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.

May is National Save Your Tooth Month, and tooth decay is a leading cause of lost teeth. It all begins with oral bacteria growing rapidly in built-up deposits of dental plaque, and in turn producing high levels of acid. At these levels, acid can erode the minerals in tooth enamel to create holes (“cavities”) that allow bacteria to enter the tooth and infect it.
If at all possible, we need to try to stop tooth decay early by disinfecting and filling these cavities. If not, decay can spread through the teeth to the underlying nerve (pulp) tissue, following passageways known as root canals. If this happens, the chances for saving the tooth are extremely low.
But if the decay does reach the tooth’s innermost layer—the pulp—filling the cavities won’t be enough. Decay this advanced requires a procedure known as root canal therapy, or a root canal for short.
If you winced a little, it’s understandable: Root canals have gained an unfair reputation as an unpleasant experience. In reality, a root canal performed by a skilled dentist or endodontist (a specialist in root canals) isn’t painful. In fact, if you come in with a painful tooth, you’re very likely to leave after the procedure without any pain.
Root canal procedures can vary depending on the type of tooth and the intricacy of its root canal network. Essentially, though, we remove the diseased pulp tissue, and then clean and fill the empty pulp chamber and root canals. This stops the infection and, along with sealing and crowning the tooth, helps prevent a future re-infection.
How do you know if you need a root canal? You may find out from us if we discover advanced decay during a checkup or cleaning appointment. But you may encounter signs yourself like a throbbing toothache, pain during and after eating and drinking, or gum tenderness around a tooth. These are all possible indications of tooth decay.
If you experience any of these signs, you should see us as soon as possible for an examination. And don’t cancel your appointment if the pain goes away—this could simply mean the nerves in the pulp have died and are no longer transmitting pain signals. The infection, though, could still be there and continuing its rampage beyond the tooth and into the surrounding bone tissue.
Root canal therapy may not seem glamorous, but it’s an excellent option for a diseased tooth that would otherwise have to be removed. A root canal could get rid of your pain and give your troubled tooth a new lease on life!

Most first-time root canal treatments achieve their purpose in saving an internally decayed tooth and extending its life to match those of the patient’s non-decayed teeth. Occasionally, though, a root canal-treated tooth may become re-infected by decay.
There are a number of reasons for this: the permanent crown meant to add further protection against decay may have been delayed, giving bacteria an opening to re-infect the tooth; it’s also possible the original seal for the pulp chamber and root canals after filling wasn’t sufficient to prevent bacterial contamination.
There‘s also another reason that’s very difficult to foresee — the presence of narrow, curved root canals in the tooth that can pose complications during the procedure. Some of these known as accessory or lateral canals branch off the main canals to create a complex network that’s difficult to detect during the initial procedure. If they’re not cleaned out and filled during the procedure any tissue trapped in them can remain infected and ultimately die. If these canals also open into the periodontal membrane at the attachment between the teeth and bone, the infection can spread there and become a periodontal (gum) infection that can trigger future tooth loss.
Fortunately, a reoccurrence of infection isn’t necessarily a death sentence for a tooth. A second root canal treatment can correct any problems encountered after the first treatment, especially complications from accessory canals. It may, though, require the advanced skills of an endodontist, a dental specialist in root canal problems. Endodontists use microscopic equipment to detect these smaller accessory canals, and then employ specialized techniques to fill and seal them.
If you encounter pain or other signs of re-infection for a tooth previously treated with a root canal procedure, contact us as soon as possible. The sooner we can examine and diagnose the problem, the better your tooth’s chances of survival by undergoing a second root canal treatment.

A tooth with deep decay is in real peril. If the disease isn’t stopped, it can eventually infect the bone and greatly increase the risk of losing the tooth. But tooth decay removal and a root canal treatment can stop advancing decay and resulting infection in its tracks.
During this common procedure we first drill into the tooth to access the inner pulp. After removing the infected pulp tissue, we disinfect and fill the empty chamber and root canals with gutta percha. We then seal the tooth and crown it to protect against re-infection.
But while most root canals are successful and long-lasting, sometimes the tooth becomes re-infected. Here are 3 factors that could affect the long-term success of a root canal treatment.
Early treatment. Like many health problems, the sooner we detect decay and treat it, the better the outcome. A tooth in which the infection has already advanced beyond the pulp is at greater risk for re-infection than one in which the infection is localized in the pulp. Keeping up your regular dental visits as well as seeing the dentist at the first sign of abnormality—spots on the teeth or pain—can increase your chances of early diagnosis.
Tooth complications. Front teeth with their single roots and canals are much easier to access and treat than a back molar with an intricate root canal network. Root canals can also be extremely narrow making them easy to miss during treatment. In cases like this the expertise and advanced equipment of an endodontist (a specialist in root canal treatment) could help increase the odds of success in complex situations.
The aging process. Teeth do wear over time and become more brittle, making them increasingly susceptible to fracture. A previous root canal treatment on an aging tooth might also increase the fracture risk. To avoid this, it’s important for the tooth to receive a crown after the procedure to protect the tooth not only from re-infection but undue stress during chewing. In some situations, we may also need to place a post with a bonded composite buildup within the tooth to give it extra support.
Even if a tooth has these or similar complications, a root canal treatment may still be advisable. The benefits for preserving a decayed tooth often far outweigh the risks of re-infection.

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.
