Root canal therapy treats the inside of a tooth when the pulp (nerve) is inflamed, infected, or damaged—often as an alternative to extraction when the tooth can be saved.

Symptoms that may prompt assessment

You might need assessment if you experience:

• Prolonged sensitivity to hot/cold
• Pain on biting
• Swelling or a bad taste (in some cases)
• Deep decay or cracks involving the nerve

Symptoms vary—only an exam can confirm what’s happening.

What treatment aims to do

The goal is to clean and disinfect the root canal system, then seal and restore the tooth—often with a filling and sometimes a crown for protection, depending on the tooth.

Does it hurt?

Many patients worry about pain. Modern techniques and anaesthesia are used to keep you comfortable during treatment. We’ll discuss what to expect for your case.

Aftercare

You may have temporary sensitivity while healing. Follow post-op instructions and attend follow-ups as advised.
