An objective methodology was employed in the present in vitro study to assess bristle pressure required for plaque removal from the enamel surface of freshly extracted teeth. This bristle pressure has indirectly reflected the plaque tenacity or total attachment force of the plaque on the tooth surface. Equipment used to measure bristle pressure was especially fabricated for this purpose and described in detail with illustrations. The mean bristle pressure required for the removal of 1‐day, 2‐day, and 3‐day old plaque was 5.509 gms/cm 2 , 7.757 gms/cm 2 and 14.28 gm/ cm 2 which shows a ratio of 5:7:13 respectively, indicating an increase in plaque tenacity as it advances in age Further, the increase in tenacity of plaque from 2‐day to 3‐day was more as compared to the increase in tenacity from 1‐day to 2‐day plaque
