ROOT
CANAL THERAPY...................
What
is root canal therapy?
Root
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.
What
causes pulpal nerve damage?
The
most common causes of pulpal nerve damage are:
• 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 and decay
• trauma - a blow to a tooth or the jaw can cause
damage to sensitive nerve tissue within the tooth.
What are the symptoms of pulpal nerve damage?
The following are the most common symptoms of pulpal nerve
damage. However, each individual may experience symptoms
differently. Symptoms may include:
• pain in the tooth when biting down
• tooth pain while chewing
• oversensitivity of the teeth with hot or cold drinks
• facial swelling
The
symptoms of pulpal nerve damage may resemble other oral
health conditions. Consult a dentist, or other oral health
specialist, for diagnosis.
Why
is root canal therapy necessary?
Without
treatment, the infection of the dental pulp will spread
to the bone around the tooth, making it not longer able
to hold the tooth in place.
What
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 drained.
Post-Operative
Care Following a Root Canal
Once
the root canal therapy is completed, there will be changes
to adapt to, including:
• 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
the tooth.
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.
