The study, diagnosis, and therapy of the dental pulp and the tissues around the tooth’s root are the focus of the dentistry specialty known as Endodontics, commonly referred to as root canal treatment. The Greek words “endo” and “odont” mean inside and tooth, respectively. During endodontic therapy, a dentist treats the soft pulp tissues located inside the tooth.

A specialist who treats and repairs the soft pulp tissues inside patients’ teeth is called an endodontist. Clinically, endodontists help preserve part or all of the dental pulp in healthy teeth or remove it in infected teeth. This includes cases where the pulpal tissue is irreversibly inflamed or diseased.

If you know little or nothing about Endodontics, the following guide will provide a clear overview of everything related to the treatment.

What Is Endodontics?

A root canal is part of a tooth that contains the pulp, which consists of nerves, blood vessels, and connective tissue. A tooth is made of two main parts:

• Crown – the visible part above the gums
• Root – the portion below the gums that connects the tooth to the jawbone

The pulp is located between the crown and root, inside the root canal. It nourishes surrounding tissues and keeps them healthy.

The term root canal often refers to the dental procedure used to treat infected pulp. Technically, this treatment is called Endodontic therapy, but the phrase root canal is more commonly used.

A root canal is performed when the soft interior pulp becomes infected, inflamed, or injured. Even if the pulp becomes inactive, the crown of the tooth (the visible part) can still remain intact.

Removing the infected pulp is the most effective way to save the tooth.

Why Is a Root Canal Needed?

When pulp becomes damaged or diseased, it cannot heal on its own. Eventually, the tissue dies.

Bacteria can enter the pulp due to:

• Deep cavities
• Cracked teeth
• Loose or damaged fillings

Once bacteria enter the root canal, they can spread infection to the surrounding bone. This can cause:

• Bone weakening and fractures
• Swelling of surrounding ligaments
• Tooth loosening

A damaged pulp can also cause temperature sensitivity, discomfort while chewing, and persistent throbbing pain.

If the infection is left untreated, it can spread further, eventually leading to tooth loss and requiring extraction.

However, losing a tooth can cause nearby teeth to shift and become crooked, affecting both your bite and appearance. Root canal therapy helps save the natural tooth and relieve pain.

Preserving the natural tooth is always the best option because nothing functions as effectively as a real tooth.

Symptoms That Indicate Endodontic Treatment

Causes of Pulp Damage

Common causes that may require endodontic treatment include:

• Tooth injury
• Severe decay caused by untreated cavities
• Multiple dental procedures on the same tooth
• Cracked or chipped teeth

Common Symptoms

Typical signs of pulp damage include:

• Tooth pain or sensitivity
• Swelling around the tooth
• A warm sensation in the affected area
• Persistent discomfort while chewing

To diagnose the problem, the dentist will examine the tooth and take X-rays. If a root canal is required, the dentist may refer the patient to an endodontist for specialized treatment.

Endodontic (Root Canal) Treatment Procedure

Root canal treatment is usually performed in a dental office. During the appointment, the patient is seated comfortably in a treatment chair and prepared for the procedure.

The treatment typically includes four major steps.

1. Providing Anesthesia

The dentist first numbs the gums near the affected tooth using a small amount of anesthesia. Once it takes effect, local anesthesia is injected into the gums.

Patients may feel a brief pinching or burning sensation, but it quickly passes. The patient remains awake throughout the procedure but will not feel pain.

2. Removing the Infected Pulp

Once the tooth is fully numb, the dentist creates a small opening in the top of the tooth.

Using specialized dental instruments, the dentist carefully removes the infected pulp. The canals inside the tooth are then thoroughly cleaned.

3. Applying Antibiotics and Sealing the Canal

After removing the pulp, the dentist may apply an antibiotic to eliminate any remaining bacteria and prevent reinfection.

The canals are then disinfected and filled with a rubber-like material called gutta-percha, which seals the tooth internally.

Sometimes oral antibiotics may also be prescribed.

4. Placing a Temporary Filling

Finally, the dentist seals the small opening in the crown of the tooth using a temporary filling material.

This prevents saliva and bacteria from entering the cleaned canals until a permanent restoration is placed.

Risks of Endodontic Treatment

Root canal treatment is designed to save the natural tooth, but in some cases it may not be possible.

Possible risk factors include:

• Severe tooth damage
• Extremely weak tooth enamel
• Infection that cannot be fully removed

In rare cases, an abscess may develop at the root if bacteria remain or antibiotics are ineffective.

If saving the tooth is not possible, the dentist may recommend tooth extraction and replacement with:

• Dental implants
• Dental bridges
• Temporary dentures

How to Prevent the Need for Endodontic Treatment

Dentists recommend the following practices to prevent tooth decay, infections, and gum disease:

• Brush your teeth before bed and at least once more during the day
• Use fluoride toothpaste
• Replace your toothbrush regularly
• Schedule routine dental checkups and professional cleanings
• Floss daily to remove plaque between teeth
• Limit sugary foods and drinks
• Maintain a balanced and healthy diet
• Use dental sealants to protect teeth from decay
