Root canal

Definition

A root canal is a dental procedure used to treat infection at the center of a tooth (the pulp) and involves removing the infected tissue to prevent further damage. It is crucial for saving a tooth that would otherwise need to be extracted.

5 Must Know Facts For Your Next Test

1. Root canals are often necessitated by bacteria entering the pulp through cavities or cracks in the tooth.
2. The procedure aims to remove all bacteria from the root canal system, which is then cleaned, filled, and sealed.
3. If left untreated, infections in the pulp can spread to surrounding tissues, leading to more severe conditions such as abscesses.
4. Common symptoms indicating the need for a root canal include severe toothache, prolonged sensitivity, and swelling around the affected tooth.
5. Microbial factors such as Streptococcus mutans and Lactobacillus are commonly implicated in causing infections that lead to root canals.
