Why Are Your Teeth Stained?
The most frequent cause of dental stains comes from drinking dark liquids, such as tea, coffee, and red wine. Tobacco products are another culprit. Some teeth are discolored from the time they were formed. Others are darkened due to trauma or a procedure that occurred near the teeth. Certain medications can cause stains. Finally, as teeth age, they tend to lose their white enamel and become yellow.
