What is Root Canal Therapy?

Root canals are the thin passages that run from the soft inner tissue of your tooth (pulp) to the tip of the root of your tooth.  These canals may become infected in a variety of ways, most commonly as a result of untreated cavities.  Because the canals contain nerve fibers, infections of this sort are often accompanied by varying amounts of pain. 

Root Canal Procedure Root canal procedures not only preserve your dental and oral health, but also improve the appearance of teeth darkened by infection.  They are likewise a preventative measure to help you to avoid costly restorations to replace a tooth lost to decay and infection. 

Many people are concerned by the potential pain of a root canal procedure.  You may be surprised to learn that modern day root canal therapy is usually painless as a result of new and more effective pain medications and techniques. 

Procedure

After sufficiently numbing the area, your dentist creates an opening on the surface of the tooth.  He then gently removes any decayed tissue or bacteria from the canal.  The inside of the tooth is then thoroughly cleaned and supplied with initial filling material, accompanied by medications to soothe the area.  

A final filling, such as those used to fix cavities, is applied to the surface of the tooth.  In many cases, a crown is placed instead of a filling to provide more structural support for the tooth. 

Most often, both the diagnostic exam and the root canal procedure can be completed in one office visit.
