Endodontic Therapy (Root Canal)

If you are in need of root canal therapy, the following information will help you to understand the procedure.

Inside of all normal teeth is a space containing nerves, blood vessels and live soft tissue called the dental pulp. Occasionally, the pulp tissue is abused by trauma, deep decay, large fillings, crowns or other factors, and the pulp tissue becomes necrotic (dead). Usually, pulp death results in pain or bone destruction visible on dental radiographs (x-rays).

Treating a necrotic (dead) pulp is a delicate procedure requiring the following steps.

1. A small hole is made in the tooth to allow access to the dead pulp tissue.
2. Using a series of small files/instruments, the dead pulp tissue is removed from the internal space of the tooth.
3. When the internal space of the tooth is hollow and cleared, this space is filled with a rubber-like material called gutta percha.
4. If the tooth has been severely weakened, it may need a supportive post placed internally, and a subsequent crown (cap) for strength.

Root canal therapy is approximately 95% effective in restoring the tooth back to normal function. However, occasionally mild discomfort lingers for a period of a few weeks to a few months before the tooth feels normal again.
