What you may have heard

Bacteria left behind during a root canal procedure can release toxins into the bloodstream and lead to cancer. This idea has gained attention through online forums and alternative health documentaries.

What the science tells us

Root canals are not linked to cancer. This myth originated from a discredited theory over 100 years ago and has been thoroughly debunked by modern research. According to Penn Dental Medicine, root canals are safe, effective procedures that treat infection and preserve natural teeth. Avoiding treatment can lead to serious dental problems, including pain, swelling, tooth decay, damage, and tooth loss.

Epidemiological Evidence

There is no credible scientific evidence supporting any connection between root canals and cancer.

How to reduce your risk

Maintain good oral hygiene and visit a dentist regularly. Prompt treatment of dental infections, including root canals when needed, protects your overall health.

Bottom line

Root canals do not cause cancer. They are a routine, safe procedure used to treat infection and preserve natural teeth.
