What affects does coffee could bring to teeth? why will teeth turn yellow if you drink too much coffee?

Dark pigments in foods, beverages, and cigarette smoke can bind to your enamel, staining the surface of your teeth. If you're concerned, you might try using a straw when you drink dark-colored juice or cola to minimize its contact with your teeth. Tannic acid, the bitter compound in coffee, tea, and wine, can also cause yellow or brown stains when it combines with other particles on your teeth. Dairy products and saliva help neutralize this acid, so add a splash of milk to your coffee and stimulate saliva production by chewing sugarless gum. No matter what you do, though, your teeth will yellow as you age. Deep grayish blue discoloration in the dentin (the material beneath the enamel) is usually hereditary, but teeth may also turn gray if they break or are knocked so hard that the roots die or if they were exposed frequently to the antibiotic tetracycline while they were still developing.

you answered your own question they discolor because coffee stains

The strong color...just like red wine, stains teeth. Our enamel isnt that strong after all.

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. I hope this helps! If you need a reference it is: Dental Hygiene Concepts, Cases and Competencies by Daniels and Harfst. Mosby, Inc. 2002.
