Root Canal Treatment: Everything You Need to Know About Root Canal Therapy, Causes, and Procedure

What Is Root Canal Treatment?

Root canal treatment (also known as root canal therapy) is a dental procedure used to save a tooth that is infected or severely damaged due to deep decay, cracks, or bacterial infection.

The procedure involves removing the inflamed or infected pulp (nerve), thoroughly cleaning and disinfecting the inner canals of the tooth, and sealing them to prevent further infection. This allows you to preserve your natural tooth instead of extracting it.

When Do You Need a Root Canal?

You may need root canal treatment if you experience any of the following symptoms:

1. Severe, persistent tooth pain

2. Sensitivity to hot or cold that lingers

3. Pain when chewing or biting

4. Swollen, tender gums

5. Tooth discoloration

6. An abscess or pus around the tooth

⚠️ In some cases, symptoms may not be obvious. Therefore, regular dental check-ups are essential for early detection.

Causes of Tooth Nerve Infection

The most common causes of pulp (nerve) infection include:

1. Untreated deep tooth decay

2. A cracked or fractured tooth

3. Repeated dental procedures on the same tooth

4. Trauma or injury to the tooth

Early treatment helps prevent complications and increases the chances of saving the tooth.

Steps of the Root Canal Procedure

Root canal treatment is usually completed in one or two visits, depending on the severity of the infection. The procedure typically includes:

1. Local anesthesia to ensure maximum comfort

2. Creating a small opening in the crown of the tooth

3. Removing the infected or inflamed pulp

4. Cleaning and disinfecting the root canals thoroughly

5. Filling the canals with a biocompatible material

6. Sealing the tooth with a permanent filling or placing a dental crown for protection

Is Root Canal Treatment Painful?

Thanks to modern dental techniques and effective local anesthesia, root canal treatment is generally not painful.

After the procedure, mild discomfort, tenderness, or slight pressure may occur; however, these symptoms usually subside within a few days.

How Long Does a Root Canal Take?

1. Typically, 60–90 minutes per session

2. Complex cases may require more than one appointment

Aftercare Tips Following Root Canal Treatment

To ensure proper healing and long-term success:

1. Avoid chewing on the treated tooth until it is permanently restored

2. Maintain good oral hygiene by brushing and flossing daily

3. Attend all scheduled follow-up appointments

4. Consider placing a dental crown to prevent fracture

Frequently Asked Questions About Root Canal Treatment

• Is root canal treatment painful?

No. The procedure is performed under local anesthesia, so patients do not feel pain during treatment. Mild discomfort afterward is normal and temporary.

• How many visits are needed for a root canal?

In most cases, one visit is sufficient. However, if there is severe infection or an abscess, two visits may be required.

• Can I eat after a root canal?

Yes; however, you should wait until the numbness wears off. Avoid chewing on the treated tooth until it is restored with a permanent filling or crown.

• Is a dental crown necessary after a root canal?

In most cases—especially for molars—a dental crown is highly recommended to strengthen and protect the tooth, extending its lifespan.

• What are the signs of a failed root canal?

Signs may include:

1. Persistent, severe pain

2. Gum swelling

3. Abscess formation

4. Ongoing sensitivity

If you notice any of these symptoms, contact your dentist immediately.

• What is the difference between a root canal and tooth extraction?

A root canal removes the infection while preserving your natural tooth. In contrast, tooth extraction removes the entire tooth and may require replacement with a dental implant or bridge.

• How long does a root canal last?

With proper care and good oral hygiene, a root canal-treated tooth can last for many years—sometimes even a lifetime.
