Root Canal Treatment: What You Really Need to Know (2026 Guide)

What Is a Root Canal?

Think of a root canal as a way to rescue a tooth that has become infected or inflamed in its pulp (nerve). Instead of extracting the tooth, the dentist removes the damaged tissue, cleans the canals, and fills them.

Why You Might Need a Root Canal

  • Deep decay that has reached the nerve
  • A crack or fracture exposing the pulp
  • Severe, persistent toothache
  • Swelling or abscess near the tooth
  • Extreme sensitivity to hot or cold that lingers

The Procedure at Cosmo Dental

First: Accurate Diagnosis
We use digital X-rays and 3D CBCT scans to map every canal and assess the infection precisely.

Then: Anesthesia
Advanced local anesthesia ensures you feel nothing during the entire procedure.

Next: Removing Infected Tissue
Using precise rotary instruments, we remove the infected pulp and thoroughly clean all root canals.

Finally: Filling and Restoration
Canals are sealed with biocompatible material, then a crown is placed to protect the tooth and restore full function.

Does It Hurt?

The truth: Modern root canal treatment is not painful! With advanced anesthesia and current techniques, most of our patients describe it as similar to getting a regular filling.

How Long Does It Take?

Here at Cosmo, most root canal cases are completed in a single session lasting 45–90 minutes, thanks to our advanced technology and experienced endodontists.

After we are done

  • Mild soreness for 2–3 days (over-the-counter painkillers are sufficient)
  • Avoid chewing on the treated side for two days
  • Follow-up visit after one week to confirm healing
  • Crown placement within two weeks to protect the tooth
