Why can’t we just spend however long it takes to brush our teeth over and over again until they’re as clean and white as they were when we first got them? (Like dentist office billboard advertisement levels of white teeth)

Question

Or is restoring a former brilliance of your teeth impossible through normal dental hygiene practices without cosmetic dentistry?

Answer 1

Because teeth aren’t perfectly white! Enamel is naturally slightly yellow. Making teeth whiter is very easy to photoshop in ads, but in real life the only way to get perfect white teeth is with bleaching. Sure, some of the color in your teeth comes from staining – but not all of it.
