Clear, evidence-based information to help you make an informed decision about your tooth.
Misinformation about root canals often repeats claims from an early twentieth-century theory that was later discredited. Modern endodontic care uses current imaging, infection-control practices, and evidence-based techniques. Your treatment decision should still be individualized after an examination and a discussion of benefits, alternatives, and risks.
The AAE reports that decades of research do not support a causal link between properly treated root canal teeth and systemic disease. Many recurring claims rely on the discredited focal infection theory.
When a tooth can be predictably restored, endodontic treatment removes infection while preserving the natural tooth. Extraction may be appropriate in some cases, but it is not automatically the safer option.
Dental claims should be checked against peer-reviewed research, professional associations, and advice from qualified clinicians who can consider your individual history.
The American Association of Endodontists updated its Root Canal Safety Fact Sheet in 2026. The stable safety hub below is the best starting point; the fact sheet and patient myths guide provide more detail.

Root canal treatment is a well-established, evidence-based procedure used to remove infection and preserve a natural tooth. The American Association of Endodontists states that there is no valid scientific evidence linking properly treated root canal teeth with systemic disease. As with any procedure, your endodontist should review the benefits, alternatives, and risks for your specific tooth and health history.
Current evidence does not show that root canal treatment causes cancer or chronic systemic illness. Many claims online trace back to the early twentieth-century focal infection theory, which was based on research methods that were later discredited. If a claim worries you, bring it to a licensed dentist or physician so the source and your individual health history can be reviewed together.
Extraction is not automatically safer. Root canal treatment removes infected tissue while preserving the natural tooth, whereas extraction removes the tooth and may require replacement. The best option depends on whether the tooth can be predictably restored, the extent of infection or damage, and your overall treatment plan.
Write down your concerns and the sources you have seen, then discuss them during an endodontic evaluation. Dr. Anderson can explain the diagnosis, treatment options, expected benefits, alternatives, and material risks before you decide. Online education can help you prepare, but it cannot replace an examination or advice based on your medical and dental history.
An evaluation can clarify the diagnosis, whether the tooth can be saved, and which treatment options fit your situation. Submit a request and our team will contact you to confirm an available time.
