The timing of when you brush can make a real difference in how well your enamel is protected. Brushing before breakfast allows the fluoride in your toothpaste to form a protective layer before your teeth are exposed to food and drink. Brushing after, particularly after something acidic, risks pushing softened enamel rather than protecting it. If you prefer to brush after eating, waiting 30 minutes first gives your mouth a chance to settle on its own.
