If a dull ache in your tooth has turned into a sharp, throbbing pain, your dentist has probably mentioned root canal treatment. And naturally, your next question is: how much will it cost?
It’s a fair question. Root canal treatment isn’t cheap, and prices in Kolkata can range quite a bit depending on the tooth involved, the clinic you choose, and whether you need a crown afterward. This guide breaks down real numbers, explains what affects the price, and helps you understand what you’re actually paying for so you can make an informed decision without guesswork.
Quick Summary Box
- Average RCT cost in Kolkata: ₹3,500 – ₹12,000 per tooth (excluding crown)
- With crown: ₹6,000 – ₹25,000 depending on crown material
- Single sitting RCT: Slightly higher per visit but saves time
- Front teeth are generally cheaper than molars
- Treatment usually takes 1 to 3 sittings of 30–60 minutes each
- Success rate with proper aftercare is high, though not guaranteed in every case
What Is Root Canal Treatment?
Root canal treatment (RCT) is a dental procedure that removes infected or inflamed pulp tissue from inside a tooth, cleans the canal, and seals it to prevent further infection. It’s performed by a general dentist or, in more complex cases, an endodontist a specialist trained specifically in treating the inside of the tooth.
The pulp contains nerves and blood vessels. Once bacteria reach it, usually through deep tooth decay, a crack, or repeated dental procedures, the tooth can’t heal on its own. Left untreated, the infection can spread to the bone around the root.
Why Do You Need a Root Canal?
Common causes include:
- Deep cavities left untreated
- Cracked or fractured teeth
- Repeated dental work on the same tooth
- Trauma or injury to a tooth
- Gum disease that has reached the root
Common symptoms that suggest you might need one:
| Symptom | What It Usually Means |
|---|---|
| Lingering pain with hot/cold | Pulp inflammation |
| Pain while chewing | Possible infection near root |
| Swollen gums near a tooth | Abscess or infection |
| Tooth darkening | Pulp death |
| Persistent bad taste | Draining infection |
If any of this sounds familiar, it’s worth getting an X-ray done rather than waiting it out.
Root Canal Treatment Cost in Kolkata
On average, root canal treatment in Kolkata costs between ₹3,500 and ₹12,000 per tooth, not including the crown. This is broadly in line with pricing across most metro cities in India, though it can vary by clinic reputation, technology used, and the complexity of the case.
Root Canal Cost by Tooth Type
Molars have more canals and take longer to treat, which is why they typically cost more than front teeth.
| Tooth Type | Approximate Cost (RCT only) |
|---|---|
| Front tooth (Incisor) | ₹3,500 – ₹5,500 |
| Premolar | ₹4,500 – ₹7,500 |
| Molar | ₹6,000 – ₹12,000 |
These are indicative figures your dentist will confirm exact pricing after an X-ray and clinical exam.
Single Sitting vs Multiple Sitting Root Canal Cost
| Factor | Single Sitting RCT | Multiple Sitting RCT |
|---|---|---|
| Number of visits | 1 | 2–3 |
| Time per visit | 60–90 minutes | 30–45 minutes each |
| Best suited for | Non-infected or mildly infected teeth | Severely infected teeth |
| Cost | Slightly higher per visit | Spread across visits |
| Convenience | Ideal for working professionals | Better for complex infections |
Single sitting root canal treatment has become popular in Kolkata among working professionals who can’t take multiple days off. That said, your dentist will recommend the approach based on how infected the tooth is not personal convenience alone.
Root Canal with Crown Cost
A crown protects the treated tooth from fracturing, especially for molars that bear heavy chewing force. Skipping the crown when it’s clinically recommended is one of the most common mistakes patients make.
| Crown Type | Approximate Cost |
|---|---|
| Metal Ceramic (PFM) Crown | ₹3,000 – ₹6,000 |
| Zirconia Crown | ₹8,000 – ₹15,000 |
| Full Ceramic Crown | ₹10,000 – ₹18,000 |
So, a molar root canal with a zirconia crown could realistically total ₹14,000 – ₹27,000, while a front tooth RCT with a metal ceramic crown may fall closer to ₹6,500 – ₹11,500.
Factors That Affect Root Canal Cost
| Factor | Impact on Cost |
|---|---|
| Tooth location (front vs molar) | Molars cost more |
| Number of canals | More canals = more time = higher cost |
| Severity of infection | Complex infections may need extra visits |
| Type of crown chosen | Zirconia costs more than PFM |
| Clinic technology (rotary, microscope) | May add to cost but improves precision |
| Dentist’s experience | Specialist endodontists may charge more |
| Location within the city | South Kolkata clinics vary from suburban ones |
Is Root Canal Painful?
This is probably the most common concern, and the honest answer is: modern root canal treatment is done under local anaesthesia, so the procedure itself is largely painless. Most patients describe it as similar to getting a filling done. Some mild soreness for a day or two afterward is normal and manageable with prescribed medication.
Recovery and Aftercare
Recovery Timeline
| Day | What to Expect |
|---|---|
| Day 1–2 | Mild soreness, slight sensitivity |
| Day 3–5 | Discomfort reduces significantly |
| Week 1–2 | Crown placement (if pending) |
| Month 1 | Tooth functions normally |
Foods to eat: Soft foods, warm soups, mashed vegetables, yogurt.
Foods to avoid: Hard, sticky, or very hot/cold foods until the crown is placed.
Basic aftercare includes gentle brushing, avoiding chewing directly on the treated tooth, and attending your follow-up for the crown.
Success Rate and Risks
Root canal treatment has a generally high success rate when performed correctly and followed by a crown where needed. That said, no medical procedure is guaranteed. Rare complications can include reinfection, missed canals, or crown-related issues, which is why follow-up visits matter.
Myths vs Facts
| Myth | Fact |
|---|---|
| Root canals are extremely painful | They’re done under anaesthesia; pain is minimal |
| Extraction is always cheaper long-term | Implants/bridges after extraction often cost more overall |
| A root canal tooth doesn’t need a crown | Molars especially need crowns to prevent fracture |
| One sitting always means better treatment | Approach depends on infection severity, not convenience |
FAQs
1. How much does root canal treatment cost in Kolkata?
It generally ranges from ₹3,500 to ₹12,000 per tooth, excluding the crown. Molars cost more than front teeth due to the extra canals and time involved. Your dentist will give an exact estimate after examining the tooth and reviewing an X-ray.
2. Is single sitting root canal treatment more expensive?
It can be slightly higher per visit since more work is done in one sitting, but it often works out similar overall since you save on multiple visit charges. It’s best suited for teeth without severe infection.
3. Do I always need a crown after a root canal?
Not always, but it’s strongly recommended for molars and premolars since they bear heavy chewing pressure. Front teeth sometimes don’t need a full crown, depending on how much tooth structure remains.
4. Is root canal treatment safe for senior citizens?
Yes, it’s routinely performed on senior citizens. Your dentist will review your medical history and any medications before planning the procedure to ensure it’s done safely.

When Should You Consult a Root Canal Specialist?
Don’t wait for the pain to become unbearable before seeking care. Persistent sensitivity to hot or cold, pain while chewing, gum swelling, or a tooth that feels “different” from the rest are all signs worth getting checked promptly. Delaying treatment can allow the infection to spread to the bone, sometimes turning a straightforward root canal into a more complex — and costlier — procedure. An early X-ray and consultation can save you both discomfort and expense down the line.
