Root canal therapy, also known as endodontic therapy, is a dental procedure performed to treat and save a tooth that has become infected or severely decayed. It involves removing the infected or damaged pulp tissue from the inside of the tooth, cleaning and disinfecting the root canals, and sealing them to prevent further infection or reinfection. The term “root canal” refers to the natural space within the tooth that contains the dental pulp, which consists of nerves, blood vessels, and connective tissue.

The need for root canal therapy arises when the dental pulp becomes infected or inflamed due to various reasons, including:

Tooth Decay: Untreated tooth decay can progress and reach the inner layers of the tooth, infecting the dental pulp. Deep cavities that penetrate the pulp chamber often necessitate root canal treatment.

Dental Trauma: A traumatic injury to the tooth, such as a fracture or severe impact, can cause damage to the dental pulp. Root canal therapy may be needed to address the resulting pulp inflammation or infection.

Dental Infections: In some cases, dental infections, such as abscesses, can extend into the pulp of the tooth, leading to pulp inflammation and the need for root canal treatment.

Repeated Dental Procedures: Teeth that have undergone multiple dental procedures, such as fillings or crowns, may eventually require root canal therapy if the dental pulp becomes compromised or infected.

Root canal therapy is often performed over one or more dental visits, depending on the complexity of the case and the tooth’s condition. Properly performed root canal treatment can save an infected tooth from extraction, relieve pain, and restore normal tooth function.

It’s important to note that after root canal therapy, the treated tooth may require ongoing care, such as a dental crown, to protect and strengthen it, as the tooth may become more brittle over time. Regular dental check-ups and good oral hygiene practices are essential to maintain the health of the treated tooth and prevent future dental problems.
