This is your no-panic, no-jargon guide to root canal treatment — written to help you make confident decisions about your oral health.

2. What Is Root Canal Treatment?

A root canal is a dental procedure that removes infection from inside a tooth while preserving the natural structure.

Inside every tooth is a soft core called pulp — a tiny compartment filled with nerves, blood vessels, and tissues. When this pulp becomes infected due to decay, cracks, or trauma, it causes pain and swelling.

Root canal treatment cleans out this infected pulp, shapes the canals, disinfects them, and seals the space to prevent reinfection.

Think of it as rescuing a damaged tooth from extraction — a final, effective treatment to maintain your natural smile.

3. When Do You Need a Root Canal?

You might need an RCT if you’re experiencing:

• Persistent toothache
• Sensitivity to hot or cold that lingers
• Gum swelling or a small pimple-like boil
• Deep cavities
• Sudden tooth darkening/discoloration
• Pain while chewing

How dentists diagnose it:

• Digital X-rays
• Pulp vitality tests
• Percussion tests
• Clinical examination

If the pulp is infected or dying, an RCT is the best way to save the tooth.

4. Is Root Canal Treatment Painful?

Here’s the part everyone wants to know — does it hurt?
Short answer: Not anymore.

Modern anesthesia = zero pain

Local anesthesia completely numbs the tooth and surrounding tissue. Most patients report no pain during the procedure — just some movement or mild vibrations.

Rotary tools vs old techniques

Older methods used manual files — slower and more uncomfortable.
New-age rotary systems make treatment:

• Faster
• More precise
• More comfortable
• More successful

Pain during vs after treatment

During: Almost always pain-free.
After: Mild soreness for 24–48 hours is normal and manageable with routine painkillers.

Modern dentistry in Kolkata has made RCT a comfortable, predictable, and highly effective treatment.

5. How Does Root Canal Treatment Work? (Step-by-Step)

1. Numbing the area
2. Opening the tooth to access the pulp
3. Cleaning & shaping the canals using rotary files
4. Disinfecting the inside
5. Filling the canals with biocompatible material
6. Sealing the tooth
7. Placing a crown (if required) for strength

6. How Many Visits Are Needed?

Most patients need 1–2 visits.
Severe infections may require a third cleaning session.

7. Why Saving a Tooth Is Better Than Removal

Keeping your natural tooth prevents:

• Shifting of nearby teeth
• Bite imbalance
• Bone loss
• Expensive replacements
• Long-term complications

RCT saves both the tooth and your smile.

8. Crown After Root Canal — Do You Need One?

Back teeth almost always need a crown because they bear heavier chewing forces.
Without a crown, the tooth can crack or break.
Front teeth may not require one unless severely damaged.

9. How Long Does a Root Canal Last?

With proper care + crown, results often last 10–20 years or more. Many last a lifetime.

10. Eating After a Root Canal

• Wait until numbness fades
• Stick to soft foods initially
• Avoid chewing on the treated side
• Resume normal eating after the crown is placed

11. Cost of Root Canal Treatment in Kolkata

Cost varies depending on:

• Number of canals
• Tooth position (front vs molar)
• Equipment used
• Crown material

For an accurate estimate, book a consultation at City Smile Dental Care.

12. Aftercare Tips

• Take prescribed medications
• Avoid hard foods
• Maintain oral hygiene
• Get the crown placed on time
