Root canal treatment, also known as root canal therapy or endodontic therapy is a type of dental treatment in which the infected pulp of a tooth is eliminated, and the tooth's hollow roots are re-filled.
The tooth's root is usually made up of nerve tissue, blood vessels, and connective tissue. It's very susceptible to infection if a cavity is large enough to reach it. If a large cavity forms, root canal treatment may be the only way to save the tooth from extraction.
Why should the pulp be removed? When the tooth's pulp is damaged or infected due to tooth decay, chips or cracks in the tooth or trauma, bacteria begin to multiply very fast in the pulp chamber. This can lead to an abscess in the tooth itself – a pocket full of pus that usually appears at the end of the root. Dental pulp infections can also lead to more problems, including:
● Bone loss at the root of the tooth
● Swelling around the tooth, neck, face and even head
● Pus drainage into the gums or cheek
A root canal treatment procedure can help patients avoid these problems altogether, and in most cases, the tooth can be saved and further restored using other techniques (such as a crown or bridge). The tooth itself will maintain its full functionality after root canal treatment.
Root canal treatment or root canal therapy is recommended for patients with a damaged or infected tooth pulp. Using this type of endodontic therapy is better than simply extracting the tooth since the patient's natural teeth can be used as a foundation for other types of dental restoration (a dental crown or a bridge).
