is root canal therapy?
canal therapy is designed to correct
disorders of the dental pulp --
the soft tissue inside the tooth
that contains nerves, blood vessels,
and connective tissue. Teeth with
abscessed, or infected, nerves were
once removed with corrective therapy.
But now, in 95 percent of these
cases of pulpal infection, the natural
tooth can be saved through modern
endodontic procedures. (Also called
pulp specialists, endodontists have
undergone specialized training in
performing root canal therapy.
causes pulpal nerve damage?
most common causes of pulpal nerve
• physical irritation - generally
brought on by aggressive tooth decay
(cavity) reaching down to the nerve
or through deep fillings, which
allows harmful bacteria to reach
the nerve resulting in infection
• trauma - a blow to a tooth
or the jaw can cause damage to sensitive
nerve tissue within the tooth.

does the root canal procedure involve?
Treatment begins with the initial
removal of the tooth crown, or top,
to allow access to the pulpal tissue.
Once the affected pulpal tissue
is exposed, the affected area is
removed. The area surrounding and
containing the pulpal tissue is
carefully cleaned, enlarged, and
shaped to provide a clean, bondable
surface for filling with a permanent
filler to prohibit any further infection
and discomfort. After filling, a
crown is fabricated to complete
the rescue and restoration of the
natural tooth. The procedure is
generally spread over several visits
to assure the infected pulp and
associated bacteria have been adequately
Care Following a Root Canal
Once the root canal therapy is completed,
there will be changes to adapt to,
• brittleness - a pulp-less
tooth is more brittle than a non-treated
tooth and great care should be used
to avoid fracture and chipping
• discoloration - a non-vital
tooth may become discolored over
time, which can be treated with
bleaching. In most cases, the discoloration
poses no threat to the health of
In addition, soft tissue inflammation
may be a source of irritation in
the weeks following surgery. Consult
your dentist, or other oral health
specialist, for a treatment approach
to help control any post-operative
swelling and discomfort.
