p>Cases where tooth can be retained even though caries were involved with the dental pulp, gross tooth destruction with pulp involvement and good bone support to the pulp involving tooth is the criteria for RCT.

The dentists will decide about the number of sittings. With latest technology and advancement in techniques, root canal in one sitting is done in India. The dentist starts with treating any infections or abscesses with antibiotics. The next step is to anesthetise the tooth for starting the procedure. The next steps in treatment are as follows:

• An x ray of entire tooth called periapical x-ray is taken. Then a rubber damn is placed for isolation of the area
• An opening is made directly above the pulp chamber to give access to it.
• Tiny instruments called files are used to remove diseased tissue and nerve manually or by slow speed rotary instruments
• An x-ray is taken again to determine the root length
• After making sure that the entire nerve is removed so that there is no re-infection or pain, the apex of the root is closed.
• The root canals are then cleaned and dried completely with absorbent paper points.
• Guttapercha points are used to fill and seal the tooth roots
• Any remnant caries are removed and a temporary filling or permanent filling is done.
• A crown is later placed on this RCT tooth since it becomes brittle with time due to lack of blood and nerve supply

There is a possibility of mild pain or discomfort which can be relieved by pain killers. Antibiotics are given to prevent uneventful healing without infections.

Properly done RCT will last a lifetime with a proper crown accompanying it.
