Root Canal Myths vs. Facts: What Every Patient Should Know

If you’ve ever heard the words “you need a root canal” and felt your stomach drop, you’re not alone. Root canals are one of the most misunderstood procedures in all of dentistry — surrounded by decades of myths, outdated horror stories, and unnecessary fear. The truth? Modern root canal treatment is comfortable, routine, and often the best way to relieve pain and save a tooth you’d otherwise lose.

At Long Island Endodontics in Woodmere, NY, we specialize exclusively in root canal therapy and endodontic care. We want to set the record straight — because an informed patient is a calm patient.

Myth #1: “Root Canals Are Extremely Painful”

This is the most persistent myth in dentistry — and the most outdated.

The fact: Root canal treatment doesn’t cause pain. It relieves it. The discomfort most people associate with a root canal is the infection or dental abscess that made the procedure necessary in the first place. The procedure itself is performed under local anesthesia, and the vast majority of patients report that it feels no different from having a routine filling placed.

A landmark survey by the American Association of Endodontists found that patients who have had a root canal are six times more likely to describe it as painless than patients who have never had one.

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

When a tooth is badly infected or damaged, extraction can seem like the simpler option. Many patients ask: why not just take it out?

The fact: Saving your natural tooth is almost always the better long-term choice. Once a tooth is removed, the surrounding bone begins to shrink, neighboring teeth can shift, and you’ll need a bridge or implant to restore function — both of which are more expensive and time-consuming than a root canal.

Endodontists train for years beyond dental school specifically to preserve natural teeth. A root canal followed by a crown can keep your tooth functional and healthy for the rest of your life.

Myth #3: “Root Canals Cause Illness”

You may have come across claims online suggesting that root canals are linked to cancer, heart disease, or systemic illness. This idea traces back to research from the early 1900s that has long since been thoroughly debunked.

The fact: Modern research does not support any connection between root canal treatment and systemic disease. The American Dental Association, the American Association of Endodontists, and major medical institutions all confirm that root canal therapy is a safe, evidence-based procedure. Choosing not to treat an infected tooth, on the other hand, poses genuine risks — including the spread of infection to the jaw, neck, or beyond.

Myth #4: “If It Doesn’t Hurt, There’s No Problem”

Many patients delay seeking care because a tooth that looks or feels “fine” doesn’t seem urgent.

The fact: Dental infections are not always painful. A tooth with a dying or already-dead nerve may show no pain at all, even while harboring a significant infection at the root tip. Signs like tooth discoloration, a pimple-like bump on the gums, or sensitivity to pressure can all indicate a problem even in the absence of acute pain.

If your dentist or endodontist recommends a root canal, it’s because clinical and radiographic evidence — not just pain level — points to the need for treatment.

Myth #5: “Root Canals Require Many Appointments”

Patients sometimes put off treatment because they assume it will mean multiple long visits.

The fact: The majority of root canals can be completed in one or two appointments. Modern rotary instruments, digital imaging, and cone beam CT scanning (CBCT) allow endodontists to work with exceptional precision and efficiency. At Long Island Endodontics, we work to make your experience as streamlined and comfortable as possible.

Myth #6: “All Dentists Perform Root Canals the Same Way”

You might wonder: can’t my regular dentist just do this?

The fact: While general dentists are trained to perform root canals, an endodontist is a specialist who has completed two to three additional years of residency training focused exclusively on diagnosing tooth pain and treating the inner tooth. Endodontists handle the most complex cases — curved roots, calcified canals, prior treatment failures, and intricate internal anatomy.

Choosing an endodontist for your root canal is like choosing a cardiologist for a heart procedure. Same underlying system — but a much deeper level of expertise.

When Should You See an Endodontist?

Talk to your dentist about a referral if you’re experiencing any of the following:

• Prolonged sensitivity to heat or cold that lingers after the source is removed

• Spontaneous, throbbing toothache — especially at night

• Swelling or tenderness in the gums near a tooth

• Darkening or discoloration of a tooth

• A recurring pimple or bump on the gumline

• Deep decay or a cracked tooth that has reached the nerve

• Trauma to a tooth — even if it looks intact

  
  

These symptoms don’t always mean a root canal is needed, but they do warrant a professional evaluation. The sooner an infected or damaged tooth is assessed, the more likely it can be saved.

The Bottom Line

Root canals have a bad reputation they simply don’t deserve. Modern endodontic treatment is safe, effective, and in most cases — comfortable. Millions of teeth are saved every year through this procedure, and the alternative (tooth loss) carries its own costs and complications.

If you’ve been told you may need a root canal, or if you’re experiencing tooth pain and want answers, we’re here to help.
