Endodontics (Root Canal Treatment)

The Most Effective Way to Save a Tooth: What Is Root Canal Treatment?
Endodontics, commonly known as “root canal treatment,” is a dental procedure applied when the tooth’s inner nerve and vascular tissues become infected. Due to deep decay, trauma, or damaged old fillings, the dental pulp (nerve tissue) may become inflamed or die. During treatment, this infected tissue is removed, the canals are shaped and disinfected, and then filled with a special sealing material. As a result, the tooth can remain functional and healthy in the mouth for many years without extraction.

Root canal treatment is not merely a “last resort” to save a tooth—it is a modern, reliable, and long-term solution when performed correctly.

When Is Root Canal Treatment Needed?

• When decay reaches the nerve of the tooth

• Following dental trauma (fractures, cracks)

• Sensitivity after deep fillings

• Persistent toothache, throbbing pain, or night pain

• Abscess or swelling in the gums

• Tooth discoloration (a sign of pulp death)

How Is Root Canal Treatment Performed?

1. Examination and X-ray: The extent and location of the infection are determined.

2. Anesthesia: The area is numbed to ensure a painless procedure.

3. Canal Cleaning: The infected pulp and tissues are removed, and the canals are disinfected.

4. Canal Filling: The cleaned and shaped canals are sealed with a special filling material.

5. Restoration: The tooth may be restored with a filling or crown to ensure durability.

With today’s advanced dental technologies, most root canal treatments can be completed in a single session.

Advantages of Root Canal Treatment

• Preserves the natural tooth in the mouth

• Maintains chewing function and aesthetic appearance

• Prevents or delays the need for tooth extraction and prosthetics

• Stops the spread of infection and bone loss

• Has a success rate of over 95% when properly performed

Post-Treatment Care

• Temporary sensitivity after treatment is normal

• Avoid hard foods for the first 24 hours

• Do not bite directly on the treated tooth until restoration is complete

• Crowning may be recommended to strengthen the tooth

• Maintain regular oral hygiene and dental check-ups

Frequently Asked Questions

1. Is root canal treatment painful?
   No. The procedure is performed under local anesthesia, ensuring comfort. Mild soreness may follow but resolves quickly.

2. Can root canal treatment be done in one session?
   Yes. Most simple cases are completed in a single visit. However, multiple sessions may be needed for advanced infections.

3. How long does a root canal-treated tooth last?
   When properly done and maintained, such teeth can last 10–20 years or even a lifetime.

4. Will my tooth become fragile after treatment?
   The tooth structure becomes slightly weaker, so a crown may be recommended to prevent fractures.

5. What if root canal treatment fails?
   In such cases, the canal can be retreated (retreatment). For persistent cases, an apical resection (root-end surgery) may be required.
