You might not be replacing your toothbrush often enough (we know, it’s hard to find the color you like). The American Dental Association recommends you trade in your toothbrush every three to four months, or earlier if it’s frayed or loses shape. Recent studies from You might not be replacing your toothbrush often enough (we know, it’s hard to find the color you like). The American Dental AssociationOral-B Laboratories found that after just one use, a new brush removed 13 percent more plaque than a brush worn down to simulate three months of use. Compared to the old brushes, not only did the new ones remove 24% more plaque between the teeth, but they also reduced gingivitis (inflammation of the gums) by almost half.
