Your dentist will perform a root canal treatment in order to restore an infected tooth. The process involves removing the caries, remainder of the tooth including the root canals are cleaned, disinfected and then sealed. Due to the amount of tooth structure destroyed, a crown is routinely recommended to protect the teeth post root canal treatment.
Tooth decay is the primary reason many patients may require root canal therapy. While the decay advances deeper into the tooth, it ultimately extends to the pulp. At this point, the best method to clear the infection and restore the tooth, will be by undergoing root canal (or endodontic) treatment.
