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?

In: Biology

Answer 1

Because advertisements are lies. Natural teeth are NEVER the colour of bleached paper, and they were never that colour, not even when you got them.

In tooth anatomy in dental school the tooth is described as having an yellow-white colour gradient from yellow-ish white at the base to ivory to translucent-white at the top, at least for the frontal teeth. They are not a single colour, and most certainly that colour is not pearly white.

The other answers here are also correct.

Don’t believe ads. They are not your friend.
