Teeth
are held in the jaw by their roots.
Inside the roots there are nerves
and blood supply. When the tooth is
healthy; the nerves are healthy the
nerves are alive. Decay or trauma
however may cause them to die. Left
untreated, an abscess may form at
the tip of the root. The root canal
is the space within the root of the
tooth which contains blood vessels
and nerves. These tissues travel from
the apex of the tooth (tip of the
root) to an enlarged cavity within
its body (pulp chamber). This tissue
is known as the pulp; it supplies
nourishment and sensation to the tooth.
It’s interesting to note that
the only “type” of sensation
the pulp can perceive is pain. Hot,
cold or any stimulation – is
perceived as pain. Root canal treatment
refers to dental treatment involving
the nerve space or root canal of the
tooth. The procedure involves removing
the infected nerve, cleaning out the
damaged pulp and filling the canal.
It effectively saves the tooth and
alleviates the associated pain. The
purpose of root canal therapy is not
only the elimination of pain and swelling,
it also aims at getting rid of bacteria
causing the infection from recurring.
It accomplishes this by cleaning the
necrotic pulp from the canal and sealing
the root against bacteria. One of
the most common reasons for root canal
treatment is an infected or abscessed
tooth, which may result from a deep
cavity, or a fracture. Occasionally,
trauma, such as a sudden blow to the
mouth, can result in damage to the
pulp of a tooth. |
