The short science of whitening
Teeth whiten through two fundamentally different mechanisms: surface stain removal (abrasion or mild chemical lift) and intrinsic bleaching (hydrogen peroxide or carbamide peroxide oxidizing deep pigment molecules inside the enamel). Only the second mechanism produces dramatic whitening. The first produces only superficial, temporary brightness.
Surface methods include baking soda, charcoal, and most "whitening toothpastes." They work on coffee and tea stains but not on intrinsic yellowing. Bleaching methods include hydrogen peroxide, whitening strips (typically 6-14% peroxide), LED kit gels, and professional in-office treatments (up to 40% concentration). These penetrate enamel and lighten the dentin beneath, producing the 2-8 shade improvements most people actually want.
The trade-off: higher peroxide = faster results but more sensitivity risk. Our guides help you pick the right concentration and protocol for your starting point — with specific recommendations for sensitive teeth and users who prioritize natural approaches.
