A method of removing tooth structure includes applying an abrading implement to a first tooth by applying a first hand piece to the abrading implement with a shank that affixes the abrading implement. The abrading implement is moved against a tooth under conditions to remove tooth material from the tooth while erratic behavior is modified by use of a second hand piece that is configured to be held by a second hand. The second hand piece interfaces with the shank proximal to the location where the abrading implement is affixed.
