What Is a Root Canal?

A root canal is a dental procedure used to treat infection or inflammation inside a tooth. When the soft tissue (called pulp) inside your tooth becomes infected due to deep decay, a crack, or trauma, a root canal helps remove the infection and save the natural tooth.

Rather than pulling the tooth, a root canal cleans it out, seals it, and restores its function, often with a crown.

Most Frequently Asked Questions About Root Canal

Below are some of the most frequently asked questions about root canal. 

  • Does a Root Canal Hurt?

This is probably the #1 question on everyone's mind—and thankfully, the answer is no.

With today's local anesthetics and advanced techniques, a root canal feels a lot like getting a filling. Most patients report relief from pain, not more pain, since the procedure removes the infected tissue that's causing discomfort.

You may feel a bit of soreness afterward, but it's usually mild and short-lived.

  • How Do I Know If I Need a Root Canal?

Here are some common signs that could mean your tooth needs attention:

  • Persistent toothache that doesn't go away
  • Sensitivity to hot or cold, especially if it lingers
  • Swollen or tender gums near one tooth
  • Darkening or discoloration of a tooth
  • Pimple-like bump on the gums (abscess)

If you're experiencing any of these, don't ignore them—a root canal might just save your tooth.

  • What Happens During a Root Canal Procedure?

While each case is unique, here's a general breakdown of what happens during a root canal:

  • Numbing the Area: A local anesthetic is used to make sure you're comfortable.
  • Opening the Tooth: Your dentist creates a small opening to access the infected pulp.
  • Removing the Infection: The infected or damaged tissue is removed from inside the tooth.
  • Cleaning the Canals: The inside of the tooth is thoroughly cleaned and shaped.
  • Filling and Sealing: The space is filled with a special material to prevent future infection.
  • Final Restoration: A crown or filling is placed to restore full function and appearance.

The whole thing usually takes one or two visits, and you can go back to normal activities soon after.

  • How Long Does a Root Canal Take?

Most root canals can be completed in 60 to 90 minutes, depending on the complexity of the tooth and how many canals need to be cleaned.

If it's a molar or a more complex case, it might take two visits—one for cleaning and one for sealing and restoration.

  • What Is Recovery Like After a Root Canal?

After the procedure, it's normal to feel a bit of tenderness or mild soreness for a few days, especially when chewing. This is your body's natural response to healing.

Most people manage just fine with over-the-counter pain medication, and you can return to work or school the next day.

Just stick to soft foods for a day or two, and avoid chewing on the treated tooth until it's fully restored with a crown or filling.

  • Will I Need a Crown After a Root Canal?

In most cases, yes. After a root canal, the tooth is no longer living, which makes it more brittle over time. A crown helps protect the tooth structure, restore full chewing power, and improve appearance.

Your dentist will determine if a crown is needed based on the location and condition of the tooth.

  • How Long Does a Root Canal Last?

When done properly and cared for well, a root canal can last a lifetime.

Good oral hygiene, brushing, flossing, and regular dental checkups—goes a long way. Crowning the tooth also adds to its longevity by protecting it from fractures.

  • Are There Alternatives to a Root Canal?

The main alternative to a root canal is tooth extraction, which may be followed by a dental implant, bridge, or partial denture.

However, nothing replaces your natural tooth as effectively as keeping it. Root canals are generally more cost-effective and less invasive in the long run than having a tooth pulled and replaced.

  • Is a Root Canal Expensive?

The cost of a root canal depends on the tooth being treated and your location, but it generally ranges from $700 to $1,500. Molars usually cost more because they have more roots.

Many insurance plans cover part of the cost, especially if it's considered a medically necessary procedure.

Compared to extraction and implant replacement—which can run $3,000–$5,000 or more—a root canal is often the more affordable option.

  • Can I Drive Home After a Root Canal?

Yes—in most cases, you can drive yourself home. If only local anesthesia is used (which is typical), you'll be alert and fine to resume normal activities.

However, if sedation or general anesthesia is involved (less common), you'll need someone to drive you home.

Bonus: Root Canal Myths Debunked

  • “Root canals are extremely painful.”

    Not anymore! With modern techniques, they're about as comfortable as getting a filling.
  • “It's better to pull the tooth.”

    Saving your natural tooth is usually better for your long-term oral health and function.
  • “The tooth will eventually fall out anyway.”

    Not true. With proper care, a root canal-treated tooth can last for decades.

Final Thoughts 

Root canals may have a bad reputation, but the reality is far less scary. They're one of the most effective ways to save a natural tooth, stop pain, and prevent future dental issues.

If you're experiencing symptoms—or your dentist has recommended one—don't panic. Ask questions, get the facts, and trust that you're taking a smart step toward a healthier smile.
