RootCanalsareaSafeWaytoSaveTeeth

Every year U.S. dentists perform around 25 million root canal treatments and save countless teeth from the ravages of decay. But if you search "root canal" on the Internet, you might encounter an unsettling charge against this tooth-saving treatment—that it causes cancer.

Root canal treatments are routinely used when tooth decay has infected the pulp, the innermost layer of a tooth. During the procedure, we access the pulp and remove all the infected tissue. We then fill the empty pulp and root canals, seal the access hole and later crown the tooth to prevent further infection. Without this intervention, the decay can continue to advance toward the roots and supporting bone, putting the tooth in imminent danger of loss.

So, is there any credibility to this claim that root canal treatments cause cancer? In a word, no: there's no evidence of any connection between root canal treatments and cancer—or any other disease for that matter. On the contrary: root canals stop disease.

As with other types of urban legends and internet hype, the root canal-cancer connection may have arisen from another discredited idea from the early 20th Century. A dentist named Weston Price promoted the notion that leaving a "dead" organ in the body led to health problems. From his perspective, a root canaled tooth with its removed pulp tissue fit this criterion.

In the mid-1950s, dentistry thoroughly examined Dr. Weston's theory pertaining to treatments like root canals. The Journal of the American Dental Association devoted an entire issue to it and found after rigorous scientific inquiry that the theory had no validity in this regard. Another study in 2013 confirmed those findings. In fact, the later study instead found that patients who underwent a root canal treatment had a 45 percent reduction in oral cancer risk.

Given the freewheeling nature of the Internet, it's best to speak with a dental professional about your oral health before trusting a post or article you've found online. Not only are they more informed than an unverified online source, they would certainly not knowingly subject you to a procedure to save a tooth at the expense of your health.

RegardlessofWhatYouveSeenOnlineDontFearaRootCanalTreatment

With smart phone in hand, you can instantaneously find out just about anything. Unfortunately, online search results aren’t always accurate. Case in point: there’s an idea floating on the World Wide Web that root canal treatments cause cancer.

Sounds ludicrous? Yes, but like other strange ideas this one has historical roots (pardon the pun). In the early 20th Century, a dentist named Weston Price propagated the idea that leaving a “dead” organ in the body caused health problems. By his view, a root canal-treated tooth fell into this category and could potentially cause, among other things, cancer.

But concern over root canal treatment safety is on shaky ground: dentistry examined Dr. Price’s ideas over sixty years ago and found them wanting. But first, let’s look at what a root canal treatment can actually do for your health.

Tooth decay is an infection that first attacks the outer tooth enamel and then continues to advance until it infects the inner pulp. It can then travel through the root canals to the roots and bone. Without intervention, the infection will result in tooth loss.

We use a root canal treatment to save the tooth from this fate. During the procedure we remove and disinfect all of the diseased or dead tissue within the pulp and root canals. We then fill the empty chamber and canals with a special filling and seal the tooth to prevent any further infection. And while technically the procedure renders a tooth unable to respond to thermal sensitivity or tooth decay, the tooth is still alive as it is attached to the periodontal ligament and its blood supply and nerve tissue. The tooth can still “feel” if you bite on something too hard and it doesn’t affect the tooth’s function or health, or a patient’s overall health for that matter.

As to Dr. Price’s theory, extensive studies beginning in the 1950s have examined the potential health risk of root canal treatments. The latest, a 2013 patient survey study published in a journal of the American Medical Association, not only found no evidence linking root canal treatment to cancer, but a lower risk of oral cancer in 45% of patients who had undergone multiple root canal treatments.

While root canal treatments do have potential side effects, none are remotely as serious as this online “factoid” about cancer. It’s far more likely to benefit your health by saving your tooth.

AnswerstoCommonQuestionsAboutRootCanalTreatments

A root canal treatment is a commonly known but often misunderstood procedure. Contrary to popular belief, these treatments aren't painful — in fact, they often stop a toothache. More importantly, a “root canal” can give a tooth on the verge of loss another lease on life.

Still, if you've never experienced a root canal treatment before, you probably have questions. Here are the answers to a few of the most common.

Why do they call it a “root canal”? This is the popular shorthand term for a procedure that removes diseased tissue from a decay-infected pulp, the innermost part of a tooth and the actual root canals themselves. Root canals are the narrow, hollow channels that run from the tip of the root to the pulp and are also involved in the procedure.

Why do I need one? Once infected, the pulp's bundles of blood vessels, nerves and other tissues become diseased. This often results in a painful toothache that can also suddenly disappear once the nerves within the pulp die. But there's still a problem: If we don't clean out the diseased and dead pulp tissue, the infection could spread through the root canals to the bone and endanger the tooth's survival.

What happens during the procedure? After deadening the tooth and surrounding gums with local anesthesia, we enter the pulp through an access hole we create. Using special instruments we remove the diseased tissue and shape the root canals to seal them with a filling material called gutta percha. Sealing the access hole is then necessary to prevent re-infection. Later we'll cap the tooth with a porcelain crown to restore its appearance and add further protection against fracture or cracking of the tooth.

Who can perform a root canal treatment? In many cases a general dentist can perform the procedure. There are some complex situations, however, that require a root canal specialist with additional training, expertise and equipment to handle these more difficult cases. If your tooth is just such a case it's more than likely your general dentist will refer you to an endodontist to make sure you get the right kind of care to save it.
