Each day, approximately 158 million Americans drink tea. What’s that have to do with your teeth? Tea stains your teeth—in fact, because of its higher tannin content, it’s more likely to stain your teeth than coffee. Tannin is a compound that gives tea its dark color.
Of course brushing your teeth daily can help limit surface stains in tooth enamel, and so can rinsing your mouth with water after drinking tea. But research shows that adding a little milk to your tea can help prevent stains in tooth enamel.
The study, published in the November 2014 issue of the International Journal of Dental Hygiene, shows that the casein protein in milk binds the tannins in tea and limits their staining properties. The study showed that the effectiveness of milk on teeth is greater than whitening toothpaste and comparable to some bleaching gels!
Many people like their tea “straight,” without milk or cream. But for those who can tolerate a little milk in their tea, in addition to diligent oral hygiene and regular dental cleanings, it can help keep your teeth white!
