If you just eaten some grapefruit wedges or sipped a glass of orange juice, stay away from your toothbrush. Citrusy foods and beverages leave acid on your teeth. Brushing immediately after eating or drinking rubs the acid further in an can erode enamel. When enamel on your teeth wears away, the softer dentin layer underneath is exposed, leaving you vulnerable to tooth sensitivity and cavities. Once enamel is gone, its gone. Delay brushing a full 60 minutes after a citrusy meal or snack.
