ROOT
CANAL THERAPY
Root canal therapy is
needed when the nerve of a tooth is affected by decay or infection.
In order to save the tooth, the pulp (the living tissue inside the
tooth), nerves, bacteria, and any decay are removed and the resulting
space is filled with special, medicated, dental materials, which
restore the tooth to its full function.
Having a root canal done
on a tooth is the treatment of choice to save a tooth that otherwise
would die and have to be removed. Many patients believe that removing
a tooth that has problems is the solution, but what is not realized
is that extracting (pulling) a tooth will ultimately be more costly
and cause significant problems for adjacent teeth.
Root canal treatment
is highly successful and usually lasts a lifetime, although on occasion,
a tooth will have to be retreated due to new infections.

and symptoms for possible root canal therapy:
What
does root canal therapy involve?
A root canal procedure
requires one or more appointments and can be performed by a dentist
or endodontist (a root canal specialist).
While the tooth is numb,
a rubber dam (a sheet of rubber) will be placed around the tooth
to keep it dry and free of saliva. An access opening is made on
top of the tooth and a series of root canal files are placed into
the opening, one at a time, removing the pulp, nerve tissue, and
bacteria. If tooth decay is present, it will also be removed with
special dental instruments.
Once the tooth is thoroughly
cleaned, it will be sealed with either a permanent filling or, if
additional appointments are needed, a temporary filling will be
placed.
At the next appointment,
usually a week later, the roots and the inside cavity of the tooth
will be filled and sealed with special dental materials. A filling
will be placed to cover the opening on top of the tooth. In addition,
all teeth that have root canal treatment should have a crown (cap)
placed. This will protect the tooth and prevent it from breaking,
and restore it to its full function.
After treatment, your
tooth may still be sensitive, but this will subside as the inflammation
diminishes and the tooth has healed.
You will be given care
instructions after each appointment. Good oral hygiene practices
and regular dental visits will aid in the life of your root canal
treatment.
