Your smile is often the first impression people receive about you. Many factors affect the whiteness of your teeth. Deeply pigmented beverages like red wine and black coffee may stain the enamel on your teeth.
In contrast, highly acidic beverages can strip away your enamel, making it more vulnerable to staining as well. Soda is a prime example of an acidic drink that can erode your tooth enamel and lead to stains.
