the nerve of a tooth becomes infected or abscessed,
Root Canal Therapy is the only way to save the tooth.
A tooth can become abscessed as a result of deep
decay, a cracked tooth,
or trauma to the tooth.
The only alternative to Root Canal Therapy is an Extraction.
During Root Canal Therapy, the tooth is "numbed" (just like
having a filling). Then the unhealthy
nerve is removed and medication is placed in the tooth to
treat the bacterial abscess (infection). After the infection
is removed and treated, a filling is placed in the roots where
the unhealthy nerve was.
A tooth that has undergone Root Canal Therapy is more brittle
and must be crowned to give the tooth
sufficient strength. The tooth is cared for in the same way
as other natural teeth. Brush and floss daily, and visit your
dentist for regular preventative dental check-ups.
