Root Canal

A root canal is a common dental procedure used to treat the soft tissue (pulp) inside a tooth when it becomes inflamed or infected due to deep decay, repeated dental work, cracks, or trauma. Symptoms that may indicate the need for a root canal include persistent tooth pain, prolonged sensitivity to hot or cold, swelling or tenderness in nearby gums, and darkening of the tooth, though some infected teeth have little or no pain.

The procedure is usually performed under local anaesthetic and involves removing the diseased pulp, cleaning and disinfecting the canal system, and filling the space with a biocompatible material before sealing the tooth. After a root canal, many teeth will require a crown or other restoration to restore strength and function; recovery is generally quick, with mild discomfort for a few days that can be managed with over-the-counter pain relief, while extraction and replacement (for example with an implant or bridge) remains an alternative if the tooth cannot be saved.
