Deep tooth decay or other injury can cause
damage to or infection of the tooth pulp.
In a root canal or endodontic treatment,

which helps maintain the remaining tooth

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.
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
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.
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.
