treatment?

While root canals do not cause cancer, like any medical or dental procedure they carry some limited risks. Understanding these helps patients make informed choices.

Realistic Risks and Considerations

• Post-treatment infection: Although rare, an implant might fail or infection may persist, requiring retreatment.  
• Structural weakness: A treated tooth may need adequate restoration (crown) to regain full strength and avoid fracture.
• Sensitivity or discomfort: Some patients may feel temporary sensitivity or mild discomfort after treatment — this is distinct from systemic disease.
