Root canal therapy causes illness

Truth - Root canal therapy is a safe and effective procedure.

Research studies performed in the 1930s and 1940s and those conducted in later years showed no relationship between the presence of endodontically treated teeth and illness. Instead, researchers found that people with root canal fillings are no more likely to be ill than people without them.

However, over the past several years, a very small number of dentists and physicians have claimed that teeth that have received root canal (endodontic) therapy contribute to the occurrence of illness and disease. This claim is based on the outdated research performed by  Dr. Weston Price from 1910-1930. His research stated that bacteria trapped in teeth during root canal treatment can cause almost any type of disease, including arthritis, heart disease, kidney disease amongst others.

The presence of bacteria in teeth and mouth has been an accepted fact for many years. But 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.

Recent attempts to duplicate the research Dr. Price's results were unsuccessful. Researchers now believe that the earlier findings were caused by poor sanitation and imprecise research techniques that were common in the early 1900s.

These recent studies support the fact - that teeth that with proper endodontic therapy do not cause illness.
