If your tooth's
nerve chamber becomes infected by decay, or
damaged by trauma, root canal treatment
is often the only way to save your tooth.
Inside the hard
outer shell of each tooth is a specialized
area called the pulp or nerve chamber. The
pulp chamber contains a system of blood
vessels, lymph vessels and nerves, the pulp,
which enter from the bone through the root
canals. This system provides nourishment for
the cells within the tooth.
Deep tooth
decay or other injury can cause damage to or
infection of the tooth pulp. In a root canal
or endodontic treatment, the dentist removes
the damaged or infected pulp and replaces it
with a special filler which helps maintain the
remaining tooth structure.
Some
indications of the need for root canal
treatment may be:
- Spontaneous
pain or throbbing while biting.
- Sensitivity
to hot and cold foods.
- Severe decay
or an injury that creates an abscess
(infection) in the bone.

PROCEDURE
Step 1
After the
tooth is anesthetized, an opening is made
through the crown into the pulp chamber. |
Step 2
The length
of the root canals is determined. |
|
|
|
Step 3
Unhealthy pulp
is removed. Canals are cleaned, enlarged
and shaped.
|
Step 4
Canals are
filled and sealed. A metal post may be
added for structural support or to
retain restorative materials. |
|
|
|
Step 5
The tooth is
sealed with a temporary filling. Usually a
gold or porcelain crown adds further
protection.
|
The material
used to fill your root canal will probably
last you a lifetime, but eventually the
filling or crown may need to be replaced.
Be sure to
follow the special home care instructions
provided by your dental professional.
