Teeth whitening works primarily through bleaching agents like hydrogen peroxide and carbamide peroxide, which break down stain molecules (chromogens) in the enamel and dentin to lighten the tooth's color, while mild abrasives in toothpaste (like baking soda) remove surface stains for a cleaner look. More powerful results come from professional treatments with higher concentrations, but at-home options like strips and custom trays also use these peroxides effectively over time.
