Mention “root canal” at a family dinner in Kolkata and someone will wince. Most of that fear comes from stories that are twenty years old. Modern RCT teeth treatment feels closer to getting a deep filling than the ordeal people imagine, and in many cases it is the only thing standing between you and losing a natural tooth.
This guide covers what the treatment involves, why dentists recommend it, and what actually happens in the chair, sitting by sitting.
What Is RCT Treatment?
RCT stands for root canal treatment. It is a dental procedure that removes infected or inflamed tissue from inside a tooth, cleans and disinfects the hollow channels in its roots, and seals them so the tooth can stay in your mouth and keep working normally.
What Is RCT in Teeth, Anatomically Speaking?
To understand what is RCT in teeth, picture a tooth in three layers. On the outside is hard white enamel. Beneath it sits dentin, which is slightly softer and yellowish. At the very centre is the dental pulp, a soft bundle of nerves, blood vessels and connective tissue.
The pulp runs down through narrow passages inside the roots. Those passages are the root canals. A front tooth usually has one canal, while a molar can have three or four, some of them curved and thinner than a hair.
RCT teeth treatment works only on that inner core. The outer structure of the tooth stays in place.
Why RCT Is Done
Put simply, why RCT is done comes down to one fact: once the pulp is badly damaged or infected, it cannot heal on its own. Inflammation of the pulp, called pulpitis, often starts reversible, but past a certain point the tissue begins to die.
Common reasons a dentist recommends the procedure include:
- Deep decay that has worked its way through the dentin and reached the pulp
- A cracked or chipped tooth that exposes the nerve
- An injury from a fall or a knock during sports, even when the tooth looks fine from outside
- A tooth that has already had several large fillings over the years
- A dental abscess, which is a pocket of pus that forms at the root tip
Left alone, the infection can spread into the jawbone and surrounding tissue. The usual alternative to RCT teeth treatment is extraction, followed by an implant or bridge to fill the gap. That route typically costs more, takes longer, and replaces something your body made with something a lab made.
Signs You Might Need a Root Canal
Some symptoms are hard to ignore. Others are easy to brush off until they get worse. Watch for these:
- Sensitivity to hot or cold that lingers for several seconds after you stop eating or drinking
- Sharp pain when you bite down or chew
- A throbbing ache that wakes you up at night
- Swollen, tender gums near one tooth, sometimes with a small pimple-like bump
- A tooth that has turned grey or darker than its neighbours
Not every infected tooth hurts, though. Some are found only on an X-ray during a routine visit. If anything above sounds familiar, an examination with a root canal specialist in Park Street can confirm whether the pulp can be saved.
The RCT Procedure, Sitting by Sitting
The RCT procedure is usually completed in one to three sittings. The number depends on how severe the infection is, how many canals the tooth has, and how the tooth responds after the first round of cleaning.
First Sitting, Diagnosis and Cleaning
Your dentist begins with an X-ray to study the shape and number of canals. The area is then numbed with local anaesthetic, and a thin rubber sheet called a dental dam is placed around the tooth to keep it dry and free from saliva.
A small opening is made on the top of the tooth. Through it, the infected pulp is removed, the length of each canal is measured, and the canals are shaped with fine instruments. They are flushed with disinfecting solutions, a medicated paste is placed inside, and the opening is closed with a temporary filling.
This first visit of RCT teeth treatment generally takes 45 minutes to an hour. Mild soreness for a day or two afterward is normal.
Second Sitting, Disinfection and Sealing the Canals
Once the infection has settled, the temporary filling comes out and the canals are cleaned once more. They are then dried and filled with gutta-percha, a rubber-like material, along with a sealing cement. This permanently closes the space where the pulp used to be, so bacteria have nowhere to return to.
Most patients find this sitting surprisingly uneventful.
Third Sitting, Placing the Crown
A tooth without pulp becomes more brittle over time, especially a back tooth that handles heavy chewing. That is why most dentists recommend a dental crown after the canals are sealed. The tooth is shaped, a scan or impression is taken, and the final crown is fixed once it is ready.
Skipping this step is one of the most common reasons a treated molar cracks later.
Can RCT Be Finished in One Sitting?
Yes, in the right cases. When there is no active infection or swelling and the canals are straightforward, single-visit RCT is possible. Your dentist will decide based on the X-ray and how the tooth looks once opened.
Does RCT Teeth Treatment Hurt?
Far less than most people expect. The entire RCT teeth treatment is done under local anaesthesia, so patients usually feel pressure rather than pain. In fact, the severe toothache that brings people in is caused by the infection, and the treatment is what relieves it.
Aftercare That Protects Your Treated Tooth
A few habits make a real difference in the weeks after treatment. Avoid chewing hard food on that side until your crown is fitted. Finish any medicines your dentist prescribes, even if you feel better early. Keep brushing and flossing normally, and call the clinic if swelling increases instead of settling.
How Long Does a Root Canal Treated Tooth Last?
With a well-fitted crown and good oral hygiene, a treated tooth can last for many years, often a lifetime. If the tooth has darkened, or if you have other chips and gaps you want corrected, the crown stage is a good moment to consider a smile makeover treatment in Park Street so everything matches.

Frequently Asked Questions
How many sittings does RCT take?
Most cases need one to three sittings. Teeth with active infection or multiple curved canals usually take longer than a simple front tooth.
Is RCT teeth treatment painful?
It is done under local anaesthesia, so most people feel only pressure. Some tenderness for a day or two afterward is common and settles with prescribed medication.
Can I eat after the RCT procedure?
Wait until the numbness wears off, which takes a few hours. Stick to soft food and chew on the other side until your permanent crown is in place.
Why RCT is done instead of just removing the tooth?
Keeping your natural tooth preserves your bite, protects the jawbone, and avoids the cost and time of an implant or bridge.
Is a crown necessary after RCT?
For back teeth, almost always, because they take heavy chewing force. Front teeth sometimes manage with a filling alone, depending on how much structure remains.
What does RCT cost in Kolkata?
It varies with the tooth, the number of canals, and the crown material you choose. A consultation and X-ray give you an exact estimate.
