Root Canal Treatment
Stop the pain, save the tooth — modern, near-painless root canal therapy in a single comfortable visit whenever possible.
What Is Root Canal Treatment (RCT)?
Root canal treatment (RCT) removes infected or inflamed tissue from inside a tooth — the pulp — cleans and disinfects the space, then seals it so the tooth can keep doing its job without pain. It’s the procedure that saves a tooth once decay or a crack has reached the nerve, and it’s usually the alternative to extraction.
At Apurva Dental Care, root canal therapy is performed under local anaesthesia with rotary instrumentation and, for complex or re-treatment cases, microscopic magnification led by Dr. Ruchi Lohia. Most single-rooted teeth are completed in one sitting; molars with multiple canals may need two visits.
- Removes the source of tooth pain, often within one visit
- Saves your natural tooth instead of extracting it
- Stops infection from spreading to the jawbone
- Preserves your natural bite and facial structure
- Modern rotary technique means significantly less discomfort than older methods
Signs You May Need Root Canal Treatment
- Sharp or lingering pain when biting or with hot/cold
- A tooth with deep decay reaching the nerve
- A cracked or chipped tooth exposing the inner pulp
- Swelling or a small bump on the gum near a tooth

What Happens, Step by Step
Diagnosis & X-ray
A digital X-ray (or OPG) confirms the extent of infection and maps the canal structure before any treatment starts.
Local Anaesthesia
The tooth and surrounding gum are fully numbed — most patients feel pressure at most, not pain.
Cleaning the Canals
Infected pulp tissue is removed and each root canal is cleaned, shaped and disinfected.
Sealing the Tooth
The cleaned canals are filled with a biocompatible material to prevent re-infection.
Crown Placement
A crown is usually recommended afterward to protect the treated tooth from fracture during chewing.
Common Questions About Root Canal Treatment
Modern RCT is performed under local anaesthesia, so the procedure itself is not painful. Mild sensitivity for a day or two afterward is normal and manageable with over-the-counter pain relief.
Most single-rooted teeth (front teeth) are completed in one sitting. Molars with multiple canals, or teeth being re-treated, may need two appointments.
In most cases, yes — a root-canal-treated tooth loses some structural strength and becomes more brittle, so a crown protects it from cracking under normal biting force.
Untreated infection can spread to the surrounding bone, cause an abscess, and eventually mean the tooth cannot be saved at all.
Instead of only searching for the best dentist clinic in Kolkata, check experience, X-ray use, pain control, crown planning, reviews, and explanation style. Apurva Dental Care fits decision-stage consultations well. This keeps expectations more realistic.
Night pain can mean the tooth problem has reached deeper areas. Book a dental visit soon, especially if painkillers give only temporary relief or swelling starts. This helps protect long-term results.
Modern root canal treatment is usually done with numbing, so pain is controlled. You may feel pressure or mild soreness later, but sharp pain should be reviewed. It also makes follow-up easier.
If the tooth can be saved, the root canal may protect chewing and avoid replacement costs later. Removal is considered when the tooth is too damaged to restore. That makes decision-making easier.
Many patients return to work after a simple sitting. If infection was severe or the appointment was long, soft food and rest may feel better that day. This reduces rushed treatment decisions.
