Coffee lovers: here’s how to prevent dental stains
Coffee contains chromogens and tannins—pigmented compounds that cling to enamel and gradually darken the teeth. To reduce their effect, rinse with water after drinking to dilute pigments, and wait 20–30 minutes before brushing to avoid scrubbing softened enamel. Using a straw for iced coffee limits contact with front teeth. Regular professional cleanings remove deeper discoloration, and whitening treatments can address long-standing stains.
