Root canal treatment is a procedure that involves cleaning and disinfecting the infected or damaged nerves and blood vessels inside the tooth, and then filling the space with a special material. This treatment aims to save the tooth rather than extract it and is usually performed in cases of deep cavities, trauma, or infections within the tooth.

During the procedure, the dentist numbs the affected area and cleans the root canal inside the tooth. The canal is then thoroughly disinfected and filled with a sealing material. The treatment is generally painless due to the local anesthesia used. After the procedure, some mild sensitivity may occur, but it typically resolves in a few days.

Once the root canal treatment is successfully completed, the tooth can continue to function normally for many years. However, it is often recommended to place a crown over the tooth to protect it and prevent future fractures, ensuring the long-term health and stability of the tooth.
