Root Canal Treatment is used to treat a tooth that has a diseased nerve most often caused by a crack in the tooth or a deep cavity. Once thought of as a long and sometimes painful procedure can now be accomplished fairly quickly (usually in one visit) and painlessly. The utilization of digital radiographs, contemporary instruments and filling materials, makes preserving a tooth with a diseased nerve a viable treatment option. Following root canal therapy a tooth will need a crown to strengthen the remaining tooth and provide for a long lasting treatment. Alternatives to root canal treatment would be extraction and replacement of the missing tooth with a fixed bridge or an implant supported crown.
