A
root canal on
a tooth is necessary if there is damage to the nerves inside the
roots due to trauma, deep cavities, irritation by large fillings
or gum disease. |
| |
| Root
canal treatment may be necessary regardless of whether there is
pain on
a tooth. |
|
| |
Root
canal treatment is generally completed in one or two appointments.
During the treatment the tooth is opened to expose the
nerves, the
nerve is then removed and the space it occupied is cleaned and disinfected.
A special filling is then used to replace the missing nerves in
order to seal and prevent future infection of the roots.
|
| Since
a great deal of tooth needs to be removed in order to gain access
to the nerves, a
post and buildup is
used to replace the missing structure after the root canal is
finished. The tooth is then covered with a crown in order to prevent
fracture. |
