The Top 10 Root Canal Myths Debunked

The Top 10 Root Canal Myths Debunked

7th April 2025

If someone mentions a “root canal,” what’s your first reaction? If it’s a grimace, you’re not alone. Root canal treatment is one of the most misunderstood procedures in dentistry, and it’s often the subject of outdated ideas and unnecessary fear.

We want to set the record straight. Root canal treatment has come a long way in recent years. Thanks to modern techniques and gentle care, the procedure is safe, comfortable, and incredibly effective at saving teeth.

In this article, we’ll bust ten of the most common root canal myths and explain what you can expect to feel informed, reassured, and confident in your dental care.

Top Ten Common Myths About Root Canal Care

Myth 1: Root canals are extremely painful

This is one of the biggest misconceptions out there. In reality, a root canal doesn’t cause pain—it relieves it.

Modern root canal treatment uses a local anaesthetic, meaning the area is completely numb during the procedure. Most patients say it feels no different from having a standard filling.

If you’re already in pain due to an infected or damaged tooth, root canal treatment can offer fast relief and stop the problem from getting worse.

Myth 2: It’s better just to remove the tooth

While tooth extraction may seem like a quick fix, keeping your natural teeth whenever possible is always the best option.

Root canal treatment allows us to save and restore the natural tooth structure, helping you maintain proper chewing function, jawbone support, and a natural-looking smile.

A missing tooth may need to be replaced with a bridge, denture, or implant, which can involve more time and expense in the long run.

Myth 3: Root canal treatment doesn’t last

With proper care, a tooth that’s been treated with a root canal can last many years—even a lifetime.

Once the infection is removed and the tooth is restored (often with a crown for added strength), it functions just like any other tooth. Good oral hygiene, regular check-ups, and routine cleaning all help ensure long-term success.

Myth 4: Root canals cause illness

This myth dates back to flawed research from the early 20th century, which has since been widely discredited.

No scientific evidence supports the claim that root canal treatment causes health problems elsewhere in the body. In fact, leaving an infected tooth untreated is far more likely to affect your overall health.

Modern root canal treatment is safe, regulated, and highly effective at eliminating infection.

Myth 5: The treatment takes multiple long appointments

While complex cases may require two or more visits, many root canal treatments can now be completed in just one or two appointments.

Thanks to digital imaging, modern instruments, and improved materials, the process is far more efficient than it used to be. We’ll always explain your treatment plan clearly and make it as convenient as possible.

Myth 6: You’ll be in pain for days afterwards

It’s normal to feel some mild tenderness for a few days after the procedure, especially when chewing. But this discomfort is usually short-lived and can be managed with over-the-counter pain relief.

In most cases, any pain or pressure you felt before the root canal is significantly reduced within a day or two after treatment.

Myth 7: Only people with severe tooth pain need root canals

Toothache is a common sign of infection, but it’s not the only one. Sometimes, infected teeth cause no pain at all, especially in the early stages.

Other warning signs might include:

• Sensitivity to hot or cold
• Swelling or tenderness in the gums
• Discolouration of the tooth
• A small bump on the gum (abscess)

That’s why it’s so important to have regular dental check-ups; we can spot problems early and treat them before they get worse.

Myth 8: Root canal treatment weakens your tooth

It’s true that a tooth with a root canal no longer has living tissue inside. But the tooth itself is preserved and protected with a filling or crown, which helps restore its strength and function.

In fact, a crown placed after a root canal can reinforce the tooth and protect it from future damage or fracture.

Myth 9: You can’t have a root canal if you’re nervous or anxious

We completely understand that some people feel nervous about dental treatment—and that’s OK. We take a gentle, understanding approach and offer solutions to help you feel calm and comfortable.

This includes:

• Clear explanations so you know what to expect
• Breaks during treatment if needed
• Sedation options for patients with severe anxiety

You’re always in control. We’ll go at your pace and make sure you feel supported throughout the process.

Myth 10: Root canals are only for older people

Tooth infections can happen to anyone, whether due to deep decay, cracks, trauma, or old fillings. That’s why people of all ages may require root canal treatment.

We’ve treated patients in their teens, twenties, and well beyond. No matter your age, the goal is the same: to save your natural tooth and eliminate pain or infection safely.

What Actually Happens During a Root Canal?

Here’s a quick overview of what the process typically involves:

1. Using anaesthetic so you feel no discomfort
2. Removing the infected pulp (the soft tissue inside your tooth)
3. Cleaning and disinfecting the inner space of the tooth
4. Filling the space with a special material
5. Sealing the tooth, often with a crown to restore strength and function

The whole process is carried out with precision, care, and the latest techniques to ensure excellent results.
