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 extractionthe most traumatic dental procedureover 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 requiresendodontic treatment, that treatment is designed toeliminatebacteria from the infected root canal,preventreinfection of the tooth andsavethe natural tooth.
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. Prices century-old, discredited research. Dr. Prices 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, theJournal of the American Dental Associationtook 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. TheJADAreviewed Dr. Prices 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.
Nothing can completely replace your natural tooth. An artificial tooth can sometimes cause you to avoid certain foods. Keeping your own teeth is important so that you can continue to enjoy the wide variety of foods necessary to maintain the proper nutrient balance in your diet. If your dentist recommends extraction, ask whetherroot canal treatmentis an option.
Endodontic treatment, along with appropriate restoration, is a cost-effective way to treat teeth with damaged pulp and is usually less expensive than extraction and placement of a bridge or an implant.
Millions of healthy endodontically treated teeth serve patients all over the world, years and years after treatment. Those healthy teeth are helping patients chew efficiently, maintain the natural appearance of their smiles and enhance their enjoyment of life. Through endodontic treatment, endodontists and dentists worldwide enable patients to keep their natural teeth for a lifetime.
