You may have heard the rumor that getting a root canal could increase your risk of developing cancer. This myth has been circulating for decades, causing unnecessary fear around an important dental procedure. In reality, root canals are completely safe and play a vital role in preserving natural teeth. Here’s the truth behind the myth—and why you have nothing to worry about.
Where Did This Myth Come From?
The misconception that root canals cause cancer can be traced back to a study conducted in the early 1900s by Dr. Weston A. Price. At the time, dentistry and microbiology were still developing fields, and Dr. Price’s research methods would not meet modern scientific standards. His claims suggested that bacteria trapped in a root canal–treated tooth could spread and lead to serious diseases like cancer. However, these conclusions have long since been disproven by contemporary research.
Modern endodontic techniques and sterilization standards have completely eliminated the concerns raised in those outdated studies. Today’s root canal procedures are highly precise, safe, and effective, supported by decades of scientific evidence and clinical success.
What Does the Science Actually Say?
There is absolutely no scientific link between root canal therapy and cancer. In fact, multiple studies and reputable health organizations—including the American Association of Endodontists (AAE), the American Dental Association (ADA), and the National Institutes of Health (NIH)—have confirmed that root canals do not cause cancer or any other systemic illnesses.
Root canal treatment is designed to remove infection, not create it. The procedure eliminates harmful bacteria from inside the tooth, disinfects the area, and seals it to prevent reinfection. By doing so, it actually helps protect your oral and overall health by stopping the spread of infection that could otherwise cause serious complications.
Why Root Canals Are Perfectly Safe
Thanks to modern dental technology, root canal treatment today is both safe and comfortable. Dentists use advanced imaging, sterile instruments, and biocompatible materials to ensure that the tooth is completely cleaned and sealed. Local anesthesia and improved techniques make the experience no more uncomfortable than getting a standard filling.
Beyond being safe, root canals are often the best way to save a natural tooth that would otherwise need extraction. Keeping your natural tooth in place helps preserve jawbone density, maintain proper bite alignment, and prevent neighboring teeth from shifting.
The Real Risks of Avoiding Treatment
Avoiding a root canal out of fear can have serious consequences. If an infected tooth isn’t treated, the infection can spread to other parts of the body, leading to pain, swelling, and even potentially life-threatening complications. By choosing to move forward with treatment, you’re not just saving your tooth—you’re protecting your health.
