Root Canal Treatment in Chennai: Painless RCT Explained

What is a root canal treatment (RCT)?

A root canal treatment removes the infected or damaged pulp (nerve) from inside a tooth, cleans and disinfects the canals, and seals them. It saves a badly decayed or infected tooth that would otherwise need to be extracted — letting you keep your natural tooth instead of replacing it.

Signs you may need a root canal

• Persistent or throbbing toothache.
• Lingering sensitivity to hot or cold.
• Swelling or tenderness in the gums near a tooth.
• A darkening or discoloured tooth.
• A pimple-like bump on the gum (abscess).

What affects the cost of a root canal?

Rather than a fixed price, root canal cost depends on several factors your dentist will explain during consultation:

• Which tooth — back molars have more canals than front teeth, so they take more time.
• Level of infection — heavily infected teeth may need extra sittings.
• Re-treatment — redoing a previous root canal is more complex.
• Crown afterwards — most treated teeth need a protective crown.

For an exact, personalised estimate, book a consultation at Illume Advanced Dentistry, Nungambakkam — you will get a clear treatment plan after a quick examination and X-ray.

Does a root canal hurt?

No — this is the biggest myth in dentistry. Modern root canal treatment is done under local anaesthesia and is no more uncomfortable than a routine filling. In fact, RCT relieves the severe toothache caused by the infection. At Illume Advanced Dentistry we offer painless, single-sitting root canals where suitable, using rotary instruments for faster, gentler treatment.

Do I need a crown after a root canal?

Usually yes, especially for back teeth. After RCT a tooth becomes more brittle, and a crown protects it from cracking. Front teeth may sometimes be restored with a filling instead. Your dentist will advise based on the tooth's strength.

What happens if you delay a root canal?

Delaying allows the infection to spread, which can cause an abscess, swelling, bone loss and eventually tooth extraction. Treating early saves the tooth — so book as soon as you notice persistent toothache, sensitivity to hot/cold, or swelling.

Frequently asked questions

Is root canal treatment painful?

No. It is done under local anaesthesia and is virtually painless. It actually relieves the toothache caused by the infection.

How many sittings does a root canal take?

Many root canals can be completed in a single sitting. Complex or infected cases may need two visits.

Can a root canal tooth last a lifetime?

Yes. With a protective crown and good oral hygiene, a root-canal-treated tooth can last many years, often a lifetime.

Is it better to extract or do a root canal?

Saving the natural tooth with a root canal is almost always better than extraction, as it preserves chewing function and prevents neighbouring teeth from shifting.

Do I need a crown after RCT?

Usually yes, especially for back teeth, as a crown protects the treated tooth from cracking.
