The color in these foods and beverages comes from chromogens, intensely
pigmented molecules with an unfortunate penchant for latching on to dental
enamel. But the presence of chromogens isn’t the only thing that determines the
staining potential of foods and beverages.
Acidity is another factor. Acidic foods and beverages -- including some that
are not brightly colored -- promote staining by eroding the dental enamel,
temporarily softening teeth and making it easier for chromogens to latch on.
And finally, a family of food compounds known as tannins promotes staining by
further boosting chromogens’ ability to attach to enamel.
