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.

It’s absolutely critical to stop tooth decay and repair any damage to tooth structure. Hopefully, we’ve caught it early in the enamel and dentin where we’re able to repair any holes or “cavities” that might have developed by filling them.
But what if the decay has crept deeper into the interior of the tooth? In this case, you’re at a much higher risk of eventually losing the tooth. If the decay has spread into the bone, a root canal treatment is usually your best option.
The first sign that decay has invaded the pulp, the innermost layer of the tooth, and the root canals may be a severe toothache. It’s different from the wince of pain or discomfort caused by sensitivity to temperature or pressure. Inner decay pain is constant and often excruciating. This is because the infection is attacking the nerves bundled within the pulp chamber.
The pain can last for several days, and then suddenly stop altogether. No pain is good news, right? Wrong — the pain has stopped because the infected nerves have finally died and can no longer signal the brain. The infection, though, is very much alive and will continue to advance toward the root where the damage may eventually cause you to lose the tooth.
A root canal treatment removes decay in the pulp chamber and canals. We first drill an access hole to enter the pulp chamber. Once inside, we use special instruments to completely remove all tissue and disinfect the empty chamber. We then fill the chamber and root canals with a special filling and seal the access hole to prevent further decay. A few weeks later we install a custom crown to protect the tooth further.
If you have a toothache, or you’ve had one that suddenly went away, you should schedule an appointment for a dental examination as soon as possible: this is the only way to accurately determine the cause of the pain. If a root canal is deemed necessary, the sooner we perform it, the less chance the infection will cause you to lose your tooth.

Tooth decay can wreak more havoc than just producing cavities. It can work its way into the innermost parts of the tooth — the pulp and tiny passageways called root canals that lead to the tooth's connection with the bone.
If that happens, you'll need more than “drilling and filling.” Without intervention, your tooth could be lost. That intervention is a root canal treatment, a procedure that removes the infection from within the tooth and preserves it from re-infection.
You've probably heard the old belief that root canal treatments are painful. With modern anesthetic techniques to deaden pain, that's not true. In fact, root canal treatments stop the pain caused by infected nerves within the pulp and root canals. More importantly, it saves your tooth.
Root canals can be performed by a general dentist. More extensive decay or complex root canal networks may require the services of an endodontist, a dentist who specializes in root canal anatomy and treatments. Endodontists have advanced techniques and equipment to handle even the most difficult case.
Regardless of who performs it, the basic procedure is the same, as is the goal: to completely remove all diseased tissue within the tooth and seal it with a special filling to prevent re-infection. To access the diseased pulp, we first drill an access hole, usually in the biting surface of a back tooth or the back of a front tooth. We then use specialized instruments to remove the infected tissue and flush out the space with antibacterial solutions.
We then insert a filling called gutta percha into the empty pulp chamber and root canals, seal off the filling with adhesive cement, and close the access hole with filling. These fillings and sealants prevent bacteria from reentering the tooth. For added protection against infection and fracturing, we also recommend placing a full-coverage dental crown. This also enhances the appearance of the tooth, which must be modified during the root canal procedure.
The end result: your once endangered tooth has been preserved for hopefully many years to come. So if we recommend you undergo a root canal treatment, don't wait — the tooth you save may be your own.
