What happens during a root canal?

The short answer

The dentist removes infected tissue inside the tooth, cleans and seals the canals, then discusses the final restoration. The steps and number of visits depend on the tooth.

What to consider for your own care

The dentist may need to examine the tooth and use appropriate imaging to understand the infection or damage. Ask why the proposed treatment is needed, what alternatives exist, and what recovery and follow-up may involve.

When to speak with a dentist

A rapidly worsening swelling, fever or difficulty swallowing needs urgent medical or dental attention.

Next step

Ask Dental Works: “What happens during a root canal?” Share your symptoms, goals and any deadline so the dentist can explain suitable options and what should happen next at a Sion East consultation.
