The tooth has mainly two parts which are the crown and the root. Root is the part below the gum line which is not visible. Root is supported by bone and sealed by strong healthy gums. Endodontic therapy or root canal treatment is a treatment for the infected pulp of a tooth which is intended to eliminate infection and keep the tooth healthy.
Bacteria and food remains will combine to cause tooth decay. A sticky substance called plaque, is formed on your teeth as well as around your gums. The plaque contains bacteria that feed on the sugars in the food you intake to release acids.
