ROOT CANAL THERAPY
WHAT IS A ROOT CANAL?
Root canal therapy is the process of removing the “pulp” of a tooth. The pulp is comprised of nerves, blood vessels and other living tissue. When it has become so damaged or infected that leaving it would result in the loss of the tooth and a more serious, systemic infection.
The patient is first numbed using a local anesthetic.
Access to the pulp is achieved by creating a small hole in the crown of the tooth, and the infected tissue is then cleared out using a series of drills and files.
Afterwards, the hollows of the tooth are cleaned and decontaminated.
A series of files, gradually increasing in size, are used to widen and shape these canals to prepare them for restoration.
This part of the process can take multiple appointments, as the dentist needs time to ensure that the infection does not return after removal.
