Endodontics deals with the tissues surrounding the root of a tooth.
When nerve tissue or pulp is damaged, it breaks down and bacteria begin to multiply within the pulp chamber. The bacteria and other decayed debris can cause an infection or abscessed tooth. An abscess is a pus-filled pocket that forms at the end of the roots of the tooth. An abscess occurs when the infection spreads all the way past the ends of the roots of the tooth.
Root canal treatment is carried out to remove the built up decay. It involves subsequent cleaning, shaping and decontamination of the hollows within a tooth that are naturally inhabited by nerve tissue and blood vessels.
This procedure is relatively painless when performed properly by an experienced dental surgeon
