Endodontic therapy is the proper name for what is commonly referred to as a root canal. The root canal is actually the naturally occurring canal that runs through the roots of each tooth, leading to a pulp chamber. These canals can become infected by microbes that eat away at your teeth. When this happens, endodontic therapy is used to clear out the infection with tiny files that scrape the infected tissue away.
Rotary endodontics is a new method of endodontic therapy that utilizes an electric hand-piece instead of manual files. Because rotary endodontics uses an electric instrument, there is no associated drilling noise and the procedure can be finished much more quickly.
