Endodontics, more commonly known as root canal therapy, is a procedure where the nerves of the tooth are removed; leaving the tooth intact. An infected (or abscessed) nerve is the most common cause of a toothache and, until root canal therapy, required extracting the tooth. Rotary Endodontics is a way of performing the root canal utilizing a specific electrical handpiece. This tool often makes the process faster and allows the dentist to perform the process with greater ease.
