Root canal therapy involves removing infected or inflamed dental pulp to preserve the tooth. This treatment becomes necessary when the pulp—containing the tooth’s blood and nerve supply—has been compromised by decay or injury.

Early symptoms often include sensitivity to hot, cold, or sweet foods. As the nerve becomes increasingly irritated, swelling, throbbing pain, and inflammation may develop. If untreated, an abscess can form, and the tooth may ultimately require extraction.

During treatment, the root canal is meticulously cleaned and sealed to prevent reinfection. This may be completed over one or more appointments. A crown is often recommended afterwards to strengthen and protect the tooth.
