Abstract
An interproximal dental strip with a serrated zone flanked by abrasive zones in repeated longitudinal succession along a side face of the strip. The abrasive zones have a plurality of abrasive sections with non-abrasive sections between. The abrasive sections are inclined with respect to the side edges of the strip such that only a portion of each abrasive section makes grinding contact with a tooth at any given time for more controlled and effective working of the strip.
