At Northridge Dental Group, we do all we can to save your natural teeth. One treatment in particular can help us achieve this goal — root canal therapy. Many patients have heard of a root canal and have a bad impression without ever having received treatment. If you are unfamiliar, a root canal is the process of removing infected nerve tissue from the inside of the tooth. The root is then cleaned, disinfected, filled, and sealed. If a root canal is not performed when needed, the last resort is to extract the tooth to remove the infection.
