What Is Root Canal Treatment?

Root canal treatment is a dental procedure designed to treat infection or inflammation within the inner portion of the tooth known as the dental pulp. The pulp contains nerves and blood vessels that help the tooth develop, but once a tooth is fully mature it can function without this tissue.

When bacteria enter the pulp due to deep decay, cracks, trauma, or repeated dental procedures, infection can develop. Root canal therapy removes the infected tissue, cleans the root canal system, and seals the tooth to prevent reinfection.

This treatment is part of the specialized field of Endodontics, which focuses on diagnosing and treating conditions affecting the inside of the tooth.

With proper restoration after treatment, many root canal–treated teeth can last a lifetime.

Signs You May Need a Root Canal

Common symptoms that may indicate the need for root canal treatment include:

• Severe or persistent tooth pain
• Sensitivity to hot or cold temperatures
• Pain when chewing or biting
• Swelling or tenderness in nearby gums
• Darkening or discoloration of a tooth
• A small bump or abscess on the gums

In some cases, infection may be present even when symptoms are mild or absent. Using advanced imaging described on our Advanced Technology page, our specialists can identify problems that may not be visible with standard dental exams.

The Root Canal Treatment Process

Root canal therapy is typically completed in one or two visits depending on the complexity of the tooth.

Diagnosis and Imaging

Your endodontist begins by examining the tooth and taking detailed images to determine the extent of infection.

Local Anesthesia

The tooth and surrounding tissues are numbed so the procedure can be performed comfortably.

Cleaning the Root Canal System

The infected pulp is removed from the inside of the tooth, and the root canals are carefully cleaned and disinfected.

Sealing the Tooth

The cleaned canals are filled and sealed to prevent bacteria from reentering the tooth.

Final Restoration

After treatment, your general dentist usually places a crown or restoration to protect the tooth and restore full function.

In some situations, additional procedures such as Endodontic Retreatment or Apicoectomy (Root-End Surgery) may be recommended if infection persists.

Does Root Canal Treatment Hurt?

One of the most common misconceptions about root canal treatment is that it is painful. In reality, modern root canal therapy is designed to relieve pain rather than cause it.

With today’s advanced anesthetics and treatment techniques, most patients report that the procedure feels similar to receiving a dental filling.

Root canal treatment removes the infected tissue that is typically responsible for tooth pain, allowing the tooth and surrounding tissues to heal.

Root Canal Safety and Scientific Evidence

Root canal therapy has been performed safely for decades and is supported by extensive scientific research.

Some misinformation about root canals originates from a long-discredited theory from the early 1900s suggesting that root canal–treated teeth could cause systemic disease. Modern studies have consistently disproven this claim.

Organizations such as the American Association of Endodontists confirm that root canal treatment safely eliminates infection and helps preserve natural teeth. In fact, saving the natural tooth is often the best option for maintaining long-term oral health.

Root Canal Treatment vs Tooth Extraction

When a tooth becomes severely infected, patients may wonder whether extraction is a better option. In most cases, saving the natural tooth is the preferred solution.

Benefits of root canal treatment include:

• Preserving your natural tooth structure
• Maintaining normal chewing ability
• Preventing surrounding teeth from shifting
• Avoiding more complex replacement procedures
• Lower long-term treatment costs in many cases

Extraction often requires replacement with an implant, bridge, or denture, which can involve additional treatment time and cost.

Root Resorption and Root Canal Therapy

In rare cases, teeth may develop a condition called root resorption, where the body begins breaking down the tooth’s root structure.

This condition may occur due to trauma, orthodontic pressure, or chronic inflammation. Root resorption often progresses without noticeable symptoms and may only be detected through dental imaging.

When diagnosed early, root canal therapy may help stop the progression of resorption and preserve the tooth. Early evaluation by an endodontist is essential for the best outcome.
