Long Description
A canal in dentistry refers to the internal passage within a tooth that contains nerves, blood vessels, and connective tissue. The most well-known example is the root canal, which extends from the pulp chamber inside the tooth down to the tip of the root. This structure plays a crucial role in nourishing the tooth and maintaining its vitality.
When the pulp inside the canal becomes infected due to deep decay, cracks, or trauma, root canal therapy is required to remove the diseased tissue and prevent further damage. During this procedure, the infected pulp is removed, the canal is cleaned and disinfected, and the space is sealed with a biocompatible material to prevent reinfection.
Proper oral hygiene and regular dental visits help prevent canal infections. If left untreated, an infected canal can lead to severe pain, abscess formation, and even tooth loss. Root canal treatments, when performed promptly, can save a tooth and restore its function for many years.
