Even if root canal treatment is successful, the long-term health of the tooth must be supported by regular care and proper restoration. Because the tooth is vulnerable to fracture after root canal treatment, it must be strengthened with a filling or crown. Furthermore, poor oral hygiene, intense chewing forces, or trauma can reinfect a root canal-treated tooth. Regular dental checkups, fluoride applications, and healthy eating habits prolong the life of the tooth and reduce the risk of infection.
