Filling Root Canal
A root canal filling is a way of keeping a tooth, once the live part (the pulp) has become irreversibly damaged.
The pulp is a mixture of nerve fibres and tiny blood vessels that can become very inflamed (giving tooth ache) or die off (causing an abscess). This can happen either in the presence of tooth decay or after a heavy blow to the tooth.
The aim of the procedure is to painlessly remove the damaged pulp, under local anaesthetic, and remove any infection that may be present. Once the canals have been cleaned and shaped they are filled with a special filling material. This work is usually carried out over two visits of up to 90 minutes a time. Once the root canal filling is in place, the crown of the tooth is restored with a large filling or cast restoration.
