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

Dentist billboards are lies. Teeth are not naturally white, they’re *ivory*. That’s slightly yellow-ish.
