root canal treatmentA root canal is the space within the root of a tooth. It is part of a naturally occurring space within a tooth that consists of nerve tissue and blood vessels that supply pulp of the tooth. If decay from cavities reaches the dental pulp, a root canal is required.

Endodontic therapy is a sequence of treatment for the pulp of a tooth which results in the elimination of infection and protection of the decontaminated tooth from future microbial invasion.

Endodontic therapy involves the removal of the contaminated necrotic structures, shaping, cleaning and decontamination of the canals and obturation (filling) the canals.

After endodontic treatment the tooth will be dead, but tooth can be restored to function.
