In order to treat the compromised tooth, the dentist will drill into its core. The infected nerve is subsequently removed and the canals are shaped using special tools to smooth the walls and ensure no pulp tissue or infection is left. The canals are then filled with a special material that seals off the root canals.
A root canal is part of a naturally occurring space within a tooth that consists of the pulp chamber, the main canal, and more intricate anatomical branches that may connect the root canals to each other or to the surface of the root. The smaller branches are most frequently found near the root end (apex) but may be encountered anywhere along the root length.
Unfortunately, after root canal therapy the tooth often becomes brittle. To protect the tooth from fracture, it is recommended that the tooth be restored and fortified with a crown.
