Root Canal Therapy
Endodontics is the term use to describe the treatment of the
internal portion of an abscessed tooth, dead tooth or a tooth
damaged and exposing the nerves. The most common term for this
procedure is a root canal treatment. A tooth is like a hollow tube
open at the tip of the root and closed at the other end, the crown
(the part that we see in the mouth). If the nerves and the blood
vessels in this hollow tube get damaged, the treatment required is
a root canal. The process is the cleaning of the internal hollow of
the tooth and then the placement of special root canal filling,
thus retaining the tooth in the mouth. If a damaged tooth requiring
a root canal treatment is left untreated, the eventual treatment
will be the extraction (removal) of the tooth.
A tooth becomes abscessed due to a bacteria invasion of
the internal part of the tooth (the pulp). The rapid growth of
bacteria produces pressure and hence extreme pain.
Quite often a tooth may be dead. The content of the pulp
chamber dries up leaving a void in the hollow of the tooth. Often,
heat can cause pain in such a dead tooth. Most often a dead tooth
is detected on an X-ray of the root of the tooth. Most dead teeth
are a result of trauma (blow to the tooth).
Tooth with Exposed
Often an accident may cause the fracture of the top of
the tooth. If such a fracture exposes the nerves of the tooth, the
only option is usually a root canal treatment. A minor nerve
exposure may be treated with special medication and a filling.
