Hearing the words root canal treatment often makes people nervous. Many patients delay treatment because they believe it’s painful, risky, or unnecessary. But the truth is, modern root canal procedures are safe, comfortable, and one of the best ways to save a natural tooth.
In this blog, a dentist explains the most common root canal myths, answers the big question “is root canal painful?”, shares the root canal cost in India, and helps you understand life after RCT including how long does root canal last and whether root canal vs extraction is the better choice.
What Is Root Canal Treatment?
Root canal treatment (RCT) is a dental procedure used to remove infection from inside the tooth. The inside portion of the tooth contains soft tissue called pulp, which can become infected due to deep cavities, cracks, or injury.
During RCT, the infected pulp is removed, the canals are cleaned and disinfected, and the tooth is sealed to prevent reinfection.
✅ Root canal treatment helps you:
- Save your natural tooth
- Stop tooth pain and infection
- Avoid tooth extraction
- Restore chewing and normal function
When Do You Need Root Canal Treatment?
You may need root canal treatment if you experience:
- Severe toothache while chewing or biting
- Sensitivity to hot/cold that lasts long
- Swelling or pus near the tooth (gum boil)
- Tooth discoloration
- Pain that spreads to jaw/ear
- Deep cavity close to the nerve
Sometimes, a tooth infection can be silent. That’s why regular dental checkups are important.
Is Root Canal Painful? (Dentist’s Honest Answer)
Let’s answer the most searched question: is root canal painful?
✅ Root canal treatment is not painful in most cases, because the procedure is done under local anesthesia. Patients usually feel pressure, but not sharp pain.
What You Might Feel During RCT
- Mild pressure while cleaning the canals
- Slight discomfort from keeping mouth open
- No major pain due to anesthesia
After the Procedure
Some mild soreness for 1-3 days is normal, especially when biting. This can be managed with painkillers prescribed by your dentist.
Truth: Root canal treatment actually relieves the pain caused by infection.
Root Canal Myths vs Facts (Must Know!)
Many people fear RCT due to misinformation. Let’s clear the most common root canal myths:
Myth 1: Root Canal Treatment Is Extremely Painful
✅ Fact: With modern techniques and anesthesia, RCT is usually as comfortable as getting a filling.
Myth 2: It’s Better to Remove the Tooth
✅ Fact: Saving your natural tooth is almost always the best option. Extraction may lead to further expenses like implants or bridges.
Myth 3: Root Canal Weakens the Tooth Forever
✅ Fact: A tooth becomes stronger and functional again when restored properly with a crown.
Myth 4: Root Canal Causes Other Health Problems
✅ Fact: This is one of the oldest root canal myths. There’s no valid modern evidence proving root canal causes systemic diseases.
Myth 5: One RCT Means No More Dental Problems
✅ Fact: The tooth still needs good oral hygiene and usually a crown to prevent fracture.
Root Canal Treatment Procedure (Step-by-Step)
Here’s how a typical root canal treatment is done:
1. Diagnosis & X-Ray
The dentist checks the infection level and number of canals using an X-ray or digital scan.
2. Local Anesthesia
The tooth is numbed completely to ensure comfort.
3. Removing the Infection
An opening is made, and infected pulp is removed.
4. Cleaning & Shaping the Canals
The canals are cleaned and disinfected to remove bacteria.
5. Filling the Canals
They are sealed with a biocompatible material to prevent reinfection.
6. Tooth Restoration
A temporary or permanent filling is placed. In most cases, a crown is recommended for long-term strength.
Root Canal Cost in India (2026 Guide)
The root canal cost in India depends on multiple factors such as the tooth type, number of canals, infection severity, and technology used.
Average Root Canal Cost in India
✅ Typical range: ₹4,500 to ₹15,000 per tooth
What Affects the Root Canal Cost in India?
- Front tooth vs molar (molars cost more due to more canals)

Note: It’s best to ask for a complete estimate including crown placement.
Root Canal vs Extraction: Which One Is Better?
Patients often ask about root canal vs extraction when tooth pain becomes unbearable.
| Factor | Root Canal Treatment | Tooth Extraction |
| Main Goal | Saves the natural tooth by removing infection | Removes the damaged/infected tooth completely |
| Pain Relief | Relieves pain by cleaning infected pulp | Relieves pain by removing the tooth |
| Tooth Preservation | ✅ Yes, your original tooth is saved | ❌ No, tooth is removed permanently |
| Chewing & Function | ✅ Maintains normal chewing and bite | ⚠️ May reduce chewing ability until replaced |
| Impact on Nearby Teeth | ✅ No shifting when tooth is saved | ❌ Nearby teeth may shift into the empty space |
| Jawbone Health | ✅ Helps maintain jawbone strength | ❌ Bone loss can happen over time in the missing tooth area |
| Treatment Time | Usually 1–2 visits (depends on infection) | Single visit, but replacement takes extra time |
| Long-Term Solution | ✅ Strong and lasting with crown | ❌ Needs replacement (implant/bridge/denture) for function |
| Cost Comparison | Moderate cost | Extraction is cheaper initially, but replacement costs more |
| Best For | Teeth that can be saved and restored | Teeth that are severely broken or beyond repair |

FAQs About Root Canal Treatment (Quick Answers)
1. Is root canal treatment painful?
Most patients do not feel pain during a root canal because the tooth is numbed with local anaesthesia. You may feel pressure or mild discomfort, but not sharp pain.
2. Which hurts more: root canal or tooth extraction?
With proper anaesthesia, both procedures can be done comfortably. However, a root canal usually causes less post‑treatment discomfort than an extraction followed by replacement procedures.
3. How much does a root canal cost in India?
In India, the cost of a root canal typically ranges from about ₹4,500 to ₹15,000 per tooth, depending on tooth type, number of canals, infection severity, and clinic location.
4. Why do molar root canals cost more?
Molars have more roots and canals, making the procedure more complex and time‑consuming. They may also require advanced equipment, which adds to the cost.
5. How long does a root canal last?
A well‑done root canal with a proper crown and good oral hygiene can last 10–20 years or even a lifetime in many cases.
