Root canal therapy is a type of procedure that can save a tooth from extraction through the cleaning of the entire tooth system. Teeth can become injured for a variety of reasons. This can be anything from accidents to poor dental hygiene. Once the tooth is injured, cracks and breaks can ensue which leave the tooth susceptible to the naturally occurring bacteria in the mouth. This bacterium invades the tooth through the broken enamel and then continues to work on into the dentin, pulp, and finally the base of the tooth.
Root canal therapy is done by removing the diseased tissue inside the tooth. This is done so that the healthy tissue can continue to thrive without further threat of disease. Then the passageway that leads from the pulp to the base must be cleaned much in the same way to rid it of any decay, disease, bacterium, or other pollutants. Once the area has been restored to a healthy state, it will be sealed. In some cases, it may be necessary to wait a day or two to seal it to allow for the infection to drain.
Root canal therapy can result in having a crown placed on the affected tooth or teeth once this procedure is complete. This is a multiple visit type of procedure because first the tooth must be shaped, the mold taken, and the then crown will be ordered. In the meantime, a temporary crown will be placed to seal the tooth.
Root canal therapy has a very high success rate when combined with proper oral hygiene such as brushing, flossing, and continuing to attend regularly scheduled checkups with the dentist.
