What is a "root canal"?

A root canal refers to both the inner part of a tooth's root and the dental procedure aimed at treating infected or damaged pulp within that region. The root canal system consists of narrow passages and chambers that house the tooth's pulp, which contains nerves and blood vessels. When the pulp becomes infected or inflamed due to deep decay, trauma, or other factors, a root canal procedure is performed to remove the affected pulp, clean the canal, and seal it with a biocompatible material, allowing for pain relief and the preservation of the natural tooth.
