A healthy tooth consists of a crown (the part inside the mouth) and one or more roots. Inside the tooth, there is a tissue called pulp, which consists of blood vessels and nerves, and it provides nourishment to the tooth. The nerve tissue inside the tooth may become damaged, infected, or inflamed due to decay, gum disease, or trauma. Symptoms of this condition may include pain, swelling, or it can be completely asymptomatic. Root canal treatment is a procedure performed to save teeth with infected or damaged nerve tissue, restoring them to health. This involves removing the nerve tissue and filling the empty space with canal filling materials to make the tooth healthy. The process involves removing decay and other disease-causing agents mechanically and chemically, cleaning the space thoroughly up to the root tip, and then filling the entire space with canal filling materials.
The cavity is opened to clean the decay and remove the pulp.
The canals in the roots are cleaned mechanically and chemically.
The root canals are filled, and the tooth is restored.
