Root canal treatment is necessary mainly because of infections in the root canals
This is generally due to severe caries or cavity of the tooth. Sometimes dental gangrene of the pulp tissue can happen because of an accident involving teeth. In these cases, root canal treatment is also needed.
Infections on the tip of the root canals are most often symptomless. They are often accidentally discovered during an X-ray. A root canal infection will not heal with antibiotics. When the tooth’s nerve-vessel tissue is infected and consequently damaged, the body’s bloodstream is not connected to the root canals. Because microbes are in the root canals, the correct dental treatment is root canal treatment.
