Coffee and Tea Effects on Teeth. Coffee and tea are especially tough on teeth, because tannic acid scrapes into the pits and grooves of tooth enamel and can stain teeth. The amount of coffee a person consumes daily does affect the color of their teeth.
In order to effectively manage tooth discoloration, it is important to recognize the causes. These include: 1  Foods/Drinks: Coffee, tea, colas, wines and certain foods (e.g., potatoes, cherries, blueberries) can cause extrinsic tooth stains.  Tobacco Use: Smoking or chewing tobacco can result in discolored teeth.
