What is a root canal and when do you need one?
A root canal (RCT) is a tooth-saving procedure performed when the soft pulp tissue inside a tooth becomes infected, inflamed or damaged — usually due to deep decay, a cracked tooth, repeated dental procedures or trauma. Without treatment, the infection spreads to the bone, eventually causing severe pain, swelling and tooth loss.
Common signs you may need a root canal include: persistent toothache, sharp pain when biting, prolonged sensitivity to hot or cold, swollen or tender gums around a single tooth, a darkened tooth, or a small pimple-like bump on the gum.
Why patients choose Smilz for root canal treatment in Kolkata
Dr. Dibyendu Dutta has performed thousands of root canals over 25+ years. We use rotary NiTi files, electronic apex locators and modern obturation systems to make the procedure faster, more accurate and dramatically more comfortable than traditional hand-instrumentation. Our anaesthesia protocols ensure that the procedure itself is virtually painless — most patients are surprised at how easy it feels.
How much does a root canal cost in Kolkata?
Root canal treatment cost in Kolkata varies based on which tooth is involved (front teeth have one canal, molars have three or four), the complexity of the canals, and whether a crown is required afterward. At Smilz, single-sitting root canals typically range from ₹4,500 to ₹8,500, with porcelain crowns from ₹5,000 onwards. We always provide a transparent written estimate before starting.
What to expect — single-sitting root canal in 60–90 minutes
After local anaesthesia, the infected pulp is gently removed, the canals are cleaned, shaped and disinfected, then sealed with a biocompatible filling. The tooth is then prepared for a crown to protect it long-term. Most patients return to normal eating within a few hours and report no significant pain.
