What Is Root Canal Therapy?

When a tooth becomes infected or severely damaged, it can cause significant discomfort and affect your daily function. At Westowne Dental, root canal therapy is used to remove infection from inside the tooth while preserving its natural structure.


The procedure involves carefully cleaning the inner portion of the tooth, removing infected tissue, and sealing the space to prevent future issues. This allows you to keep your natural tooth while relieving pain and restoring function. Root canal therapy may help:

When Is Root Canal Therapy Needed?

Root canal therapy is typically recommended when the inner portion of the tooth, known as the pulp, becomes infected. This can occur due to deep decay, cracks, trauma, or previous dental treatment that has weakened the tooth.


If left untreated, the infection can worsen and lead to more complex concerns. Early diagnosis and treatment can help preserve your natural tooth and avoid more extensive procedures.


You may need a root canal if you experience persistent tooth pain or sensitivity, swelling in the gums or jaw, discomfort when chewing or biting, or signs of infection such as an abscess. If you are unsure about your symptoms, our team can assess your condition and recommend the appropriate treatment.

Root Canal Therapy FAQs

Frequently Asked Questions

  • What happens during a root canal procedure?

    The infected tissue inside the tooth is removed, the area is cleaned and disinfected, and the tooth is sealed to prevent further infection. A restoration, such as a crown, may be placed afterward to protect the tooth.

  • Is root canal therapy painful?

    The procedure is performed with local anesthesia to keep you comfortable. Most patients find that it relieves the pain caused by infection rather than causing discomfort.

  • How long does a root canal take?

    Treatment is often completed in one or two visits, depending on the condition of the tooth and the complexity of the case.

  • Can a tooth last after a root canal?

    Yes. With proper care and restoration, a tooth treated with root canal therapy can last many years.

  • What should I expect after treatment?

    You may experience mild sensitivity for a few days, but this typically resolves quickly. Following aftercare instructions and attending follow-up visits helps ensure proper healing.
