Are Root Canals Safe?

The effectiveness of root canal treatment is well-established. However, misinformation continues to circulate on the Internet that may cause patients to question the safety of endodontics. It is in the best interest of patients to understand there is no valid, scientific evidence linking root canals to cancer or other health problems, and also to understand the advancements in modern dentistry that make endodontic treatment predictable, effective and successful.

Myth-Root canal treatment causes illness

The myth: Patients searching the Internet for information on root canals may find sites claiming that teeth receiving root canal (endodontic) treatment contribute to the occurrence of illness and disease in the body. This false claim is based on long-debunked and poorly designed research performed nearly a century ago by Dr. Weston A. Price, at a time before medicine understood the causes of many diseases.

In the 1920s, Dr. Price advocated tooth extraction-the most traumatic dental procedure-over endodontic treatment. This resulted in a frightening era of tooth extraction both for treatment of systemic disease and as a prophylactic measure against future illness.

The truth: There is no valid, scientific evidence linking root canal-treated teeth and disease elsewhere in the body. A root canal is a safe and effective procedure. When a severe infection in a tooth requires endodontic treatment, that treatment is designed to eliminate bacteria from the infected root canal, prevent reinfection of the tooth and save the natural tooth.

  • The presence of bacteria in teeth and the mouth has been an accepted fact for many years. But the presence of bacteria does not constitute “infection” and is not necessarily a threat to a person’s health. Bacteria are present in the mouth and teeth at all times, even in teeth that have never had a cavity or other trauma. Research shows that the healthy immune system takes care of bacteria in a matter of minutes.
  • Tooth extraction is a traumatic procedure and is known to cause a significantly higher incidence of bacteria entering the bloodstream; endodontic treatment confined to the root canal system produces much less trauma and a much lower incidence and magnitude of bacteria entering the blood stream.
  • There is no replacement as good as our natural tooth – it should be saved whenever possible. Root canal treatment, along with appropriate restoration, is a cost effective way to treat infected teeth because it is usually less expensive than extraction and placement of an implant. In most cases, endodontic treatment allows patients to keep their natural teeth for a lifetime.

But what about Dr. Price? This is a good example of how the Internet can give new life to long-dispelled theories. Believe it or not, the misinformation about roots canals that is found on the Internet is still based on Dr. Price’s century-old, discredited research. Dr. Price’s research techniques were criticized at the time they were published, and by the early 1930s, a number of well-designed studies using more modern research techniques discredited his findings. In 1951, the Journal of the American Dental Association took the extraordinary step of publishing a special edition reviewing the scientific literature and shifted the standard of practice back to endodontic treatment for teeth with non-vital pulp in instances where the tooth could be saved. The JADA reviewed Dr. Price’s research techniques from the 1920s and noted that they lacked many aspects of modern scientific research, including absence of proper control groups and induction of excessive doses of bacteria.

As recently as 2013, research published in JAMA Otolaryngology-Head & Neck Surgery, found that patients with multiple endodontic treatments had a 45 percent reduced risk of cancer.
