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

Teeth are not naturally pure white; they have to be bleached to be that way.

And even then, brushing too much will damage your gurms, basically scrubbing them raw where they meet the tooth.
