You may have heard that drinking soda can stain your teeth. This is primarily due to the sugar and acidity in the drink. Dark-colored sodas may stain your teeth a bit more than clear sodas, but both can wear away tooth enamel and cause decay. The best way to combat this problem is to rinse your mouth with water after drinking soda. This will wash away the sugary residue that can linger on your teeth. Don't brush your teeth right after drinking soda, as this can wear away enamel that's been softened by the soda's acidity. Rather, brush your teeth later in the day using a fluoride-rich toothpaste to help protect your enamel. You can pick up toothpaste alongside your soda through Instacart and get everything you need in one delivery.
