Are Root Canals Safe?
There are people that insist that root canals are not a safe procedure and that no one should ever
have one. These people refer to a study done in the early 1900's of Dr. Weston Price. This study concluded
that infected material and bacteria are left in the tooth and continue to infect the body after the root
canal is finished, therefore infection remains in the tooth and surrounding jaw bone.
The dental community has been accused of everything from total ignorance of this situation, to
deliberately covering up these conclusions.
The American Association of Endodontists (AAE)
website, http://www.aae.org/patients/mythsrootcanal/ has this to say on the subject:
"Root canal treatment 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 the presence of illness. Instead,
researchers found that people with root canal fillings were no more likely to be ill than people without
Over the past several years, however, a very small number of dentists and physicians have
been claiming that teeth that have received root canal (endodontic) treatment contribute to the occurrence of
illness and disease in the body. This claim is based on the outdated research performed by Dr. Weston Price
from 1910-1930. His research stated that bacteria trapped in the teeth during root canal treatment can cause almost
any type of disease, including arthritis, heart disease, kidney disease, and 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
More recent attempts to copy the research of Dr. Price (and to check its accuracy) have been
unsuccessful. Researchers now believe that the earlier findings may have been caused by poor sanitation and
imprecise research techniques that were common in the early 1900s.
These more recent studies support the truth we report today—that teeth that receive proper
endodontic treatment do not cause illness."
