Root Canal Retreatment
In some cases, root canal therapy doesn’t completely heal an infected tooth, and root canal retreatment becomes necessary.
Some of the reasons a root canal fails are your tooth has curved, narrow, or blocked canals. Your tooth may have extra canals that were not found the first time.
Tooth decay or a fracture can expose the roots to bacteria which causes a new infection.
Root canal retreatment removes infection, relieves discomfort, and saves your tooth.
