A Beautiful Practice For All Your Dental Needs

Treat the Problem Inside the Tooth

When infection or inflammation reaches the inner part of a tooth, simply treating the surface won't solve the problem. Root canal treatment removes the affected tissue, cleans the inside of the tooth, and seals the canals to help prevent the infection from returning.

At Duluth Dental Care, we evaluate the tooth and its surrounding structures before recommending treatment. If a root canal is appropriate, we'll explain what is happening and what you can expect throughout the process.

When Might You Need a Root Canal?

A tooth may need endodontic treatment when its inner tissue becomes infected or severely inflamed. Some infected teeth cause little or no discomfort, so the absence of pain doesn't necessarily mean the tooth is healthy.

Common warning signs include:

Persistent or worsening tooth pain
Sensitivity to hot or cold that lingers
Pain when biting or chewing
Swelling near the tooth
A recurring abscess or infection
A tooth that has been significantly damaged or injured

Can a Previously Treated Tooth Need Another Root Canal?

Understanding Root Canal Retreatment

Sometimes a tooth doesn't heal as expected after its initial root canal or develops a new infection months or years later. In these situations, root canal retreatment may be an option for preserving the tooth.

Treatment can fail or a new infection can develop for several reasons, including untreated or complex canals, leakage around a restoration, new decay, or damage to the tooth or restoration.

During retreatment, the existing root canal material is removed so the canals can be cleaned, examined, and sealed again. A microscope may be used when additional canals or complicated anatomy need closer inspection.

After retreatment, the tooth will generally need a permanent restoration, such as a crown, to protect it from further damage.

The Goal: Keep Your Natural Tooth When Possible

A root canal isn't about replacing a tooth—it's about treating the infection inside it while preserving as much of the natural tooth as possible. If the tooth can be predictably treated and restored, keeping it may help maintain your natural bite and avoid the need to replace the tooth. Your dentist will evaluate factors such as the amount of remaining tooth structure, cracks or fractures, infection, and the condition of previous dental work when determining whether treatment is appropriate.

Tooth pain doesn't always tell you exactly what's wrong. A proper examination can determine whether the problem involves the nerve, surrounding tissues, a previous restoration, or something else entirely.

Frequently Asked Questions

Is a root canal painful?

Modern dental techniques and local anesthesia are used to keep you comfortable during treatment. You may experience some tenderness afterward, particularly if the tooth was already inflamed or infected.

How do I know if I need a root canal?

Persistent tooth pain, lingering temperature sensitivity, pain when chewing, swelling, or a recurring infection can be signs that the inner part of a tooth is affected. An examination is needed to determine the cause.

Can a tooth that already had a root canal become infected again?

Yes. A previously treated tooth can develop a new infection or fail to heal completely. New decay, leakage around a restoration, untreated canal anatomy, or damage to the tooth can contribute to the problem.

What is root canal retreatment?

Root canal retreatment involves reopening a previously treated tooth, removing the existing canal filling material, cleaning and examining the canals, and then filling and sealing them again.

Does every failed root canal require an extraction?

No. Depending on the condition of the tooth, retreatment or endodontic surgery may provide an alternative to extraction. The appropriate option depends on the individual tooth.

Why might I need a crown after a root canal?

A tooth that has undergone root canal treatment may require additional protection from biting forces. A crown or another permanent restoration can help restore the tooth's function and protect the remaining structure.

Can I need a root canal even if my tooth doesn't hurt?

Yes. Some infections or changes inside a tooth may not cause noticeable symptoms. Dental examination and imaging can help identify problems that aren't obvious to you.
