Patients often face a tough choice. Whether to remove the tooth causing the pain or to try and preserve it. When facing such a dilemma we need to remember that the extraction is an irreversible procedure and can cause problems in their masticatory apparatus later. Endodontics help with this decision by preserving the tooth and treating the cause of the pain. Endodontic treatment is used for treating inflammation, necrosis and gangrene of the tooth by removing or treating the infected dental pulp inside the tooth.
