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.

Along with periodontal (gum) disease, tooth decay poses one of the two greatest threats to your teeth. Cavities are just the start: if decay invades the pulp, the tooth’s innermost layer, the infection created can continue to advance through the root canals to the supporting bone. This worst case scenario could cost you your tooth.
But we can stop this advanced decay in its tracks with a procedure called a root canal treatment. A root canal essentially removes all the infected tissue within the tooth and then seals it from further infection. And contrary to its undeserved reputation for being painful, a root canal can actually stop the severe tooth pain that decay can cause.
At the beginning of the procedure, we deaden the affected tooth and surrounding tissues with local anesthesia—you’ll be awake and alert, but without pain. We then isolate the tooth with a dental dam of thin rubber or vinyl to create a sterile environment around it to minimize contamination from bacteria found in saliva and the rest of the mouth.
We then drill a small hole through the enamel and dentin to access the interior of the tooth. With special instruments, we remove and clean out all the diseased or dead tissue in the pulp chamber and root canals. After disinfecting the empty spaces with an antibacterial solution, we’ll shape the root canals to make it easier to perform the next step of placing the filling.
To fill all the root canals and pulp chamber, we typically use a rubber-like material called gutta-percha. Because it’s thermoplastic (“thermo”—heat; “plastic”—to shape), we can compress it into and against the walls of the root canals in a heated state to fully seal them. This is crucial for preventing the empty tooth interior from becoming re-infected. Afterward, we’ll seal the access hole with its own filling; later, we’ll bond a permanent crown to the tooth for additional protection and cosmetic enhancement.
After the procedure you may have some temporary minor discomfort usually manageable with aspirin or ibuprofen, but your nagging toothache will be gone. More importantly, your tooth will have a second chance—and your dental health and smile will be the better for it.

Root canal treatment can be an effective life preserver for a heavily decayed tooth. The question a lot of people ask, though, is how long might the tooth survive after treatment.
That’s an important concern since the treated tooth was in dire straits beforehand as decay had infected its inner most layer, the pulp. The infection, which had caused the living bundles of nerves, blood vessels and connective tissue within to become inflamed and diseased, was poised to invade even deeper through the root canals. During the root canal treatment, the infected pulp tissue is removed and the empty chamber and root canals are filled with a special filling to seal the tooth from further infection.
The protection, though, isn’t an absolute certainty: how long a treated tooth survives depends on a number of factors. For one, the earlier a diseased tooth can be initially diagnosed — especially if the infection hasn’t spread into the jawbone — the better the procedural outcome. Likewise, the chances of longevity are also better if the initial root canal treatment was thorough in identifying and filling all the root canals as well as capping the tooth with a life-like crown in a timely manner after treatment.
The type and location of the tooth can also affect its long-term health. Front teeth, with their single roots and canals are easier to access and treat. Back teeth, by contrast, can have two or more roots and a more intricate canal network. These kinds of complications could require the use of special microscopic equipment and the expertise of an endodontist, a specialist in root canals.
Even if a re-infection occurs, the tooth isn’t necessarily lost. A repeat root canal treatment that addresses these and other issues, could give the tooth a “third” chance. In any case, if a tooth is worth saving attempting a root canal treatment is generally preferable to losing the tooth and replacing it with a prosthetic tooth — it’s well worth the try.

So, you've undergone a root canal treatment to save a decayed tooth. The tooth has a new lease on life — and the pain is gone too. But there's a reality you need to keep in mind — your tooth could become re-infected, putting you back in the same painful circumstance.
Root canal treatments are often necessary when decay works its way deep within a tooth, into the pulp. The excruciating pain a person feels is the infection attacking the bundle of nerves within the pulp tissue. If the infection isn't addressed promptly, it will continue to work its way to the root, eventually damaging the tooth beyond repair.
During a root canal treatment, we drill into the tooth to access the pulp chamber. After clearing it completely of its infected tissue, we then fill the chamber and root canals with a special filling and then seal off the access. A short time later we'll bond a crown over the tooth to protect it and to make it more attractive.
Most of the time, this preserves the tooth for many years. Occasionally, though, re-infection can occur. There are a number of reasons why: the first infection may have been more extensive than thought; the root canal network was more complex and some tinier canals weren't able to be identified; or the protective crown may once again get tooth decay contaminating the root canal.
If infection does reoccur it doesn't mean the tooth is lost. It's possible a second root canal treatment can successfully correct any problems, especially those that may not have been detected the first time. More complex cases might also require the services of an endodontist, a specialist in root canals. They're skilled in advanced techniques and have specialized equipment to handle even the most complicated root canal networks.
In the meantime, if you notice signs of re-infection like pain or swelling around a treated tooth, contact us promptly for an appointment. You should also contact us if the tooth is injured in an accident. The sooner we can treat your tooth, the more likely the second time will be more successful.
