A Reddit user in the LifeProTips thread suggests people are using excessive amounts of toothpaste due to marketing tactics. The user wrote “The big toothpaste industry wants you to use a giant amount each time, but just use a portion the size of a pea and you’ll be fine, trust me.” They claimed advertisers show models using large amounts to increase product consumption rates. One commenter said “I started doing this and my toothpaste lasts me 6 months and I use it twice a day.” According to Arm and Hammer, adults need “at least” a pea-sized portion, while children under three need rice grain-sized amounts. However, some disagreed, with Danish users recommending pinky nail-sized amounts and Swedish users suggesting two centimeters. A National Library of Medicine study found one gram of toothpaste provided highest cleaning efficiency regardless of brushing time. (Story URL)
