As an endodontist in Torrance, I hear misconceptions about root canal treatment almost daily. These myths often cause patients unnecessary anxiety or lead them to delay treatment—which can result in losing a tooth that could have been saved.
Let’s separate fact from fiction.
Myth #1: “Root Canals Are Extremely Painful”
Myth: Root canals are one of the most painful dental procedures you can have.
Reality: Root canal treatment doesn't cause pain — it relieves it. The pain patients associate with root canals actually comes from the infection that makes the procedure necessary. Modern anesthesia techniques, advanced instruments, and experienced specialists make the actual treatment virtually painless.
In fact, studies consistently show that patients who’ve had a root canal rate the experience as no more uncomfortable than getting a filling. Many of my patients tell me, “That’s it? I was so worried for nothing!”
What’s changed: Today’s endodontists use:
- More effective local anesthetics
- Rotary instruments that work faster and gentler
- Microscopes for precision
- Advanced techniques for even the most challenging cases
Myth #2: “It’s Better to Just Pull the Tooth”
Myth: Extraction is simpler and cheaper — just pull the tooth and be done with it.
Reality: Saving your natural tooth is almost always the better choice — both for your health and your wallet. Your natural teeth are designed to work together, and losing one creates a cascade of problems.
When you lose a tooth:
- Adjacent teeth can shift, affecting your bite
- The jawbone beneath the extracted tooth begins to deteriorate
- Chewing efficiency decreases
- You’ll need a replacement (implant, bridge, or partial denture), which costs more and requires additional procedures
A root canal followed by a crown preserves your natural tooth structure. With proper care, a treated tooth can last a lifetime.
The cost reality: A root canal plus crown typically costs less than an extraction plus implant, and you keep your natural tooth.
Myth #3: “Root Canals Cause Illness”
Myth: Root canals trap bacteria and cause disease elsewhere in the body.
Reality: This myth originated from poorly designed research from the 1920s — over 100 years ago. It has been thoroughly debunked by decades of modern scientific evidence. The American Association of Endodontists, the American Dental Association, and numerous peer-reviewed studies confirm that root canal treatment is safe.
There is no valid scientific evidence linking root canals to disease elsewhere in the body.
The real danger: Leaving an infected tooth untreated can lead to serious health problems. Dental infections can spread, causing facial swelling, bone loss, and in rare cases, life-threatening complications.
Myth #4: “If the Tooth Doesn’t Hurt, It Doesn’t Need Treatment”
Myth: If your tooth isn't hurting, there's nothing wrong with it.
Reality: Teeth that need root canals don't always hurt — especially if the nerve has already died. A tooth can have a serious infection with no pain at all.
Signs you might need treatment even without pain:
- Darkening or discoloration of a tooth
- A small pimple on your gums that comes and goes
- Prolonged sensitivity to hot or cold
- Tenderness when chewing or touching the tooth
- Visible damage or deep decay on X-rays
Regular dental checkups are essential because your dentist can identify problems before they become painful emergencies.
Myth #5: “Root Canals Require Multiple Long Appointments”
Myth: Root canals take multiple visits and hours in the dental chair.
Reality: Most root canals are completed in a single visit lasting 60–90 minutes. Thanks to modern technology and techniques, what once required multiple appointments can now typically be done in one.
Advanced tools I use include:
- CBCT 3D imaging: Allows me to see your tooth anatomy in complete detail before we begin
- Rotary instruments: Clean canals faster and more thoroughly
- GentleWave technology: Uses advanced fluid dynamics to disinfect the entire root canal system
Some complex cases (like teeth with unusual anatomy or significant infection) may benefit from two visits, but this is the exception rather than the rule.
What Modern Root Canal Treatment Is Really Like
Here’s what you can actually expect at our Torrance office:
Consultation and Imaging
We'll discuss your symptoms, take detailed images, and explain exactly what's happening with your tooth.
Numbing
You'll receive thorough anesthesia. We don't start until you're completely comfortable.
Treatment
Using microscopes and specialized instruments, I'll remove the infected tissue, clean the canals, and seal the tooth. Most patients catch up on podcasts or close their eyes and relax.
Aftercare
You'll leave with clear instructions. Most patients take over-the-counter pain medication for a day or two and return to normal activities immediately.
Follow-Up
Your referring dentist will place a crown to protect and restore your tooth.
The Bottom Line
Root canal treatment has an undeserved reputation. In reality, it’s a routine procedure that saves millions of teeth every year with a success rate over 95%.
If you’ve been putting off needed treatment because of fear or misinformation, I encourage you to schedule a consultation. I’m happy to answer any questions and show you how modern endodontics has evolved.
