Root Canal >
What could cause the pulp tissue to become diseased and lead to root canal problems? One potential source of infection is untreated tooth decay, which can allow bacteria from the tooth's surface to work its way deep inside. A crack or fracture in a tooth could offer another pathway for microorganisms to infect the pulp.
It's important to remember that root canal treatment doesn't cause pain; it relieves pain. A typical root canal procedure is performed with local anesthetics and doesn't cause any more discomfort than having a filling. Here's what to expect:
First, you will receive anesthesia (usually a numbing shot) — and for many patients, the worst is now over. Next, a small opening is made in the tooth surface to give access to the pulp chamber and root canals. Then, tiny instruments are used — often with the aid of a microscope — to remove dead and dying tissue from inside the narrow passages. These passages are then cleaned, disinfected, and filled with a safe, inert material. Finally, the opening in the tooth is sealed to prevent contamination.
Other endodontic treatments may be recommended for removing sources of infection and preventing future problems. Following an endodontic procedure, it may be necessary to have a restoration (such as a crown) placed on the tooth to restore it to full function and aesthetic appearance. After that, with proper care of the restored tooth should last for many years.
