Root Canal Treatment in Woodbury, MN
Root canal treatment relieves the pain of an infected tooth while giving you the best chance of keeping your natural tooth.
Treating an Infected Tooth
Root canal treatment has a reputation that doesn't quite match reality. Most patients who need one are already in pain from an infected or inflamed tooth — the procedure itself is aimed at relieving that pain, not causing it. This page walks through what a root canal actually treats, what the appointment involves, and answers the questions people search for most, including the one about whether it hurts.
If you're dealing with a persistent toothache, sensitivity to temperature that lingers, or a dentist has mentioned you might need a root canal, this should give you a realistic picture of what's ahead.
What Is a Root Canal?
Inside every tooth is a soft tissue called pulp, which contains nerves and blood vessels. When that pulp becomes infected or severely inflamed — usually from deep decay, a crack, or repeated dental work on the same tooth — it can cause significant pain and, left untreated, lead to an abscess. Root canal treatment removes the infected pulp, cleans and disinfects the inside of the tooth, and seals it, allowing you to keep the natural tooth instead of losing it.
The term 'root canal' technically refers to the space inside the tooth's root being treated, but it's commonly used to describe the whole procedure. It's performed by general dentists as well as endodontists, who specialize specifically in this type of treatment.
Who Might Need a Root Canal?
Root canal treatment is typically needed when the pulp inside a tooth becomes infected or irreversibly inflamed. This can result from a deep cavity that's reached the inner tooth, a crack that allows bacteria in, trauma to the tooth, or a tooth that's had multiple previous procedures.
Some patients have no obvious symptoms and find out they need treatment through an X-ray at a routine visit; others are in significant pain by the time they seek care. Either way, a dentist can confirm the diagnosis with an exam and imaging.
Signs You May Need a Root Canal
Common signs of an infected or inflamed tooth include:
- Persistent or severe tooth pain, especially when biting or chewing
- Lingering sensitivity to hot or cold that doesn't go away quickly
- Swelling or tenderness in the gums near a specific tooth
- A small, pimple-like bump on the gums
- Darkening of a tooth
- Pain that wakes you up at night
What to Expect During Root Canal Treatment
Root canal treatment is typically completed in one or two visits under local anesthetic:
- 1
Diagnosis and numbing
The dentist confirms the diagnosis with an exam and X-ray, then numbs the area thoroughly before starting.
- 2
Accessing the tooth
A small opening is made in the top of the tooth to reach the infected pulp.
- 3
Removing the infected tissue
The infected or inflamed pulp is carefully removed, and the inside of the tooth is cleaned and disinfected.
- 4
Sealing the tooth
The cleaned space is filled with a biocompatible material and sealed to prevent reinfection.
- 5
Restoring the tooth
Most teeth need a crown afterward to restore strength, since a root canal-treated tooth can become more brittle over time.
Why Save the Tooth?
Root canal treatment offers a real alternative to losing the tooth entirely:
- Relieves the pain caused by an infected or inflamed tooth
- Removes the source of infection, reducing the risk it spreads further
- Preserves your natural tooth and bite, which generally functions better than a replacement
- Avoids the additional cost and time associated with extraction and replacement
- Success rates are generally high when followed by an appropriate restoration like a crown
Cost and Insurance for Root Canal Treatment
Root canal cost varies based on which tooth is involved (molars are generally more complex than front teeth), whether a specialist is needed, and whether a crown is required afterward. Many dental insurance plans provide partial coverage for root canal treatment as a major or basic procedure, depending on the plan.
The participating provider you're connected with can give you a clearer estimate after evaluating the specific tooth involved.
Root Canal vs. Extraction
When a tooth is infected, there are generally two paths forward:
Root canal treatment
Removes the infection while preserving the natural tooth — usually the preferred option when the tooth can be saved.
Extraction
Removes the tooth entirely, which may be necessary if the tooth is too damaged to save. See our tooth extraction and dental implants pages for what comes next.
Frequently Asked Questions
Does a root canal hurt?
The procedure itself is performed under local anesthetic and is generally no more uncomfortable than getting a filling. Most of the pain people associate with root canals actually comes from the infection beforehand — the treatment is what relieves it.
How do I know if I need a root canal?
Signs include persistent tooth pain, lingering sensitivity to hot or cold, swelling near a tooth, or a small bump on the gums. A dentist can confirm with an exam and X-ray.
What are the signs of a tooth infection?
Common signs include throbbing pain, sensitivity that lingers after hot or cold exposure, swelling, a bad taste, and sometimes a low fever. Seek prompt dental care if you notice these symptoms.
How long does a root canal take?
Most root canal treatments take one to two visits, generally 60 to 90 minutes each, depending on the tooth and its complexity.
What's the alternative to a root canal?
The main alternative is extracting the tooth entirely, typically followed by a replacement option like a dental implant, bridge, or partial denture.
Do I need a crown after a root canal?
Often, yes, particularly for back teeth that handle significant chewing force. A root canal-treated tooth can become more brittle, and a crown helps protect it long-term.
How much does a root canal cost?
Cost depends on which tooth is treated and whether a specialist or crown is needed. The provider you're connected with can give you a specific estimate after an evaluation.
Can an untreated tooth infection become dangerous?
Yes — an untreated dental infection can spread to surrounding tissue and, in rare cases, become a serious medical concern. Seek prompt care for signs of infection, and seek emergency care for facial swelling that's severe or spreading quickly.
