A root canal is a common dental procedure performed to save a severely infected or damaged tooth. Inside each tooth, there is a soft tissue called the dental pulp, which contains nerves, blood vessels, and connective tissues. When the dental pulp becomes infected or inflamed due to deep decay, cracks, trauma, or repeated dental procedures, a root canal treatment is necessary to remove the infected pulp and save the tooth from extraction.
Severe Toothache: A severe and persistent toothache is often an indication of an infected dental pulp. Root canal treatment can alleviate the pain by removing the infected tissue and relieving pressure inside the tooth.

Dental Abscess: An abscess is a pus-filled pocket that forms at the root of the tooth due to a bacterial infection. Root canal treatment is essential to prevent the spread of infection and save the tooth from extraction.
