Root Canal Therapy

What is a root canal?

A root canal is a simple treatment that saves a tooth when its pulp has become infected. The pulp is at the center of your tooth and is a collection of blood vessels, tissues, and nerves that help to build the surrounding tooth. Infection of the pulp can be caused by trauma to the tooth, deep decay, cracks and chips, or repeated dental procedures. Various symptoms of the infection may include visible injury or swelling of the tooth and sensitivity to temperature or pain in the tooth or gums.

How is a root canal performed?

If you experience any of these symptoms, we will most likely recommend treatment to eliminate the diseased pulp. We begin by removing the injured pulp and thoroughly cleaning and sealing the root canal system. This therapy is usually completed in one or more visits, depending on the extent of the treatment required. Success for this type of treatment occurs in about 90% of cases.

We use local anesthesia to eliminate discomfort. In addition, we will provide nitrous oxide analgesia if indicated. Most of our patients are able to drive home after treatment and comfortably return to normal activity right away. If your tooth is not amenable to root canal treatment or the chance of success is unfavorable, you will be informed at the time of consultation or when a complication becomes evident during or after treatment.

What happens after root canal treatment?

When your root canal therapy has been completed, we keep a record of your treatment at our office and schedule a follow-up restoration to be placed within a few weeks. It is rare for endodontic patients to experience complications after routine endodontic treatment or microsurgery. However, if a problem does occur, we are available at all times to evaluate your tooth and proceed as necessary. To prevent further decay, continue to practice good dental hygiene.

Root Canal Therapy FAQs

Is root canal therapy painful?

Root canal therapy is performed using local anesthesia to keep you comfortable throughout the procedure. While you may experience some pressure during treatment, you should not feel significant pain. The procedure helps relieve pain caused by an infected or inflamed tooth, and any mild soreness afterward typically improves within a few days.

Why would I need root canal therapy?

Root canal therapy may be recommended when the pulp inside a tooth becomes infected or inflamed due to deep decay, a crack, trauma, or repeated dental procedures. Treatment removes the affected tissue, cleans and disinfects the inside of the tooth, and seals it to help preserve your natural tooth and prevent further infection.

How long does root canal therapy take?

The procedure typically takes one or two appointments, depending on the condition of the tooth and the complexity of the treatment. Some cases can be completed in a single visit, while others require additional time to address the infection and restore the tooth.

Will I need a crown after root canal therapy?

Many teeth benefit from a dental crown after root canal therapy, particularly back teeth that experience greater chewing forces. A crown helps protect the treated tooth from fractures and restores its strength and function. Your dentist will recommend the appropriate restoration based on the location and condition of your tooth.

How long does a root canal-treated tooth last?

A tooth treated with root canal therapy can last for many years with proper care. Its longevity depends on factors such as the quality of the restoration, oral hygiene, and the amount of healthy tooth structure remaining. Brushing, flossing, and attending regular dental checkups can help protect your treated tooth.

Can a tooth become infected again after root canal therapy?

Yes. Although root canal therapy is designed to eliminate infection, a tooth can occasionally develop a new or persistent infection. This may occur if bacteria reenter the tooth through a damaged restoration, if a canal was difficult to treat, or if new decay develops. Contact your dentist if you experience renewed pain, swelling, or sensitivity around a treated tooth.

Does dental insurance cover root canal therapy?

Many dental insurance plans provide partial coverage for root canal therapy when it is considered medically necessary. Coverage varies depending on your plan, the tooth being treated, and whether additional procedures, such as a dental crown, are needed. Check with your insurance provider or dental office to confirm your benefits before treatment.
