A root canal is cleaned in a manner that at least partially approximates the actual anatomy of the root canal. An endodontic file instrument is inserted into an exposed root canal, such as an asymmetric root canal, and then rotated and moved in a manner so as to have a plurality of centers of rotation. The file instrument may be moved from side to side and/or in a milling motion and/or using the contours of the root canal as a guide in order to remove substantially all of the pulp material, e.g., from the operative middle portion of the root canal. In this way, less of the surrounding dentin is removed compared to conventional methods. The file instrument may be rotated in a single direction, or it may have a reciprocating motion.
