ROOT
CANALS
Why you need them:
If a tooth's pulp, which contains nerves and blood vessels, becomes
infected or damaged because of decay or injury, root-canal treatment is
often the only way to save your tooth and repair the damage.
Visits:
One
to three, depending on the pulp's condition. If the tooth is abscessed
(the pulp has died and infection has entered the bone), the infection may
have to be drained before the root can be filled.
Durability: The
material used to fill the root canal will probably last a lifetime, but
eventually the filling or crown may need to be replaced.
