A root canal may be needed when the pulp—the soft tissue inside the tooth containing nerves and blood vessels—becomes inflamed, infected, or no longer vital. This can happen because of deep decay, a crack or fracture, dental trauma, or previous dental treatment.

The goal of root canal treatment is to remove the affected tissue, disinfect the inside of the tooth, and preserve the natural tooth whenever possible.

Not every toothache means you need a root canal. Symptoms such as lingering sensitivity to hot or cold, spontaneous pain, pain when biting, swelling, or a recurring bump on the gums can indicate inflammation or infection inside the tooth. Clinical testing and dental imaging are needed to determine whether root canal treatment is actually necessary.

Yes. Some teeth that require root canal treatment cause little or no pain.

A tooth may lose vitality slowly or develop an infection without producing noticeable symptoms. In some cases, the problem is first identified on a dental X-ray or during routine testing.

This is why diagnosis is based on more than symptoms alone. Clinical testing and dental imaging help determine whether the pulp inside the tooth is healthy, inflamed, infected, or no longer vital.

After the tooth is thoroughly numbed, a small opening is made to access the root canal system. The inflamed or infected tissue is removed, and the canals are carefully cleaned, disinfected, shaped, and sealed.

Treatment is performed with specialized instruments and magnification to help identify and treat the internal anatomy of the tooth as precisely as possible. In some cases, 3D CBCT imaging may be used to better understand the anatomy of the tooth or surrounding structures. Depending on the tooth and the clinical situation, treatment may be completed in one or more visits.

Modern root canal treatment is performed with local anesthesia, and most patients are comfortable during the procedure. Our goal is to make treatment as relaxed and predictable as possible.

It is normal for the tooth and surrounding tissues to feel tender for a few days afterward, particularly when biting or chewing. This discomfort is usually temporary and gradually improves as the area heals.

Some tenderness or sensitivity to biting is common for several days after root canal treatment. Until the tooth has been permanently restored, avoid chewing hard or sticky foods on that side whenever possible.

In many cases, the tooth will need a final restoration—often a crown—to protect it from fracture and restore normal function. We will communicate with your general dentist regarding the appropriate next step and timing for your permanent restoration.

Follow-up may also be recommended to evaluate healing around the tooth. If a previously treated tooth develops new symptoms in the future, root canal retreatment may sometimes be considered.

Endodontists are dental specialists who focus on diagnosing tooth pain and treating conditions involving the dental pulp and tissues surrounding the roots of teeth.

After dental school, endodontists complete additional specialty training dedicated to root canal treatment, complex diagnosis, retreatment, dental trauma, and endodontic surgery. Their practices are limited to endodontic care, allowing them to perform these procedures routinely using specialized technology, magnification, and techniques designed for complex root canal anatomy.
