Root canal therapy is used to repair and save a tooth that is badly decayed or infected. In short, this procedure involves removing the tooth nerve and pulp, followed by cleaning and sealing the inside of the tooth. Without root canal treatment, diseased or decayed teeth would have to be extracted.
What Are Root Canals?
Root canals are tiny passageways that branch off from beneath the top of the tooth, coursing their way vertically downward until they reach the tip of the root. All teeth have between one and four canals.
Many tooth problems involve infections that spread to the pulp, which is the inner chamber of the tooth containing blood vessels, nerves and other tissues. When the infection becomes worse, it can begin affecting the roots. A traumatic injury to a tooth can also compromise the pulp, leading to similar problems.
A diseased inner tooth brings a host of problems. Pain and sensitivity are some of the first indications of a problem, while inside, a spreading infection can cause small pockets of pus to develop, leading to an abscess.
An Amazing Treatment
Root canal therapy is a remarkable treatment with a very high rate of success. It involves removing the diseased tissue, halting the spread of infection, and restoring the healthy portion of the tooth. In fact, root canal therapy is designed to save a problem tooth; before the procedure was developed and gained acceptance, the only alternative for treating a diseased tooth was extraction.
