Under what circumstances does a tooth require root canal treatment?

Root canal treatment is typically performed in the following situations: 1. Traumatized teeth: When a tooth sustains injury resulting in crown fracture, pulp exposure, or similar conditions, root canal treatment is required to preserve the tooth and repair the damage. 2. Pulpal diseases: If a tooth develops pulpitis, pulp necrosis, internal resorption, or pulp calcification—conditions in which the pulp cannot be preserved—root canal treatment becomes necessary. This is because inflammation of the pulp cannot be resolved by the body's immune system alone, and the pulp tissue along with bacteria and secretions inside must be removed through medical intervention. 3. Periapical diseases: In cases of periapical inflammation (apical periodontitis), root canal treatment can effectively eliminate the inflammation at the root tip, preventing tooth extraction or further deterioration and eventual collapse of the affected tooth. If you have any concerns, please consult a dental professional.
