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.
Caffeinated drinks, herbal tea, soda drinks, wines and also some vegetables and fruits such as, apples and potatoes can discolor the teeth. Insufficient brushing and flossing in order to get rid of tooth plaque and stains from coffee and tobacco could cause yellow tooth.
