10 Root Canal Myths That Keep Davidson Patients Living With Tooth Pain

Few dental procedures carry as much undeserved baggage as the root canal. Mention those two words, and most people grimace—even if they’ve never actually had one. Decades of outdated jokes and exaggerated horror stories have turned this common, pain-relieving treatment into something many patients dread far more than they should.

At Smiles By Seese in Davidson, Dr. Brian Seese has spent over 20 years helping patients understand the truth about root canal therapy. After earning his Doctor of Dental Medicine degree from the University of Florida College of Dentistry, Dr. Seese has performed countless root canals for families throughout Davidson, Cornelius, Mooresville, and the greater Lake Norman region—and the feedback is consistently the same: “That was nothing like what I expected.”

If you’ve been putting off dental care because you’re worried a root canal might be in your future, it’s time to separate fact from fiction. Here are ten persistent myths about root canal therapy—and the reality that might surprise you.

Myth #1: Root Canals Are Extremely Painful

This is the big one—the myth that keeps more patients suffering with infected teeth than any other misconception. The reality? Root canals don’t cause pain. They relieve it.

The tooth infection that makes a root canal necessary is what causes agony. The procedure itself is performed under local anesthesia, meaning you shouldn’t feel anything more than mild pressure. Most patients describe the experience as similar to getting a filling—perhaps a bit longer, but certainly not the torture session popular culture has led them to expect.

In fact, a study published in the Journal of Endodontics found that patients who had root canals were six times more likely to describe the experience as “painless” compared to those who had teeth extracted.

Myth #2: It’s Better to Just Pull the Tooth

When facing an infected tooth, some patients assume extraction is the simpler solution. Why save a damaged tooth when you can just remove it?

The answer comes down to long-term oral health. Your natural teeth are almost always preferable to any replacement. Extracting a tooth triggers a cascade of changes: neighboring teeth shift into the gap, your bite alignment changes, bone loss begins in the empty socket, and the opposing tooth may start to drift.

Replacing an extracted tooth with an implant or bridge costs significantly more than a root canal and crown—and still doesn’t give you back your natural tooth. When Dr. Seese can save a tooth with root canal therapy, that tooth can function normally for decades, often for the rest of your life.

Myth #3: Root Canals Require Multiple Lengthy Appointments

Years ago, root canal therapy often required two or three visits spread over several weeks. Modern techniques and technology have dramatically shortened the process.

Today, most root canals at Smiles By Seese are completed in a single appointment lasting between 60 and 90 minutes, depending on the tooth’s complexity. Molars with multiple roots may take slightly longer than front teeth with single roots, but even these rarely require additional visits.

You’ll likely need to return for a crown to protect the treated tooth, but the root canal itself is typically a one-and-done procedure.

Myth #4: Root Canals Cause Illness and Disease

This myth traces back to poorly designed research from the early 1900s—research that has been thoroughly debunked by decades of modern science. The original “focal infection theory” suggested that bacteria trapped in root-canal-treated teeth could cause diseases throughout the body.

The American Association of Endodontists, the American Dental Association, and peer-reviewed research have all confirmed that root canal therapy is safe and does not cause systemic illness. The bacteria removed during a root canal are the problem—keeping an infected tooth untreated poses far greater health risks than treating it properly.

Myth #5: If Your Tooth Doesn’t Hurt, You Don’t Need a Root Canal

Pain is certainly a common indicator of tooth infection, but it’s not the only one—and sometimes it’s absent entirely. Teeth can die slowly, with the nerve losing sensation before obvious symptoms develop.

Signs that may indicate the need for root canal therapy include prolonged sensitivity to hot or cold that lingers after the stimulus is removed, darkening or discoloration of a tooth, swelling or tenderness in nearby gums, a persistent pimple-like bump on the gum, and pain when chewing or applying pressure.

Dr. Seese uses digital radiography and careful examination to identify infected teeth, sometimes catching problems before patients experience any symptoms at all. This is one of many reasons regular checkups matter—even when nothing seems wrong.

Myth #6: Root Canals Remove the Entire Tooth Root

The name “root canal” confuses some patients into thinking the procedure removes part of the tooth’s structure. In reality, a root canal removes infected tissue from inside the tooth while leaving the tooth itself intact.

Here’s what actually happens: Dr. Seese creates a small opening in the tooth’s crown, then carefully removes the infected pulp—the soft tissue containing nerves and blood vessels—from the interior chamber and root canals. These spaces are then cleaned, shaped, disinfected, and filled with a biocompatible material. The tooth’s root structure remains in place, anchored in your jawbone exactly as before.

Myth #7: Antibiotics Can Replace Root Canal Treatment

When patients learn they have an infected tooth, some ask whether antibiotics alone can solve the problem. Unfortunately, the answer is no—and understanding why helps explain what makes tooth infections unique.

Antibiotics travel through your bloodstream to reach infections throughout your body. But the infected pulp inside a tooth has lost its blood supply—that’s actually part of why it becomes infected. Without blood flow reaching the interior of the tooth, antibiotics simply can’t get to where they’re needed.

Antibiotics may temporarily reduce swelling and discomfort by addressing infection that has spread beyond the tooth into surrounding tissues. But they cannot eliminate the source of infection inside the tooth itself. Until that infected tissue is removed, the infection will return.

Myth #8: Root Canal–Treated Teeth Always Fail Eventually

Some patients hesitate to invest in root canal therapy because they’ve heard treated teeth inevitably fail. The statistics tell a different story: root canal therapy has a success rate exceeding 95% when performed properly and followed by appropriate restoration.

Treated teeth can last a lifetime with proper care. The keys to long-term success include protecting the tooth with a crown, maintaining good oral hygiene, attending regular dental checkups, and avoiding habits like chewing ice or using teeth as tools.

When root canal–treated teeth do fail, the cause is often inadequate restoration rather than the root canal itself. A tooth that’s been treated but not crowned is vulnerable to fracture, which is why Dr. Seese recommends crown placement following most root canal procedures.

Myth #9: You’ll Need to Take Days Off to Recover

Many patients expect significant downtime after a root canal, planning to take several days off work and clear their schedules. In most cases, this isn’t necessary.

The majority of patients return to normal activities—including work—the same day or the day after their procedure. You may experience some mild tenderness at the treatment site for a few days, but this is typically manageable with over-the-counter pain relievers like ibuprofen.

Because the procedure removes the infected nerve tissue causing your pain, many patients actually feel better after their root canal than they did before. The relief of finally addressing that persistent toothache outweighs any minor post-procedure discomfort.

Myth #10: All Root Canals Are the Same Complexity

Patients sometimes assume that if a friend or family member had an easy root canal experience, theirs will be identical—or vice versa. In reality, root canal complexity varies significantly based on the tooth involved.

Front teeth (incisors and canines) typically have single, straight root canals and are relatively straightforward to treat. Premolars usually have one or two roots with corresponding canals. Molars can have three or four roots with complex, curved canal systems that require more time and precision.

Dr. Seese evaluates each case individually using digital X-rays to understand the tooth’s anatomy before beginning treatment. This personalized approach ensures that whether your root canal is simple or complex, you receive the careful attention your specific situation requires.

When to Stop Worrying and Start Healing

Tooth infections don’t resolve on their own. They progress. What starts as occasional sensitivity can become constant pain, facial swelling, and eventually, tooth loss. Every week you spend worrying about a root canal is a week that infection has to worsen.

The truth is, patients who finally get the root canal they’ve been avoiding almost always say the same thing: “I wish I’d done this sooner.” The procedure itself is routine. The relief afterward is real. And keeping your natural tooth is worth the investment.
