Root Canal or Extraction and Implant: Which Is the Better Plan?

The dentist is asking three things. Is there enough sound tooth above the gum to hold a crown? Is the root intact, with no vertical crack? Is the supporting bone and gum healthy enough? If the answer to all three is yes, the tooth can usually be saved.

If the root is split lengthways, or the tooth has broken below the bone, or gum disease has destroyed most of its support, a root canal will not give a lasting result. In those cases, extraction is the honest recommendation and a root canal first would be money wasted.

A natural tooth stays connected to the jaw through its ligament, which senses bite force and keeps the bone around it working. Neither an implant nor a bridge can reproduce this fully.

The treatment is shorter. A root canal and crown can be done in a few weeks, against three to six months for an implant to heal, and there is no surgery. It is also cheaper. A root canal and crown together typically total ₹10,000 to ₹25,000 in Lucknow in 2026, while extraction and an implant run ₹25,000 to ₹60,000, as set out on our root canal cost in Lucknow page.

The root canal route also keeps the implant option open. A tooth that fails later can still be extracted and replaced, usually without having closed any doors.

A tooth with a poor long-term outlook is better replaced than repeatedly repaired. Repeated re-treatments, a crown on a tooth with very little structure, and a tooth with a root fracture all fall into this group.

An implant also avoids the tooth fracture and reinfection risks that follow a root-treated tooth. It does not decay, though the gum and bone around it can still develop infection if it is not cleaned. The implant route is explained on our dental implants page, and a related decision between replacement options is in dental implant vs bridge.

Sometimes the plan is a mix. A root canal is attempted where the tooth has a fair chance, with an honest conversation beforehand about what happens if it fails.

Ask the dentist what remains of the tooth, whether the root is cracked, how the gum and bone look on the X-ray, and what the plan is if the tooth fails. A good answer states the realistic odds and the next step, not a promise.

Ask for the complete cost of both routes, including the crown on the root canal route and the crown, abutment and any bone graft on the implant route. Our root canal treatment page explains the first route. When the tooth needs a crown, the steps are in what happens when you get a crown (cap).
