Dental patients have amazing options for tooth replacement. Dental implants, for example, can replace the entire tooth, root and crown, giving patients a new tooth nearly as good as the old one.
Nearly—but not exact. Even implants can't match the full benefits of a natural tooth, including one in less than perfect shape. Our first goal as dentists, then, is to save a diseased tooth if at all practical before considering replacing it.
That often involves a root canal treatment to address decay threatening a tooth's interior. The procedure requires drilling into the tooth to access its innermost pulp, cleaning out the pulp and root canals, and then filling the empty spaces. Since all dentists are trained in basic root canal treatment, your general dentist may be able to perform it.
But some dental situations call for more advanced endodontics, the dental specialty for treating disease and other problems inside a tooth. So, in what situations would you see an endodontist?
When your dentist refers you. Your dentist wants you to receive the level of treatment necessary to save your tooth. After examination, they may determine your situation would be better served by the advanced training, equipment and techniques (including surgery) of an endodontist.
When your tooth has complications. Patients often need an endodontist when existing factors complicate treatment of advanced tooth decay. A patient may have dental pain that's difficult to pinpoint, requiring the diagnostic resources of an endodontist. It's also common for a tooth's root canal network to be highly intricate, and which respond better to treatment with specialized endodontic tools and techniques.
When root canal treatment fails. Most root canal treatments are successful in protecting the tooth from further infection. That said, it's still possible for a root-canaled tooth to become re-infected or develop more problems. Again, an endodontist and their “tool chest“ re-treating a root-canaled tooth may be the best option for saving it.
You also don't have to wait for a referral—you can see an endodontist if you believe they would be best to treat your decayed tooth. You can find one near you by visiting an online endodontist directory at www.aae.org/find. An endodontist may be the lifesaver your diseased tooth needs.
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.

If you’ve ever read online that root canal therapy causes cancer, don’t be alarmed—it doesn’t. What it does do is save a deeply decayed tooth that might otherwise be lost.
Tooth decay is caused by acid produced by bacteria, which dissolves enamel to create a hole or cavity. But it doesn’t stop there: decay can move on to infect the tooth’s innermost layer, the pulp filled with nerves and blood vessels. Unchecked, the resulting infection can travel through the root canals to eventually infect the bone.
A root canal treatment stops the infection before it goes this far. After administering a local anesthetic, we drill a small hole into the tooth to access the pulp chamber and root canals. We then remove all the diseased tissue, disinfect the space and then place a filling within the empty chamber and root canals to prevent further infection. We then seal the access hole and later crown the tooth to further protect and stabilize it.
It’s no exaggeration, then, to say that root canal treatments have saved millions of teeth. So, for all its beneficial effect, why is it considered by some to pose a health danger?
The germ for this notion comes from the early 20th Century when a dentist named Weston Price theorized that leaving a “dead” organ in place would harm the body. Since a root-canaled tooth with the pulp’s living tissue removed is technically no longer viable, it fit the category of “dead” tissue. Thus, according to this theory, maladies like cancer could arise because of the “dead” tooth.
Unfortunately, this theory has found a somewhat new life recently on the internet, even though it was thoroughly investigated and debunked in the 1950s. And as late as 2013, a study published in a journal of the American Medical Association found no increased cancer risk after root canal treatment, and even some evidence for a reduced risk.
So, if your dentist recommends root canal treatment, rest assured it’s needed to save your tooth. Rather than harm your health, it will improve it.

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.
