Few dental procedures have a worse reputation than the root canal. Mention those two words and most people immediately picture outdated dental chairs, excruciating pain, and hours of misery. But here’s the truth: modern root canal therapy bears almost no resemblance to the horror stories you’ve heard. At Kennesaw Mountain Dental Associates, Dr. Hamir Contractor and our team perform comfortable, effective root canal treatments that save teeth and eliminate pain—not cause it.
If you’ve been avoiding the dentist because you suspect you might need a root canal, or if you’re currently experiencing tooth pain but dreading the treatment, it’s time to separate fact from fiction.
Myth #1: Root Canals Are Extremely Painful
This is the granddaddy of all root canal myths, and it couldn’t be further from the truth. The reality? Root canal therapy relieves pain rather than causes it.
The pain people associate with root canals actually comes from the infected tooth itself. When the pulp inside your tooth becomes infected or inflamed, the pressure and bacterial activity create intense, often throbbing pain. The root canal procedure removes this infected tissue, eliminating the source of your discomfort.
Modern anesthesia techniques ensure you won’t feel the procedure. Dr. Contractor takes time to ensure you’re completely numb before beginning any work. Most patients report that the experience feels similar to getting a filling—you’ll feel some pressure and vibration, but no pain.
In fact, a study by the American Association of Endodontists found that patients who have experienced root canal treatment are six times more likely to describe it as painless than patients who have never had one. The anticipation is almost always worse than the reality.
Myth #2: It’s Better to Just Pull the Tooth
When faced with the prospect of root canal treatment, some patients ask if extraction would be simpler. While pulling a tooth might seem like a quicker fix, it actually creates a cascade of problems that far outweigh the minor inconvenience of root canal therapy.
Every tooth in your mouth serves a purpose. When you lose one, the neighboring teeth begin to shift into the empty space, potentially causing bite problems and misalignment. The bone that once supported the missing tooth starts to deteriorate. Your ability to chew properly becomes compromised. And replacing the missing tooth with an implant or bridge typically costs significantly more than saving the natural tooth with a root canal.
Your natural teeth are designed to last a lifetime with proper care. A tooth that has undergone successful root canal treatment, followed by appropriate restoration like a crown, can function normally for decades. Preservation should always be the goal when it’s achievable.
Myth #3: Root Canals Cause Illness
You may have encountered articles or social media posts claiming that root canals cause cancer, heart disease, or other systemic illnesses. These claims trace back to poorly designed research from nearly a century ago that has been thoroughly debunked by modern science.
The original “focal infection theory” from the 1920s suggested that bacteria trapped in root canal-treated teeth could cause disease elsewhere in the body. However, this theory was based on flawed methodology and has been rejected by the scientific and medical communities for decades.
Multiple peer-reviewed studies have found no valid scientific evidence linking root canal treatment to disease elsewhere in the body. The American Association of Endodontists, American Dental Association, and numerous other professional organizations confirm that root canal therapy is both safe and effective.
What actually poses a health risk? Leaving an infected tooth untreated. Dental infections can spread to surrounding tissues, the jawbone, and in severe cases, other parts of the body. Treating the infection through root canal therapy protects your overall health.
Myth #4: Root Canals Require Multiple Long Appointments
Years ago, root canal treatment often did require several lengthy visits. Today’s technology has transformed the procedure dramatically.
At Kennesaw Mountain Dental Associates, most root canals are completed in a single appointment lasting about 60 to 90 minutes. Advances in imaging, instrumentation, and techniques have made the process far more efficient than in previous decades.
Digital x-rays provide instant, detailed images that help Dr. Contractor plan and execute treatment precisely. Modern rotary instruments clean and shape the root canals more quickly and thoroughly than older hand files. Better filling materials create more reliable seals. The result is faster treatment with better outcomes.
Some complex cases involving multiple canals or unusual anatomy may require a second visit, but single-appointment root canals have become the norm rather than the exception.
Myth #5: If Your Tooth Doesn’t Hurt, You Don’t Need a Root Canal
Pain is certainly one indicator that something is wrong inside a tooth, but the absence of pain doesn’t mean all is well. In some cases, the nerve inside an infected tooth dies, eliminating pain signals even though the infection continues.
A tooth that once caused significant pain but suddenly stops hurting shouldn’t be ignored. This could indicate that the nerve has died—but the infection remains, silently damaging surrounding bone and tissue.
Other signs that you might need root canal treatment include prolonged sensitivity to hot or cold temperatures that lingers after the stimulus is removed, darkening or discoloration of a tooth, swelling or tenderness in nearby gums, and a persistent pimple-like bump on the gums near a specific tooth.
Regular dental checkups allow your dentist to identify problems before they become painful emergencies. X-rays can reveal infection at the root tip even when you feel fine. This is one of many reasons why those twice-yearly visits matter so much.
What Actually Happens During a Root Canal
Understanding the procedure often helps alleviate anxiety. Here’s what you can expect when you visit Kennesaw Mountain Dental Associates for root canal therapy:
First, Dr. Contractor will thoroughly numb the area around the affected tooth. You’ll feel pressure during the injection, but the area will be completely anesthetized before any treatment begins.
Next, a small protective sheet called a dental dam is placed around the tooth to keep it clean and dry during the procedure. A small opening is made in the crown of the tooth to access the pulp chamber.
Using specialized instruments, Dr. Contractor removes the infected or inflamed pulp tissue from inside the tooth and root canals. The canals are then carefully cleaned, shaped, and disinfected to remove all bacteria and debris.
Once the canals are thoroughly cleaned, they’re filled with a biocompatible material called gutta-percha, which seals the space and prevents future infection. A temporary filling closes the opening.
In most cases, a crown is recommended to protect and strengthen the tooth after root canal treatment. This is typically placed at a follow-up appointment once the tooth has healed.
When to Seek Treatment
Tooth pain shouldn’t be ignored, and delaying treatment for an infected tooth only makes matters worse. The infection can spread, the tooth may become unsaveable, and your overall health could be compromised.
If you’re experiencing any of the following symptoms, contact Kennesaw Mountain Dental Associates for an evaluation:
- Severe Toothache: Pain that throbs, worsens when lying down, or disrupts sleep
- Prolonged Sensitivity: Lingering discomfort after exposure to hot or cold
- Swelling: Puffiness in your face, jaw, or gums near a specific tooth
- Darkening: A tooth that appears darker than its neighbors
- Gum Issues: Tenderness, swelling, or a recurring pimple near a tooth
Early intervention often means simpler treatment and better outcomes. Don’t let outdated myths prevent you from getting the care you need.
