"Root canal" has become dental shorthand for the worst possible experience, a punchline before it's even a procedure. That reputation is almost entirely inherited from decades-old dentistry and Hollywood exaggeration. Modern root canal treatment, done with contemporary anesthesia and technique, is routinely described by patients as no more uncomfortable than getting a filling.
Myth: Root Canals Are Extremely Painful
This is the big one, and it's the most outdated. The pain people associate with root canals almost always comes from the infection that made the root canal necessary in the first place, not the procedure itself. Modern anesthesia numbs the area thoroughly, and most patients report the treatment itself feels comparable to having a cavity filled. The procedure is what relieves the pain, not what causes it.
Myth: Extraction Is a Better Option Than a Root Canal
It's tempting to think pulling a problem tooth is simpler than saving it, but extraction usually creates more problems than it solves. Losing a tooth can lead to shifting of neighboring teeth, bite changes, and eventually the need for an implant or bridge, which is typically more expensive and time-consuming than the root canal would have been. Saving your natural tooth is almost always the better long-term outcome.
Myth: Root Canals Don't Really Work Long-Term
According to the American Association of Endodontists, root canal treatment has a success rate that often exceeds 90%, and a properly restored, well-maintained root canal-treated tooth can function for decades, often for life. Long-term success depends heavily on getting a permanent restoration (usually a crown) placed promptly after treatment and keeping up with regular oral hygiene.
What a Root Canal Actually Involves
The procedure removes infected or inflamed pulp (the tooth's inner soft tissue) from the tooth's interior, cleans and disinfects the space, then fills and seals it. Afterward, the tooth is typically restored with a crown, since a root canal-treated tooth becomes more brittle without the extra reinforcement. Most root canals are completed in a single visit, sometimes two for more complex cases.
