Root Canal Myths Debunked: 7 Things Patients Get Wrong

If the words "root canal" make you tense up, you're not alone — and you're also probably working from outdated information. Root canal treatment has one of the worst reputations in dentistry, but most of what people believe about it hasn't been true for decades. At Equinox Dental in Monroe, NC, we perform root canals and root canal re-treatments regularly for patients throughout Union County and South Mecklenburg County, and we hear the same myths over and over. Here are seven of the biggest, and what's actually true.

Myth 1: Root Canals Are Extremely Painful

This is the myth we hear the most, and it's the one modern dentistry has done the most to disprove. The pain patients associate with a root canal almost always comes from the infected or inflamed tooth before treatment — not from the procedure itself. With modern local anesthesia, most patients feel pressure and vibration during treatment, not pain. In fact, patients who have actually had a root canal are far more likely than those who haven't to describe it as comfortable. The procedure is designed to relieve pain, not create it.

Myth 2: It's Better to Just Pull the Tooth

Extraction can seem like the simpler option, but saving your natural tooth almost always serves you better long-term. A missing tooth changes how you chew, can shift neighboring teeth out of position, and often requires a bridge or implant later to restore function — additional treatment that a root canal avoids entirely. When a tooth can be saved, we'll walk you through both options honestly so you can weigh the real tradeoffs for your situation.

Myth 3: Root Canals Cause Illness Elsewhere in the Body

This myth traces back to research from nearly a century ago that has since been thoroughly discredited. There is no credible modern evidence linking root canal treatment to heart disease, arthritis, or other systemic conditions. Root canal treatment removes infected tissue from inside the tooth and seals it — it doesn't introduce new health risks.

Myth 4: A Root-Canal-Treated Tooth Won't Last

With a proper crown or restoration afterward and normal care, a root canal-treated tooth can last the rest of your life. These teeth do become slightly more brittle over time, which is exactly why we typically recommend a crown to protect it — but "won't last" simply isn't accurate for most patients. Regular checkups and good home care matter just as much for a treated tooth as they do for any other tooth in your mouth.

Myth 5: If It Doesn't Hurt, You Don't Need One

Not every infected tooth announces itself with pain. Nerve damage or infection inside a tooth can progress quietly, sometimes only showing up on an X-ray during a routine exam. That's part of why regular checkups matter — catching a problem before it becomes painful usually means a simpler, more predictable treatment.

Myth 6: One Root Canal Attempt Is Your Only Shot

If a treated tooth becomes reinfected or doesn't heal as expected, it isn't automatically headed for extraction. Root canal re-treatment or an apicoectomy — a minor surgical procedure that addresses infection at the root tip — can often save the tooth a second time. We perform both procedures in-house, so if your first root canal (whether done here or elsewhere) needs a second look, you don't need a referral to get it addressed or a separate trip to an unfamiliar office.

Myth 7: Recovery Takes Weeks

For most patients, recovery is a matter of days, not weeks. Mild soreness around the treated tooth is normal for a couple of days and typically responds well to over-the-counter pain relief. Most people are back to their normal routine, including work or school, the next day.

The Bottom Line

Root canal treatment has come a long way from its reputation, and most of what makes it sound frightening simply isn't accurate anymore. If you're dealing with tooth pain, sensitivity, or a dentist has flagged a tooth on an X-ray, don't let outdated myths delay getting it looked at — the earlier a problem is caught, the more straightforward treatment tends to be.
