The phrase "root canal" has an undeserved reputation — one built on stories from a much earlier era of dentistry. Today, a root canal performed by a specialist is no more painful than getting a routine filling. What is painful is the infected tooth that makes it necessary. If you are searching for a trusted root canal dentist in Rajshahi, this guide walks you through every stage of a specialist procedure.
What Is Root Canal Treatment?
Every tooth has a soft inner core called the pulp — a network of nerves, blood vessels, and connective tissue. When bacteria reach this layer through deep decay, a crack, or trauma, the pulp becomes infected and inflamed. Left untreated, the infection spreads to surrounding bone, causes a dental abscess, and ultimately costs you the tooth.
Root canal treatment (endodontic treatment) removes the infected pulp, cleans and seals the empty canals, and saves the tooth. Without it, the only alternative is extraction — and keeping your natural tooth is almost always the better outcome for your bite, bone, and long-term oral health.
Signs You May Need Root Canal Treatment
Book a root canal specialist consultation in Rajshahi if you notice:
- Severe, persistent toothache — especially when biting or applying pressure
- Prolonged sensitivity to heat or cold that lingers after the source is removed
- Darkening or discolouration of the tooth
- Swelling or tenderness in the nearby gum
- A recurring pimple-like bump on the gum — a dental fistula, sign of active infection
The Root Canal Procedure: Step by Step
Examination & X-ray
Dr. Kamrul Hridoy examines the tooth and takes a dental X-ray to assess the infection, root canal shape, and surrounding bone. This gives a complete picture before treatment begins and determines how many appointments you will need.
Local Anaesthesia
The area around the tooth is numbed completely with local anaesthetic. You will feel pressure during the procedure — but not pain. If you have had difficult experiences with dental injections before, let the team know; there are ways to ensure full numbness before any work begins.
Removing the Infected Pulp
A small opening is made in the crown of the tooth. Using precision endodontic instruments, the infected pulp tissue is carefully removed from each root canal. The canals are then measured to their exact length — critical for thorough cleaning without over-extension.
Cleaning, Shaping & Sealing the Canals
The empty canals are shaped with fine files and flushed with an antimicrobial solution to eliminate bacteria throughout their full length. Once clean and dry, they are filled with gutta-percha — a biocompatible rubber material — and sealed with dental cement to prevent re-infection. This step requires the specialist training in conservative dentistry and endodontics that Dr. Hridoy holds.
Crown or Permanent Restoration
After root canal treatment the tooth is more brittle. A dental crown is usually recommended to protect it from cracking under normal bite pressure. Dr. Hridoy advises whether a crown or a strong filling is appropriate based on how much natural tooth structure remains.
Does Root Canal Treatment Hurt?
The infection hurts. The treatment relieves it.
Once local anaesthetic is administered, patients feel pressure and movement — not the sharp pain they feared. Mild soreness for 2–3 days after is normal as surrounding tissue settles; standard Paracetamol or Ibuprofen manages it well. Most patients return to normal activities the following day.

How Many Visits Does It Take?
Front teeth with 1–2 canals are typically finished in a single appointment. Molars with 3–4 canals may need a second visit. If there is an active abscess, a short antibiotic course may be prescribed first to bring the infection down.
Why See a Root Canal Specialist in Rajshahi?
Curved canals, calcified canals, or re-treatment of a previously filled canal demands a level of precision beyond general dentistry. These cases often require specialist referral in a general practice setting.
