Endodontic therapy (Root Canal Treatment) is the method by which severely damaged teeth are preserved in the mouth for many years to come. It consists of removing the nerve from the inside of the tooth, disinfecting and sealing its roots. It is performed under local anesthesia and is usually completed in 3 sessions. After the endodontic therapy is completed, it is necessary to restore the tooth with a ceramic crown or inlay to avoid cracks and fractures. This will ensure the tooth longevity.
