Microscopic Root Canal Treatment

A root canal saves a tooth whose inner pulp, the soft tissue holding the nerve and blood supply, has become infected or inflamed. Once that happens the pulp cannot heal on its own. The treatment removes it, cleans and seals the space inside the roots, and lets you keep a tooth that would otherwise have to come out.

At The Tooth Corner this is the clinic’s flagship treatment. Dr. Shabnam holds an MDS in Conservative Dentistry and Endodontics, has completed over 2,919 root canals, and performs every case herself under a dental operating microscope.

Signs your tooth may need one

• Pain that lingers for minutes after something hot or cold, rather than fading in seconds
• Throbbing that arrives on its own, often worst at night when you lie down
• Pain when you bite or press on the tooth
• A swelling on the gum near the tooth, or a small pimple that comes and goes
• A tooth that has turned grey or darker than its neighbours
• Sometimes nothing at all, and a dead pulp is found on a routine X-ray

If a tooth is keeping you awake right now, our guide on tooth pain at night covers what genuinely helps until morning and what to avoid.

Why the microscope matters more than it sounds

Most root canals that fail do not fail because of the dentist’s care on the day. They fail because a canal was missed.

Molars commonly have three canals, often four, and the fourth is narrow, hidden and easy to walk past with the naked eye. Leave it untreated and the infection stays inside the tooth, sealed in. The tooth may feel fine for a year or two, then flare up, and by then the options are re-treatment or extraction.

A dental operating microscope magnifies the inside of the tooth many times over. It is how extra canals, curved roots, hairline cracks and leftover infection actually get seen. It also means less healthy tooth structure has to be removed to find them, which leaves the tooth stronger afterwards.

What happens, in short

The tooth is numbed, a rubber dam isolates it so nothing touches your tongue, a small opening is made, and each canal is cleaned, shaped and disinfected before being sealed. Most patients are surprised at how ordinary it feels.

For the full step by step version, including what the days afterwards feel like, read our guide on what actually happens in a root canal.

Re-treatment: when a root canal has already failed

A good number of the cases we see were treated somewhere else and did not settle. The tooth aches on biting, or a swelling keeps returning, or an X-ray shows infection still sitting at the root tip.

Re-treatment means reopening the tooth, removing the old filling material, locating what was missed and sealing the tooth properly. It is harder than a first-time root canal and it is precisely the work specialist training and magnification exist for. If you have X-rays or notes from the earlier treatment, bring them, since they often show exactly where the problem is.

When we will tell you not to do it

Not every painful tooth is worth saving, and you should be suspicious of a clinic that never says so. A root canal is the wrong call when the tooth is cracked vertically down the root, when too little tooth structure remains above the gum to hold a crown, or when the supporting bone has already been lost to advanced gum disease.

In those cases the honest answer is removal, followed by a bridge or a dental implant. You will hear that from us directly rather than after you have paid for treatment that was never going to hold.

What it costs

Treatment	Typical Bangalore range
Front tooth root canal	₹4,000 to ₹7,000
Molar root canal	₹6,000 to ₹12,000
Re-treatment of a failed root canal	₹8,000 to ₹15,000
Crown afterwards	₹3,500 to ₹15,000

These are indicative ranges to help you plan, not a price list. Your exact figure depends on which tooth it is and how complex the canals are, and it is confirmed in writing before treatment begins. The quote covers the complete treatment rather than each sitting, so extra visits do not mean extra charges. Our root canal cost guide explains what moves the number, and the crown cost guide covers the cap that follows.

Be wary of teaser pricing. A root canal advertised at ₹1,999 usually covers only the first sitting, with the rest billed as you go.

Finishing the job: the crown

A root canal treated back tooth is hollow and brittle, and it will crack under chewing pressure without a crown over it. A cracked root canal tooth is usually beyond saving, so skipping the crown risks losing the tooth you just paid to keep.

This is the most common reason treated teeth are lost, and it is entirely avoidable. See crowns and bridges for the materials and how the fitting works.
