Root canal treatment is a treatment sequence for the infected pulp of a tooth during which the infected pulp is removed, and the inside of the tooth is cleaned and sealed, which results in the elimination of infection and the protection of the decontaminated tooth from future microbial invasion.
When the pulp becomes infected or inflamed, root canal therapy is necessary. The inflammation or infection may be a result of:
Deep decay
A crack or chip in the tooth
Repeated dental procedures
Injury
When an inflamed or infected pulp is left untreated, it can cause pain and may develop into an abscess.
You may require root canal therapy if you experience any of the following symptoms:
Severe pain when chewing or biting
A chip or crack in the tooth
Long-lasting sensitivity to hot or cold temperatures
Swollen or tender gums
Deep decay
