Ah, the dreaded root canal...
Root canal therapy is considered to be the most feared dental procedure. Does that surprise you?
A survey conducted by the American Association of Endodontists reveals that most people with a fear of the dentist base their fear on someone else's experience, not their own. The inaccurate information about root canal therapy prevents patients from making an informed decision regarding their teeth. There are some patients who go as far as requesting a tooth to be extracted, rather than saved with root canal therapy.
Root canal therapy is usually performed when the tooth cannot be filled or restored any other way because the decay has reached the nerve of the tooth or the tooth has become infected.
The first step in the procedure is to take a digital x-ray to see the shape of the root canals and determine if there are any signs of infection in the surrounding bone. Then Dr. Kinga will use local anesthesia to numb the area near the tooth and access the pulp chamber. The pulp along with bacteria, the decayed nerve tissue and related debris is removed from the tooth. The cleaning-out process is accomplished with the assistance of the rotary endodontic instrument and root canal files.
Once the tooth is thoroughly cleaned, sealer paste and a rubber compound called gutta-percha are placed into the tooth's root canal.
The final step involves further restoration of the tooth. A tooth that needs root canal therapy often has a large filling, extensive decay or other weakness. Therefore a crown, crown-and-post, or other restoration often needs to be placed on the tooth to protect it, prevent it from breaking, and restore it to full function.
