An untreated cavity or traumatic injury can leave the internal structure of your tooth vulnerable to infection. Sometimes, bacteria can spread to the pulp (soft inner-tissues of the tooth), causing a lot of pain and discomfort. When infection spreads this deep, it can lead to tooth loss if it’s not addressed quickly.
This is where root canal therapy comes in. Endodontic (root canal) therapy aims to get rid of the infection and protect the tooth from further infection, hopefully saving you from the hassle of an extraction. A tooth that has had root canal therapy will need a crown to protect the tooth since it is no longer vital. The great thing is that root canal therapy can now be done in one visit and thanks to modern techniques this is no longer a service to fear.
