Root canal therapy

When does a tooth require root canal therapy?

The tooth comprises of enamel, dentin and pulp. The blood vessels and nerves of the tooth are located in the pulp cavity. If the pulp tissue becomes inflamed, damaged or necrotic for one reason or another, the tooth needs root canal therapy. Often a deep cavity that extends into the pulp underlies an inflammation of the pulp. In addition to dental decay, the pulp may also be damaged as a result of a trauma or excessive biting pressure. If the tooth does not receive root canal therapy, the inflammation can spread to the root tip and jaw bone.

What does root canal therapy mean?

In root canal therapy, the pulp is opened and the inflamed or damaged tissue is carefully removed. After opening, medications are often placed in the canal. The medication is left to act until the next visit. The pulp canal(s) are thereafter filled with root filling materials. Finally, the tooth is filled. A root canal treated tooth functions normally in the same way as an original tooth. Root canal therapy may, however, make the tooth more fragile or discolored. With the several phases involved, root canal therapy often requires a few visits.
