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.
Consuming coffee, tea and soda in large quantities can cause your teeth to yellow or cause unsightly brown stains to occur between teeth as well as on the surface. Cutting down on the amount of caffeine you consume can help prevent further staining and damage to your teeth.
