7. Brushing immediately after consuming acidic foods
“If you’re consuming food and drink that is acidic (such as orange juice), it can contribute to a softening of tooth structure,” says Swan. “If you immediately brush your teeth, the abrasion of the toothbrush on the softened enamel can cause some damage.” To avoid this risk, Swan recommends waiting about 30 minutes before brushing your teeth. This time frame gives the saliva in your mouth a chance to wash away lurking food debris and acids. Can’t wait 30 minutes? Chew sugarless gum. It will stimulate saliva production, and help freshen your breath until you can brush your teeth.
