Root Canal Treatment (RCT) in Parnasree, Behala, Kolkata

A root canal is the treatment that lets you keep a tooth that would otherwise have to come out. Dr. Nabanita Chaklader has a declared special interest in endodontics, and RCT is the single most requested treatment at ORADENT.

When you need a root canal

Inside every tooth is a soft core of nerve and blood vessels called the pulp. When deep decay, a crack or an old leaking filling lets bacteria reach that pulp, it becomes inflamed and then infected. The pain is characteristic: it lingers after something hot or cold, it worsens when you lie down at night, and eventually the tooth becomes tender to bite on.

Left alone, the infection travels out of the root tip into the surrounding bone and forms an abscess. At that point the choice narrows to a root canal or an extraction. Coming in early is what keeps the tooth.

Some teeth need a root canal without ever hurting much — the nerve has already died quietly. That is why we take an X-ray of any tooth with a deep cavity, a darkened shade, or a history of trauma.

What happens during treatment

The tooth is numbed thoroughly with local anaesthetic — a modern root canal should feel no different from having a filling done. Most patients tell us afterwards that the anticipation was worse than the appointment.

A small opening is made in the crown of the tooth, the infected pulp is removed, and the root canals are cleaned and shaped along their whole length. The canals are disinfected, dried, and sealed with an inert filling material so bacteria cannot recolonise them. The access opening is then restored.

Straightforward front teeth are often completed in a single sitting. Molars, badly infected teeth, or teeth with curved canals are usually done across two visits, with a medicated dressing in between to settle the infection.

The crown afterwards matters

A root-treated back tooth has lost its blood supply and a good deal of its structure, which makes it brittle. Placing a crown over it after treatment is not an upsell — it is the difference between a tooth that lasts decades and one that splits within a couple of years.

We will tell you plainly whether your tooth needs a crown or whether a well-built filling will do, and what each option costs, before any work starts.

Recovery and aftercare

Mild tenderness for two or three days is normal and settles with ordinary painkillers. Avoid chewing hard food on that side until the permanent restoration is fitted.

Call us if pain increases after the third day, if swelling appears, or if a temporary filling comes out — all three are easy to sort out quickly and difficult to sort out late.
