Bad news at your last dental visit: You have a decayed tooth. And not just in the enamel—the decay has invaded the tooth's inner pulp and the resulting infection is threatening the supporting bone structure.
You're thinking that tooth is toast. Then comes the good news: your dentist believes the tooth can be rescued with a root canal treatment.
But then you begin thinking about how often Uncle Sid says he'd rather undergo a colonoscopy than have a root canal. Is the procedure really as painful and uncomfortable as popular culture says it is? What is a root canal really like?
First step: Things go numb. Uncle Sid is wrong: A root canal treatment is painless because your dentist will first make sure the entire area involving the tooth is anesthetized. This does involve injecting the local anesthetic deep within the tissues, but you won't even feel the needle prick thanks to topical anesthesia applied to the surface gums.
Second step: Drilling deep. After applying a protective dam to isolate the infected tooth from its neighbors, your dentist will drill a small access hole through the enamel and dentin to reach the pulp and root canals. If it's one of the larger back teeth, the access hole is usually drilled in the tooth's biting surface; in a front tooth, the hole is usually located on the tongue side.
Third Step: Removing diseased tissue. Using special instruments, your dentist will remove the diseased tissue in the pulp and root canals, essentially stopping the infection and any tooth pain you've been experiencing. The empty pulp chamber and canals are often then disinfected with a special antibacterial solution.
Fourth Step: Protecting the tooth. After some shaping, the pulp chamber and root canals are filled with a special filling to prevent further infection. The access hole is then filled and sealed to complete the procedure. At some point in the future, the tooth typically will need a crown to add support and further protection.
You may have some minor discomfort afterward, but this can usually be managed with a mild pain reliever like ibuprofen or acetaminophen. After a week or so, you'll be good as new—and so will your tooth.

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.
