It's not an exaggeration to say the modern root canal treatment has saved millions of teeth over the last century. Without this procedure, there's not a lot we can do to stop advanced tooth decay from infecting and destroying a tooth.
What's more, a root canal treatment could extend the life of a tooth for decades. Notice we said could—although most root canals do have satisfactory outcomes, there's still a chance a tooth may become re-infected. Here are 3 possible causes for an unsuccessful root canal treatment, and what you can do to lessen their impact.
The severity of the infection. Tooth decay usually begins at the enamel layer, softened by the acid produced by bacteria. Untreated, the infection can then spread through the next tooth layer of dentin until finally infecting the innermost pulp. From there the infection can move through the root canals to the bone, dramatically increasing the danger to the tooth. Root canal treatments have a higher chance of success the earlier they're performed in the disease progression, so see your dentist at the first sign of pain or other tooth abnormality.
The root canal network. An effective root canal procedure eliminates all dead or diseased tissue in both the pulp chamber and the root canals (these are then filled to prevent future infection). But this may prove difficult with teeth that have intricate root canal networks because of a higher risk of overlooking some of the canals. It may be best in such cases for an endodontist, a specialist in treating interior tooth issues, to perform the procedure using their advanced techniques and microscopic equipment.
The age of the tooth. Root canal treatment can weaken a tooth's structural integrity, especially with older teeth. This can make them more susceptible to fracture and a higher chance of infection. We can avoid this outcome by placing crowns on root-canaled teeth: The crown provides structural strength to the tooth and can add further protection against infection. Older teeth may also benefit from the placement of a small support post within it to further add stability before applying the crown.

Root canal treatments have suffered a bad rap over the years—and undeservedly. While we applaud root canal therapy for the millions of decayed teeth the procedure has saved, the worn-out cliché that it's painful still lingers on.
So, let's set the record straight: a root canal treatment doesn't cause pain, it most often relieves it. Let's look a little closer at what actually happens before, during and after this tooth-saving treatment.
Before: a tooth in crisis. Tooth decay can damage more than a tooth's outer enamel. This aggressive bacterial infection can work its way into a tooth's interior, destroying the nerves and blood vessels in the pulp, before moving on to the roots and supporting bone through the root canals. Untreated, this devastating process can lead to tooth loss. A root canal treatment, however, can stop the invading decay and save the tooth.
During: stopping the disease. The dentist first numbs the tooth and surrounding gum tissues with local anesthetic—the only thing you might normally feel during treatment is a slight pressure. They then drill into the tooth to access the inner pulp and root canals and remove all diseased tissue. Once the interior spaces of the tooth have been disinfected, the dentist then fills the empty pulp chamber and root canals with a pliable filling called gutta percha to prevent future infection.
After: preventing re-infection. With the filling complete, the dentist then seals the access hole. There may be some minor soreness for a few days, similar to the aftermath of a routine filling, which can usually be managed with over-the-counter pain relievers like ibuprofen. Sometime later, the dentist will normally finish the treatment with a new crown on the tooth. This accomplishes two things: It helps strengthen the tooth against stress fracturing and it provides another layer of protection against future decay.
Root canal treatments have an exceptional track record for giving diseased teeth a second chance. There's nothing to fear—and everything to gain for your troubled tooth.

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.

Primary (baby) teeth might not last long, but their impact can last a lifetime. Their first set of teeth not only allows young children to eat solid foods, but also guide permanent teeth to form and erupt in the proper position.
Unfortunately, primary teeth aren't immune to tooth decay. If the decay is extensive, the tooth may not last as long as it should. Its absence will increase the chances the permanent teeth won't come in correctly, which could create a poor bite (malocclusion) that's costly to correct.
If a primary tooth is already missing, we can try to prevent a malocclusion by installing a “space appliance.” This keeps nearby teeth from drifting into the empty space intended for the permanent tooth. The best approach, though, is to try to save a primary tooth from premature loss.
We can often do this in much the same way as we would with a permanent tooth — by removing decayed material and filling the prepared space. We can also perform preventive applications like topical fluoride or sealants that strengthen or protect the tooth.
It becomes more complicated, though, if the pulp, the interior of the tooth, becomes decayed. The preferred treatment for this in a permanent adult tooth is a root canal treatment. But with a primary tooth we must also consider the permanent tooth forming below it in the jaw and its proximity to the primary tooth. We need to adapt our treatment for the least likely damage to the permanent tooth.
For example, it may be best to remove as much decayed structure as possible without entering the pulp and then apply an antibacterial agent to the area, a procedure known as an indirect pulp treatment. We might also remove only parts of the pulp, if we determine the rest of the pulp tissue appears healthy. We would then dress the wound and seal the tooth from further infection.
Whatever procedure we use will depend on the extent of decay. As we said before, our number one concern is the permanent tooth beneath the primary. By focusing on the health of both we can help make sure the permanent one comes in the right way.

You’ve recently learned one of your teeth needs a root canal treatment. It’s absolutely necessary: for example, if you have decay present, it will continue to go deeper within the tooth and it will spread to the roots and bone and could ultimately cause you to lose your tooth. Although you’re a little nervous, we can assure you that if we’ve recommended a root canal treatment, it’s the right step to take for your dental health.
There’s nothing mysterious — or ominous — about a root canal. To help ease any fears you may have, here’s a step-by-step description of the procedure.
Step 1: Preparing your mouth and tooth. We first take care of one of the biggest misconceptions about root canals: that they’re painful. We completely numb the tooth and surrounding tissues with local anesthesia to ensure you will be comfortable during the procedure. We isolate the affected tooth with a thin sheet of rubber or vinyl called a rubber dam to create a sterile environment while we work on the tooth. We then access the inside of the tooth — the pulp and root canals — by drilling a small hole through the biting surface if it’s a back tooth or through the rear surface if it’s in the front.
Step 2: Cleaning, shaping and filling the tooth. Once we’ve gained access we’ll clear out all of the dead or dying tissue from the pulp and root canals, and then cleanse the empty chamber and canals thoroughly with antiseptic and antibacterial solutions. Once we’ve cleaned everything out, we’ll shape the walls of the tiny root canals to better accommodate a filling material called gutta-percha, which we then use to fill the canals and pulp chamber.
Step 3: Sealing the tooth from re-infection. Once we complete the filling, we’ll seal the access hole and temporarily close the tooth with another filling. Later, we’ll install a permanent crown that will give the tooth extra protection against another infection, as well as restore the tooth’s appearance.
You may experience some mild discomfort for a few days after a root canal, which is usually manageable with aspirin or ibuprofen. In a week or so, you’ll hardly notice anything — and the tooth-threatening decay and any toothache it may have caused will be a distant memory.
