If your tooth's nerve chamber becomes infected by decay, root canal treatment is often the only way
to save your tooth. Inside your tooth's hard outer shell is a nourshinging pulp of blood vessels, lymph vessels and nerves.
The root canals, which contain the pulp, extend to the bone. Deep tooth decay, or an injury, can cause serious damage and
infection to the pulp's nerves and vessels. Root canal, or endodontic treatment, cleans out the infected pulp chamber and
repairs the damage.
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 and abcess (infection) in the bone.
After the tooth
is anesthetized, an opening is made through the crown into the pulp chamber. The length of the root canals is determined.
Unhealthy pulp is removed. Canals are cleaned, enlarged and shaped. Canals are filled and sealed. A metal post may be added
for structural support or to retain restorative materials. The tooth is sealed with a temporary filling. Usually a gold or
porcelain crown adds further protection. |
