Is root canal treatment painful?

No. With today’s anaesthetics and technology, the procedure is usually painless. Most patients say it feels no worse than getting a regular filling—and it relieves pain, not causes it.

How do I know if I need a root canal?

Common signs include ongoing pain, swelling, temperature sensitivity, discolouration of a single tooth, or a pimple-like bump on the gums. X-rays confirm if the nerve is infected.

What happens if I delay a root canal?

Waiting can allow infection to spread, which increases pain and may lead to tooth loss, bone damage, or systemic complications. Early treatment is key to saving the tooth.

Do I need a crown after a root canal?

Usually, yes—especially for molars or teeth under stress. A crown protects the treated tooth from fractures and restores full strength for chewing and function.

Can a root canal fail or need retreatment?

Yes, but it’s rare. Failures may occur if canals were missed, sealed improperly, or reinfected. In such cases, retreatment or minor surgery may successfully resolve the issue.
