Root canal treatment (endodontic therapy) is a clinical procedure that removes pulp infection or necrosis to preserve the tooth. Untreated pulp infection can progress and lead to serious clinical complications; seeking assessment at the first signs is therefore advisable.
Regarding pain — a common concern: the procedure is performed under local anaesthesia, so no pain is felt during the treatment. Mild sensitivity for a few days afterwards is normal and expected as part of the healing process.
During treatment, infected or necrotic pulp tissue is removed with specialist instruments, the canal system is cleaned and shaped, then sealed with a biocompatible filling material. The procedure may be completed in a single visit or require multiple sessions depending on the case.
A tooth that has undergone root canal treatment is typically restored with a crown for long-term use. With good oral hygiene and regular check-ups, treated teeth can function for many years.
Spontaneous tooth pain, sensitivity to heat, or gum swelling may indicate a pulp problem. Waiting for such symptoms to resolve on their own without clinical evaluation is not advisable.
