Root canal therapy is necessary when a cavity or crack infiltrates into and infects the tooth’s nerve, causing discomfort and swelling in the area. The procedure removes the decayed tooth material and cleans out the root canal to prevent further damage and save your tooth. It should be noted that some teeth can be so severely decayed that even if they receive root canal therapy they cannot be saved. It is therefore necessary for a tooth’s restorability to be determined prior to initiation of root canal therapy. Additionally, a root canal treated tooth most commonly requires a post & core and crown to be fabricated in order to restore it to function.
If you have been told that a root canal is necessary to save one of your teeth, it is important that you understand why this procedure is necessary and what happens during root canal treatment.
