Having root canal treatment on a tooth does not mean that the tooth will need to be pulled out in a few years. Once a tooth is treated, and restored with an appropriate restoration, it has a longevity of 15-20 years on average.
Endodontics is the branch of dentistry that deals with diseases of the tooth’s pulp. The pulp is found in the center of the tooth and in canals (called root canals) inside the root of each tooth. Pulp includes connective tissue, nerves and blood vessels. Pulp nourishes the tooth when it first emerges through the gum. Once the tooth matures, the pulp can be removed without destroying the tooth.
Removing the pulp is called endodontic treatment, but it is often referred to as root canal treatment or root canal therapy. Many people refer to pulp removal as “having a root canal.” Root canal treatments are quite common. In the United States, they save about 24 million teeth each year.
