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)

Answer 1

Dentin is a material located under the slightly translucent enamel coating on the outside of your teeth is typically yellow. The amount of yellow that comes through is influenced by many factors; enamel wear, age, genetics, etc.

Basically, having yellow teeth (not otherwise caused by staining) is normal.
