There are several factors as to why coffee stains teeth. First of all, the dark brown color of coffee does cause teeth to stain. It is the other factors that determine how much it stains. Those factors are, how much coffee a person drinks, the roughness of the person's enamel of their teeth, the organic salts in the saliva, the amount of saliva an individual has, and how the person's oral hygiene is.
