Peroxide toothpaste is an over-the-counter paste that uses hydrogen peroxide to break surface pigments while you brush. Shoppers reach for it after coffee, tea, or red wine, and for a cleaner gum line than mint paste alone. Treat it as toothpaste, not bottled 3% rinse: the paste is buffered so enamel sees a short, controlled dose twice a day.
Match the labeled peroxide strength to how often you brush, then read RDA and sensitivity notes before swapping your regular tube.
