A constant toothache isn’t just annoying—it could mean there’s an infection inside your tooth. If a dentist has suggested a root canal, you might feel nervous or unsure about the process. But don’t worry—modern root canal treatments are safe and painless and help save your natural tooth from being removed.
This guide will explain everything you need to know about root canals, including why they’re needed, how the procedure works, what to expect during recovery, and how to care for your tooth afterward.
What Is Root Canal Treatment?
A root canal, also called endodontic therapy, is a procedure to remove infected or inflamed tissue from inside a tooth. This soft tissue, known as the pulp, contains nerves and blood vessels, but a fully developed tooth can survive without it by getting nutrients from nearby tissues.
During the procedure, the dentist extracts the infected pulp, carefully cleans and disinfects the inner tooth, and seals it with a durable filling material. To strengthen and safeguard the tooth from further damage, a filling or crown is placed on top.
When Is Root Canal Treatment Needed?
A root canal is required when the pulp inside a tooth gets infected or inflamed due to:
- Deep decay that has reached the pulp.
- Repeated dental procedures on the same tooth.
- Cracks or fractures that expose the pulp to bacteria.
- Trauma that causes pulp damage, even without visible cracks.
Signs You May Need a Root Canal
- Persistent or severe tooth pain, especially while chewing.
- Sensitivity to hot or cold that stays even after the source is removed.
- Swollen or tender gums near the affected tooth.
- Darkening or discoloration of the tooth.
- A pimple-like bump on the gums indicates an abscess.
- Bad taste or pus discharge due to infection.
The Root Canal Procedure: Step-by-Step Guide
Many people believe root canals are painful, but modern anaesthesia and advanced dental technology make the procedure almost pain-free. Depending on the extent of the infection, treatment is usually completed in one to three appointments.
- Step 1: Examination and Anaesthesia: Your dentist will first take X-rays to assess the severity of the infection. Once confirmed, a local aesthetic is applied to numb the area, ensuring the procedure is painless and comfortable.
- Step 2: Creating an Access Opening: A small opening is made on the affected tooth to access the pulp chamber and root canals.
- Step 3: Removing the Infected Pulp and Cleaning: The damaged or infected pulp is gently removed, and the canals are cleaned, shaped, and disinfected to remove bacteria and reduce the risk of future infection.
- Step 4: Filling and Sealing the Canals: The empty canals are filled with gutta-percha, a biocompatible rubber-like material, to seal and protect them from future infections. A temporary filling is placed on top.
- Step 5: Restoring the Tooth: Since a root canal-treated tooth is more fragile, a permanent filling or dental crown is placed to restore its strength and function. Until the final restoration is completed, avoid chewing on the treated tooth.
How Long Does a Root Canal Take?
The time required for a root canal procedure varies based on the tooth’s location and the extent of the infection.
- Front teeth (single-rooted): 60 – 90 minutes
- Molars & premolars (multi-rooted): 90 – 120 minutes
- Complex cases with severe infection: May require multiple visits
What to Expect After a Root Canal?
After the procedure, it is normal to experience mild sensitivity or discomfort for a few days due to tissue inflammation. However, this discomfort can be managed by taking over-the-counter pain relievers like ibuprofen or acetaminophen.
Post-Treatment Care Tips:
- Avoid chewing on the treated tooth until the final restoration is placed.
- Practice proper oral hygiene by brushing and flossing regularly.
- Attend follow-up visits with the dentist to ensure proper healing and restoration placement.
- If swelling or severe pain persists, contact your dentist immediately.
With proper care, a root canal-treated tooth can last a lifetime.

FAQs
What should I know before getting a root canal?
A root canal treatment is a routine procedure that relieves pain and saves natural teeth. Thanks to modern anesthesia, it is virtually painless and helps prevent the need for tooth extraction. A crown may be required afterward for added protection.
Is a root canal painful?
With local anesthesia, the procedure is not painful. Most discomfort occurs after the treatment, but it can be managed with pain relievers. If severe pain persists, consult your dentist.
How long does it take to recover from a root canal?
Most patients recover within a few days. Some mild sensitivity or discomfort is normal, but regular activities can be resumed within 24–48 hours.
How much does a root canal cost?
The cost of root canal treatment varies by tooth type and complexity, typically ranging between ₹5,000 – ₹15,000. Molars cost more due to their multiple root canals.
Do I need a crown after a root canal?
Yes, most teeth require a crown to prevent fractures. Front teeth may only need a permanent filling, but molars and premolars benefit from a dental crown for durability.
Can I eat after a root canal?
Wait for the numbness to go away before eating. Choose soft foods for a few days and avoid putting extra pressure on the treated tooth until it has been fully restored.
