About Endodontics
What is Endodontics?
Endodontics is the branch of dentistry that deals with the inside of the tooth — specifically the dental pulp (the soft tissue containing the nerves and blood vessels) and the roots that anchor your tooth to the jaw. When the pulp becomes infected or inflamed from deep decay, a crack, or an injury, endodontic treatment saves the tooth instead of removing it.
The most common endodontic procedure is root canal treatment (RCT). During an RCT, the infected pulp is removed, the narrow canals inside the root are cleaned and disinfected, and the tooth is sealed — so your natural tooth stays firmly in place and the pain disappears. Losing a natural tooth sets off a chain of problems: neighbouring teeth drift, the bite changes, and the jawbone shrinks. Saving the tooth avoids all of that.
Modern endodontics — using rotary instruments, effective local anaesthesia and 3D imaging when needed — makes root canals typically painless and often completable in a single sitting, with long-term success rates above 95%. At Divine Dental & Aesthetics in Sector 137, Noida, every endodontic case is carried out personally by Dr. Reena (BDS).
Warning Signs
When You Might Need a Root Canal
Tooth pain is never normal. These are the warning signs that the pulp inside your tooth may be infected — and that it's time to see us.
Severe, Lingering Tooth Pain
Pain that throbs continuously, wakes you at night, or lingers for more than a few seconds after hot or cold food is a classic sign the pulp is inflamed or infected. Don't wait for it to "settle" — early treatment is simpler and saves the tooth.
Sensitivity to Hot or Cold
Sharp sensitivity to hot drinks, cold food or even air — especially when it lingers 30 seconds or more after the trigger — usually means the nerve inside the tooth needs attention, not just a sensitive-teeth toothpaste.
Swelling or a Gum Pimple
A bump or pimple on the gum near a tooth, facial swelling, or a persistent bad taste points to an abscess — an infection draining from the tooth root. This needs urgent treatment before it spreads.
A Darkened or Discoloured Tooth
A single tooth that turns grey, dark yellow or brown — often months or years after a knock or injury — usually means the pulp inside has died. A root canal can still save the tooth.
After Tooth Trauma or a Crack
A fall, sports knock, or biting something hard can crack a tooth and expose the pulp to infection. A same-day evaluation gives the tooth the best chance of being saved.
A Failed Previous Root Canal
If an old root canal has become painful again or the infection has returned, endodontic retreatment (Re-RCT) can clean and reseal the tooth — often avoiding extraction.
The Process
How Long a Root Canal Takes at Divine Dental
Most root canals are completed in a single sitting of 60–90 minutes. Here's exactly what happens at each stage.
01
Diagnosis & Imaging
15–20 minutes
Clinical examination and a digital X-ray (with a 3D CBCT scan for complex cases) to see the tooth's internal anatomy and confirm the diagnosis. We explain the plan and cost before starting anything.
02
Painless Local Anaesthesia
5-10 minutes
A topical numbing gel is applied first, followed by local anaesthetic — so you barely feel the injection, and within a few minutes the tooth is completely numb. Comfort comes first.
03
Cleaning the Canals (Rotary Endodontics)
30–45 minutes
A small access opening is made in the tooth. Using rotary instruments and irrigation, we remove the infected pulp, clean and shape the canals, and disinfect the entire root system thoroughly.
04
Filling & Sealing
15–20 minutes
Once the canals are clean and dry, they're filled with a biocompatible material (gutta-percha) and permanently sealed. A temporary filling closes the access opening.
05
Crown Placement (usually a separate visit)
1–2 visits over 1–2 weeks
A crown protects the treated tooth from fracture, since a root-canal-treated tooth becomes more brittle. We strongly recommend a crown for back teeth that take heavy chewing force.
