Background: Regular toothbrushing is an important step that removes plaque which is the common risk factor for both periodontitis and dental caries. Commonly prescribed time of brushing by dental professionals is 2 min, despite of which, the average time spent for brushing by the general population is 45 s. Aim: The aim of this study was to determine the relationship between different brushing times from 30 to 180 s, and plaque removal using conventional brushing techniques in the general population. Materials and Methods: Forty participants were included in the study. Study participants brushed for 30, 45, 60, 120, and 180 s randomly. Plaque levels at baseline and after brushing for a specific time period were assessed using the Turesky-modified Quigley–Hein plaque index and a disclosing agent. Results: Plaque removal increased with increased brushing time with maximum removal at 180 s. Conclusions: Dental professionals during health education sessions should highlight the importance of brushing for more than 3 min to achieve maximum plaque removal.
