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.

The internet has transformed how we get information. Where you once needed to find an encyclopedia, telephone directory or library, you can now turn to your handy smartphone or tablet for the same information.
But this convenience has a dark side: A lot of material online hasn’t undergone the rigorous proofreading and editing published references of yesteryear once required. It’s much easier now to encounter misinformation—and accepting some of it as true could harm your health. To paraphrase the old warning to buyers: “Viewer beware.”
You may already have encountered one such example of online misinformation: the notion that undergoing a root canal treatment causes cancer. While it may sound like the figment of some prankster’s imagination, the idea actually has a historical basis.
In the early 20th Century, a dentist named Weston Price theorized that leaving a dead anatomical part in the body led to disease or major health problems. In Price’s view, this included a tooth that had undergone a root canal treatment: With the vital pulp removed, the tooth was, in his view, “dead.”
Price amassed enough of a following that the American Dental Association rigorously investigated his claims in the 1950s and found them thoroughly wanting. For good measure, a Journal of the American Medical Association (JAMA Otolaryngology—Head & Neck Surgery) published a study in 2013 finding that not only did canal treatments not increase cancer, but they might even be responsible for decreasing the risk by as much as forty-five percent.
Here’s one sure fact about root canal treatments—they can save a tooth that might otherwise be lost. Once decay has infiltrated the inner pulp of a tooth, it’s only a matter of time before it spreads through the root canals to the bone. Removing the infected pulp tissue and filling the resulting empty space and root canals gives the tooth a new lease on life.
So, be careful with health advice promoted on the internet. Instead, talk to a real authority on dental care, your dentist. If they propose a root canal treatment for you, they have your best health interest—dental and general—at heart.

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.

Children have a lot of energy that's often channeled through physical activities and sports. Unfortunately, this also increases their risk of injuries, particularly to their teeth.
Injuries to the mouth can endanger permanent teeth's survival. For an older tooth, a root canal treatment might be in order. Not so, though, for a pre-adolescent tooth, even if it is permanent.
A young permanent tooth is still developing dentin, the large layer just below the enamel. This growth depends on the connective tissue, blood vessels and nerves within the pulp in the center of the tooth. Because a root canal treatment removes all of this tissue, it could stunt dentin and root growth and endanger the tooth's future.
Instead, we may need to treat it with one of a number of modified versions of a root canal, depending on what we find. If the tooth's pulp is unexposed, for example, we may need only to remove the damaged dentin, while still leaving a barrier of dentin to protect the pulp. We then apply an antibacterial agent to minimize infection and fill in the area where we've removed tooth structure.
If some of the pulp is exposed, we may perform a pulpotomy to remove just the affected pulp and any overgrown tissue. We then place a substance that encourages dentin growth and seal it in with a filling. If we go deeper toward the root end, we might also perform procedures that encourage the remaining pulp to form into a root end to stabilize the tooth.
If the entire pulp has been damaged beyond salvage, we may then turn to a procedure called an apexification. In this case we clean out the pulp chamber; at the root end we place mineral trioxide aggregate (MTA), a growth stimulator that encourages surrounding bone to heal and grow. We then fill in the root canals and chamber with a special filling called gutta percha to seal the tooth.
The deeper we must penetrate into the pulp, the higher the chances the young tooth's dentin and roots won't form properly, leading to later problems and possible loss. But by employing the appropriate one of these methods, we can minimize the risk and give your child's damaged tooth a fighting chance.
