What Is Root Canal Treatment?

A root canal treatment is a dental procedure that removes infection from the inside of a tooth to save it from extraction. When the soft tissue inside the tooth, called the pulp, becomes infected due to deep decay or injury, it causes severe pain and sensitivity. A root canal cleans this infected part, disinfects the inside of the tooth and seals it to prevent further damage.

Simply put, RCT helps save your natural tooth, stops pain, and restores full chewing ability. Once the infection is removed and the tooth is restored with a crown, it functions just like any other healthy tooth.

Signs You May Need a Root Canal

Root canal treatment is usually needed when the inner part of the tooth becomes infected or inflamed. These symptoms often start mildly but gradually become more severe if ignored. Recognizing the early signs can help prevent the infection from spreading and avoid tooth loss.

Common Symptoms to Watch For:

Pain that lingers, especially while chewing or applying pressure, is one of the most common root canal infection symptoms.

If your tooth aches even after removing the hot or cold stimulus, it may indicate pulp inflammation.

Swollen, puffy or painful gums around the affected tooth often point to an underlying infection.

A tooth turning grey or dark can be a sign of nerve damage inside the tooth.

Large, untreated cavities can reach the nerve, making a root canal the only way to save the tooth.

A small boil or bump (gum boil) near the tooth often indicates infection draining from the root.

Increased sensitivity when pressing or touching the tooth may signal nerve involvement.

How Our Root Canal Treatment Works

Our root canal specialist in South Kolkata follows a precise, step-by-step process to ensure your treatment is safe, painless and long-lasting. Every stage is performed using modern endodontic techniques, digital X-rays and rotary instruments for maximum accuracy and comfort.

Below is a clear breakdown of what happens during a root canal treatment:

1. Diagnosis and Digital Assessment

Your treatment begins with a thorough examination and a digital X-ray to find the exact location and extent of infection. This helps us understand whether the pulp is inflamed, if there is an abscess, and whether a root canal is the best solution. Accurate diagnosis ensures predictable and successful treatment.

2. Gentle, Local Anesthesia for a Pain-Free Experience

Before starting the procedure, we numb the affected tooth and surrounding area using a gentle and safe anesthesia technique. This ensures that you remain completely comfortable throughout the treatment. Most patients are surprised to learn that modern root canal therapy feels very similar to a regular filling.

3. Cleaning the Infected Pulp

Once your tooth is numb, a small opening is made on the top of the tooth to reach the infected pulp. The infected or damaged tissue is carefully removed using specialized tools. This step eliminates the bacteria inside the root and stops the infection from spreading further.

4. Shaping the Root Canals with Rotary Tools

After cleaning, the canals are shaped using advanced rotary instruments. These tools help create smooth, precise canal shapes, allowing better disinfection and ensuring that the filling material seals the root completely. This step is important for long-term success and reduces the chance of re-infection.

5. Disinfection and Filling of the Canals

The cleaned and shaped canals are then disinfected thoroughly with antibacterial solutions. After drying, they are filled with a biocompatible material called gutta-percha, which seals the canals and prevents bacteria from re-entering. This restores the inner strength of the tooth.

6. Crown Placement to Protect the Tooth

Because a root canal-treated tooth becomes slightly weaker, we recommend placing a dental crown over it. The crown adds strength, protects the tooth from fractures and restores natural chewing function. Once the crown is placed, the tooth functions just like any healthy tooth.

Benefits of Getting a Root Canal at the Right Time

Treating an infected tooth early is one of the best ways to protect your oral health and avoid complicated dental issues later. When a root canal is performed at the right stage, it not only relieves pain but also helps save the natural tooth and prevents the infection from spreading to surrounding tissues.

Here are the key benefits of timely root canal treatment:

1. Immediate Relief from Pain and Sensitivity

Early treatment removes the inflamed nerve tissue and stops the discomfort caused by chewing, pressure, hot or cold sensations. Most patients feel significant relief shortly after the procedure.

2. Saves Your Natural Tooth from Extraction

A timely RCT cleans and seals the tooth before the infection worsens. Keeping your natural tooth is always better for chewing, appearance and long-term oral function.

3. Prevents Infection from Spreading

Untreated infection can spread to the gums, jawbone and even other parts of the body. Root canal therapy stops the infection at its source and protects surrounding tissues.

4. Restores Chewing Strength and Function

Once treated and protected with a crown, the tooth becomes strong again and can function just like a healthy natural tooth. You can chew comfortably without fear of pain.

5. Protects Overall Oral and General Health

Dental infections can sometimes cause swelling, abscesses and systemic issues. Treating the infection early helps maintain both oral and general well-being.

6. Reduces the Need for Costly Future Treatments

Delaying treatment often leads to complications that require more complex procedures such as extractions, implants or full-mouth rehabilitation. A timely RCT is always more cost-effective.

Frequently Asked Questions About Root Canal Treatment

Q1. Is a root canal painful?

No. Modern root canal treatment is performed under local anesthesia, making the procedure completely comfortable. Most patients say it feels like getting a regular filling. Any mild soreness after the procedure usually settles within a day or two.

You may need a root canal if you experience severe tooth pain, lingering sensitivity to hot or cold, swelling in the gums, a pimple-like bump on the gums or tooth discoloration. These are common root canal infection symptoms. A digital X-ray and clinical exam help confirm the need.

A routine root canal usually takes 30–45 minutes. More complex cases may require slightly longer or an additional visit. Patients with simple anatomy may be eligible for a single-sitting RCT.

A single-sitting root canal is when the entire procedure is completed in one appointment. It is suitable for teeth without severe infection or swelling. Our single sitting RCT dentist will assess whether you qualify during your checkup.

Yes, in most cases. A root canal-treated tooth becomes slightly weaker, and a crown helps protect it from fractures and restores full chewing strength. Crowns also improve durability and long-term success.

With proper oral hygiene and a good-quality crown, a root canal-treated tooth can last many years. Regular checkups and cleanings help maintain long-term health.

Delaying treatment allows the infection to spread, leading to increased pain, swelling, bone loss and possible tooth extraction. Early treatment saves the natural tooth and prevents unnecessary complications.
