Root Canal

Root Canal Dentistry at Kaiyen

Root canals are necessary when the pulp layer of a tooth becomes infected. Infection can lead to the loss of a tooth so it is necessary to remove the infection with root canal therapy.

What Is Root Canal Treatment?

To understand what a Root Canal treatment entails, it helps to know something about the anatomy of the tooth. Inside the tooth, under the white enamel, is a hard layer called the dentin and the soft tissue is known as the pulp. The pulp contains blood vessels, nerves, and connective tissue, which forms the surrounding hard tissues of the tooth during development.

The pulp extends from the crown of the tooth to the tip of the roots, where it connects to the tissues surrounding the root. The pulp is important during a tooth’s growth and development. Once a tooth is fully mature, it can survive without the pulp, because the tooth continues to be nourished by the tissues surrounding it.

The procedure is generally comfortable and saves the natural tooth, prevents the spread of infection, and returns the smile to complete health.

The Procedure

Before the procedure begins, the area is completely numbed using a local anesthetic. Once the area is numbed, a rubber dam is placed around the infected tooth to protect the mouth and to prevent anything from falling into the back of the throat.

In order to access the infected tooth pulp, an opening is made through the top of the tooth to get down into the pulp chamber. A tiny instrument, called a dental file, is then carefully used to clean out the infected tissue and to shape the root canals to receive a filling. X-rays may be done to ensure that all of the infected pulp is removed before the filling is placed.

After the infected pulp is removed, the restoration is placed. In most case a crown is placed to protect and strengthen the tooth. However, if the tooth is severely broken down, it may be necessary to start by building up the tooth with a post and core.
