Quick Answer: A root canal (RCT) saves a badly infected tooth by removing the infected pulp, disinfecting the canals, and sealing the tooth. Modern RCT is virtually painless, often done in a single visit, and almost always better than extraction because it keeps your natural tooth. A crown is usually placed afterwards to protect it.
Most patients who walk into my clinic for a root canal arrive with two emotions: pain, and dread about the procedure itself. After years of treating root canals in Nagpur, I can tell you the dread is almost always worse than the treatment. This guide is what I explain to my own patients — the real signs, the process, recovery, and how to think about cost — so you can decide calmly.
What a Root Canal Actually Does
Inside every tooth is soft tissue called pulp, containing the nerve and blood supply. When deep decay, a crack, or repeated dental work lets bacteria reach the pulp, it becomes infected.
A root canal removes that infected pulp, cleans and shapes the inner canals, and seals them. Your natural tooth stays — only the diseased tissue inside is removed. That is why I almost always recommend saving the tooth over pulling it: nothing replaces a natural tooth as well as the tooth itself.
Signs You May Need a Root Canal
Book an examination if you notice:
- Persistent toothache, especially pain that throbs or wakes you at night.
- Sensitivity to hot or cold that lingers for several seconds after the source is gone.
- Pain when biting or chewing on one particular tooth.
- Swelling or a small ‘pimple’ on the gum near the tooth.
- A tooth darkening compared to its neighbours, or a cracked tooth after injury.
The Procedure, Step by Step
- Examination and digital X-ray to confirm the infection and map the canals.
- Local anaesthesia — the tooth and area are fully numbed.
- Cleaning and shaping the canals with fine rotary instruments.
- Filling and sealing the disinfected canals.
- Restoring the tooth, usually with a crown.
Many straightforward cases are completed in a single sitting of about 45–90 minutes. Severely infected or complex teeth may need a second visit to let the canal settle and heal fully.
“Will It Hurt?” — An Honest Answer
This is the question I hear most. Honestly: a modern root canal feels much like getting a filling. The pain people fear is the pain of the infection — and the treatment relieves it. With proper anaesthesia, most patients are surprised how easy it is. Expect mild soreness for a day or two afterwards, managed with standard pain relief.
Why You Usually Need a Crown Afterwards
A root-canal-treated tooth can become brittle over time because its internal blood supply is gone. A crown caps and protects it, restores full chewing strength, and helps it last for years. We handle the root canal and crown under one roof so your care stays coordinated.
Root Canal vs. Extraction
Patients sometimes ask whether it is simpler to just remove the tooth. In most cases, no. Saving the natural tooth preserves your bite, stops neighbouring teeth drifting, and avoids the greater long-term cost and complexity of an implant or bridge later. Extraction is reserved for teeth too damaged to save.
What About Cost?
The cost of a root canal depends on which tooth is involved (molars have more canals than front teeth), the complexity of the infection, and whether a crown is needed. Rather than quote a misleading figure, I prefer to examine the tooth and give you a clear, upfront estimate at your consultation — with no hidden charges, so you know exactly what is involved before deciding.
Recovery and Aftercare
- Avoid chewing on the treated side until numbness wears off and the final restoration is placed.
- Use recommended pain relief for the first day or two.
- Keep brushing and flossing gently but thoroughly.
- Return promptly for your crown to protect the tooth.
- Call us if you get severe pain, swelling, or an uneven bite.
