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.
Practicing good oral hygiene is perhaps the best way to prevent coffee stains on your teeth. You should be brushing and flossing regularly, and using a mouthwash can also help. These are the best ways to fight plaque and remove tannins that remain after having a cup of coffee.
