A root canal treatment is used to repair and save a tooth that is badly decayed or becomes infected or when an injury or a large cavity damages the tooth’s root. During a root canal procedure, the nerve and pulp are removed and the inside of the tooth is cleaned and sealed. Without treatment, the tissue surrounding the tooth will become infected and abscess may form.
Material used to fill the root canal: Root canal filling material (gutta percha) is placed in the canals and the tooth is sealed with a temporary filling to protect it from contamination. Then a crown is usually placed over the tooth to seal and protect it from recontamination and future damage.
The tooth area is made numb by using anaesthesia and an opening is made through the enamel and dentin to reach the pulp
The depth of the root canal is determined.
The infected pulp is removed. The canal is cleaned, enlarged and shaped.
The canal is filled and sealed. A metal post may be added for structural support or to retain restorative materials.
The tooth is sealed with a temporary filling. A crown is then added to protect the natural tooth.
